I learned about grinding off mill scale from this channel, and when I started paying attention I noticed I was the only one in my shop who did that, and everyone else in the shop told me I was wasting time by doing so. I just let my welds speak for themselves, and watch other guys' welds fail because they didn't do the prep work.
I work in a ship yard building a Royal Navy vessel in Canada. I do this process every day for the ships outter seams. Full pen welds and then UT scans for quality assurance. Overhead, vertical and flat gouging with 3/8 gouging rods. The mouse holes are the trickest always be sure to stagger your tie ins and clean your welds from defects and youll pass everytime!
I just switched from mig to flux core today in my classes, I was suprised how smooth the beads came out, I did a T joint at 320 speed at 24. Im so glad I got into this trade it is so much fun and you meet some awesome guys, its an enviroment where all you want to do is learn more about it.
I’m starting 4G mig on Monday. I feel the same about working in welding. Seems like there are many different opportunities that are cool kinds of work. Like underwater welding or automotive if you like cars, pipeline, structural...just so many different routes a welder can take. Edit: I meant Tuesday not Monday. Monday is Columbus Day
Starting t joints. 20 300. Coming out to be a beautiful weld. Got the gauge out and the teacher looked at it and it was a near perfect weld (my end was short)
Excellent vid! The last time I did that type of weld was during my first year, Mechanical Engineering back in 1987 Only difference is, back then we had to do it manually, even the back gouging ( we used a special type of hollow carbon rods), and we had to first fill the bevel with a stick weld, by hand.( lol I think we used 7018 rods)..Watching this vid brought back lots of memories. Back then I really enjoyed welding practical although my course focused more on Welding & MaterialsTechnology. Thanks for posting and explaining the method used, step by step!
I'm Soo thankful for these videos. I've been down off work for 16yrs now, due to an accident pulling into my job. Neck reconstruction. Anyhow this keeps my spirit up, and I enjoy this. Keep em coming fellas!
Gus M ummm ya ive been a certified welder longer then these new guys on this channel. Bob was weld.com. Now all we get are videos of flat position structural and grinding. Lmao. Has there been a GTAW pipe video since Bob quit? Lets watch a guy make a downhand weld look like Ray Charles and Stevie Wonder did it. Lmfao. Unfollowing this channel because weld.com just isnt good anymore.
The boiler shop, I worked in; (when I was 16), had an automated welder that welded donuts together to make 36" bends for coal shutes. My job was going up inside them and air-motor grinding the root smooth. ( I almost lost my hearing from that job.) It was awesome to watch those two half donuts, lifted in place and watched an inside tho hole, torch and an outside the circumference torch. They were running two speeds at the same time...not as far to weld in the center, but about 10 feet outboard side. Both were vertical and the flux depositors would make a hill of flux and the solid wire would weld thru it. The heads were stationary and the donuts rotated on Hugh "V" Rollers. That was over 50 years ago! Boy hidy, automation sure has gotten better in that length of time! Bill from Tn. 🇺🇸
I don’t like it he didn’t wire wheel it after his fill pass and welded right over the top of slag and then you said it would pass it would bust out in any X ray test And then once they bend that part you’ll probably have a good three eights crack in the bend.
watching you guys in your element really is a treat. seeing mancub goofing off while theres hot wire being shot out at a mile a minute and the resulting weld still being a damn art piece brings new meaning to the word confidence, and jasons analysis and evaluation of welds and weld processes is both enlightening and fascinating. and you cant forget all the crew who work so hard at making videos like this seem effortless. keep up the good work guys!
Very interesting video. I use these exact same 5\8 carbon rods at my work place but freehand and although they are magic to do backgouges in very thick plates, i wish we'd have this kind of equipment sometimes because its a very hot process that makes a lot of smoke. It would be a dream to watch it from afar ; it's one of my favorite process. Keep up the good work!
Holy cow! The initial cut? That looked damn good! I've NEVER seen a flame cut that nice. I appreciate you guys! Thank you for sharing! Everything was awesome! But, see the few comments below? No matter how perfect you guys do, there will always be someone who just HAS to criticize your work, and if not the work, itself, then they want to tell you that you've misspoke. It's like you when you win an argument, online, but the only thing that the person can say to you, is that you've misspelled something. Whatever... I learn from you guys, and I want to say "Thank you". Take care!
For those asking about NDT inspection. Yes xray would pick up that inclusion, but I'd say depending on what code its inspected under its well within code. Most code allows an inch or better if slag inclusion in every 12 inches. Some are more stringent, some less stringent. Also depends on thickness of base material and and thickness as well as length of inclusion. Most defects including slag, porosity, lack of fusion, hollow bead, and even undercut on some codes have an allowance. Usually cracks are zero tolerance, accept in some codes star cracks under 1/16th are allowable. Like I said it varies with code and material thickness but most, if not all ( I'd have to check) allow some defects. Xray would pick it up, UT would pick it up, RTR would pick it up, Magnetic particle inspection would not, and Liquid penatrant would not. Hope I answer everyone questions.
I worked with a guy who could lay dualshield passes down so smooth and a final pass squared flush to the surface. Looked better than what the machine did here, which is actually pretty shocking to me. That guy was grade A talented.
You have covered so much in this video and you make it seem easy but I know from the gas cutting to setting up the welding machines it's no easy job but once it is gotten under the belt it is a beautiful skill to have and it will take you places around the world, it is a beautiful trade. ☺️👍🏼
Carbon arc gouging smells like me having a really bad day.. glad i haven't had to use it in a long time. Definitely love the flux core though. It's my top choice for most of my side jobs.
@@jordanlittle5391 Yep, definitely more convenient. And honestly, a lot of times i don't want the penetration of a good stick weld. Examples being thin wall tubing on a brush guard, almost any type of exhaust repair, chain link fencing repairs.. the list goes on. Anything structural, yeah I'm grabbing some 6010 rod and letting her rip! 7018 if it has to be pretty.
old school fix for the bow would be to use your track torch to flame shrink the opposite side from the prepped side. Less time no grinding dust or noise just takes a little skill!
Coming from a nonwelder, you certainly know how to explain things to a noob. I took shop in HS where we were introduced to MIG and TIG welding, but haven't touched anything since. For those who say manual labor is simple and anyone can jump right in without any education, if you don't know what you are doing you can quickly end up with 3rd degree burns or blind.
Wow , very nice my friend. Info was great. I was impressed with the carbon arc machine. I'm at retirement age so I can say welding machines have come along way. Great video thanks.
Ew why did you get coffee in the bathroom lol. Seriously though. When man cubs behind the wheel with these videos he’s a natural, professional and funny. His confidence sure rises when it’s just him
@@everlastgenerator im running the 350 ext at the shop, its had a little dirt get in the gas solenoid, probably from the hose, a bump and it shut off the gas, so it got cleaned via your service tech directions. from using a 1960's tig machine and then jumping on this was a little curve, but in 10 min i had figured it all out. had to play with it, 1/16" alum beads stacked them up on corner edge about 1/2" tall then started to stack them sideways 1/2". 3"long. no sag and a bright shiny pass every time. loved it.
That was a beautiful flame burn!!! And yes steel moves when being cut with flame, nature of the beast I guess. I know this was a demonstration weld/gouge but if on the real deal would you use ceramic backing or have you ever used it? When ceramic backing is used it eliminates the need for back-gouging with 100% weld. 2nd thing is that defect wouldn't fly welding on Navy ships where buts and seams are UT'd.
We don't weld ships but do allot of DOT work and they UT allot of it and no that would not have passed. And who's to say over 8ft that was the only one. Just caught it in the couple inches they cut out which means there was most likely more.
A.couple of things, First bevel was perfect example of how to utilize a track torch. Second not too bad but my concern is taking of overall width of the part in order to close a gap is almost never an option. If you are back gouging anyway filling a gap and maintaining your overall dimension is always a better option. Also as a structural steel fabrication project manager, watching all the unnecessary manhours used to close a gap you could have just welded was painful. The weldout and machine settings were superb.
Depending on what your building there's usually a tolerance your allowed to give a little leeway. Your right things almost never work 100% the way you'd like. We put in a small stringer in the bottom to close any gaps so there arnt any blow throughs. Then back gouging will take the stringer out and make sure you have fusion you need.
Exactly. I don't even run a landing on the verts because of just putting a seal pass in it to help prevent a blow-up. It can be a dirty down hand. You're gonna gouge it out. They also had the perfect chance to teach learning students what a key plate and bull pins are and how to use them. Plus the settings they had their wire at we're on the coldest side they could be and still work. Not sure what code he's talking about but API would fail that weld every time with that amount of slag inclusion.
We run fairly similar setup that you have here while building 89M wind towers from scratch. Take flat stock like so (except about 12'x36') put 15° bevels on all 4 sides. Roll them into a round ring. Put a small stringer (.045 GMAW) in the 12ft seam. Then it gets filled with 5/32" SAW. Which includes AC 1000 and DC 1000 power supplies. After inside filled in the outside is back gouged clean hopefully. Then same thing on outside with the SAW. Both welds are checked by quality, if they pass quality they get X-rayed by an ouside contractor. The ring must be re rolled due to the heat when welding. After they have been deemed completely round they get put on a line where I fit them together in 10 ring sections( towers are 89 meters tall you just can't build them in one section and expect to transport them ). There are 30 rings total so they are built In top, mid, base sections. We have a 15 ton ring cranes and two 45 ton section cranes that we use to move these rings and sections around. Its quite the process. Very cool tho to see someone else doing scaled back version of what I do all day. Btw we use .045" flux core wire when doing repairs on bad welds like lack of fusion or just garbage trapped in it. Also when installing the doors that go at the bottom of the base sections.
a few Years ago I bought a motorized hand-held Oxy-Acet torch...Koike Handy Auto....made some real nice cuts...especially using the magnetic track......they still make the Handy-Auto...and it's waaaay better.! Great for cutting plate...you know...like 3" thick....
Nice weld. Reason for the slag inclusion is because u did a weave on your root with flux core. If u only have fluxcore and not metal core a few more passes with smaller weld bead will lessen the chance of inclusion. Really dig the auto gouger.
Man I died a little inside when you told us how to fix the unevenness on the metal. I thought you were going to show us a better method than grinding XD
You guys are young and probably recover fast. I'd be in the hospital after inhaling those fumes for days. Amazing how you can inhale those toxins and be so energetic and ignore the health factor.
To stop plate from bowing run 2 tips one for the bevel and a straight tip at the outer edge taking a small strip of metal off.I used to make cutting edges for loaders etc.
Use to use .120 Flux core to weld grouser bars on dozers. Do a root pass on one side only with 7018 1/8" with good tacks on opposite side. Not 100% weld but good enough for grouser bars. Nice video! Before the was 1/4" 7018 rod.
Well, since I'm 73...I like the value of a couple or 3 nice sturdy metal sawhorses.....and keeps the flame cutting slag from blasting out that nice concrete floor...
I could have used this video a month ago if it was by hand and not with a track machine. The longest weld we had was 2ft so easy to do by hand. We only used 45 wire so it took a few more passes and instead of back gouging we ground it out. We had 30 degree bevels on both sides which I think hurt us in the long run but all welds passed in the long run.
Guys I just want to say excellent video. I’m glad you guys are out there showing us very impressive keep up the good work. Hope there’s a day that I can shake your guys hands
Simply beautiful oxy-acetylene cuts. The welds were terrific also. Very cool video. Silly question- why not simply buy a piece of material the finished size instead of welding two thinner pieces together?
Nice job. Sounds like you could go up a half a volt and get rid of some of the crackle. But what I really noticed is that you’ve got your gas line quick couplers on backwards. The female should be on the welder end of the hose so it’ll shut the gas flow off when disconnected.
Getting the moisture out? Do you know steel doesn't hold moisture? It's the hydro carbons that are in the gas that are condensing when they hit the cold steel.
Why don't buy a full plate without a weld?! Just a thought. PD: Or is it just a WELD demonstration? Which was impressive by the way. I know nothing about a weld but i totally liked.
Where i work here in Australia we make vibration screens, sometimes the sidewalls on these machines are so large that we have to weld two stock sized plates together to make one wall, we use an oxy/acet track cutter for the beveling but all the welding is still done by hand, it takes 3 days to produce one wall
@@Welddotcom just the real world my friend, unfortunately when you go into the real world you dont get all the bells and whistles you had when at tech school, sometimes you just have to do the old school way, which can be unfortunate but it teaches you the meaning of a hard day earnt and also to appreciate the way things were done, also makes you more humble at the end of the day
I have a couple questions 1. Is the automated system only able to do a 1G position? 2. What is the advantages of you butting plates and a back gouge versus doing a quarter inch gap.
Cool video but plate doesn’t hold moisture. When you’re using oxyacetylene, you’re not pulling moisture out of the plate. It’s part of the combustion process from the fuel gas. The reason it cuts better when you run the torch over it before cutting is because you’ve preheated the base metal. Not being a jerk and calling you out by any means just wanna make sure you’re giving your students the correct information
OK I get it this was a teaching moment, as I thought about the why aspect. So the only question I have is that inclusion I think he called it could all this weld have been x-rayed and would it see that spot imperfection in the weld?
Hypertherm pmx105 with a machine torch set up in gouging mode set up on the track welder. instead of the carbon arc would of been a good option as dont need the large generator and huge welder ect. You guys should do a video with it i think plasma gouging in very underutilized.
I have done this fluxcore welding for the last 15 years. I've done at least 20 of these test. You should have more drag angle on the torch and little bit more travel speed. You shouldn't let the puddle get too far ahead or it will leave slag pockets in the weld which is normally failed weld.
That slag inclusion if xray would have flunked. Anything over a 1/32 in size will flunk. I've had a lot of experience with welding at niles steel tank in niles Michigan in there specialty tank deviation building high pressure vessels all my weld were xray welds . Worked in the field as a tanky building crude oil tanks in Vernon ill at the end of the pipe line from Canada. Build 5 tanks with a crew the tanks were 300 feet across with floating roofs.
25 minutes what are the odds that the section that you cut for the.. coupon is the only section that has an inclusion 🧐🧐🧐🧐😂😂😂😂.. REALLY NO REALLY YOU GUYS ARE ACTUALLY MAKING ME CRY RIGHT NOW!!
i was looking for a video that covers core welding but i was not not sure if its called core welding in english because i am from austria and i id not think that it could be directly translated so i searched just for german videos and could not find one. THANK YOU

I like that these guys are super honest about their mistakes.
In all fairness, if they didn't admit their mistakes, the internet jackals would call them on it anyway.
No ones proud of a bad weld
I work in a ship yard building a Royal Navy vessel in Canada. I do this process every day for the ships outter seams. Full pen welds and then UT scans for quality assurance. Overhead, vertical and flat gouging with 3/8 gouging rods. The mouse holes are the trickest always be sure to stagger your tie ins and clean your welds from defects and youll pass everytime!
You want the key to the mouse hole😂

Trying building one
The amount of dross under is a travel speed issue

Both welds are checked by quality, if they pass quality they get X-rayed by an ouside contractor. The ring must be re rolled due to the heat when welding. After they have been deemed completely round they get put on a line where I fit them together in 10 ring sections( towers are 89 meters tall you just can't build them in one section and expect to transport them ). There are 30 rings total so they are built In top, mid, base sections. We have a 15 ton ring cranes and two 45 ton section cranes that we use to move these rings and sections around. Its quite the process. Very cool tho to see someone else doing scaled back version of what I do all day. Btw we use .045" flux core wire when doing repairs on bad welds like lack of fusion or just garbage trapped in it. Also when installing the doors that go at the bottom of the base sections.
a few Years ago I bought a motorized hand-held Oxy-Acet torch...Koike Handy Auto....made some real nice cuts...especially using the magnetic track......they still make the Handy-Auto...and it's waaaay better.! Great for cutting plate...you know...like 3" thick....
Nice weld. Reason for the slag inclusion is because u did a weave on your root with flux core. If u only have fluxcore and not metal core a few more passes with smaller weld bead will lessen the chance of inclusion. Really dig the auto gouger.
Man I died a little inside when you told us how to fix the unevenness on the metal. I thought you were going to show us a better method than grinding XD
Thanks for the hard work, I'm thankfull this was a great demonstration!!!
You guys are young and probably recover fast. I'd be in the hospital after inhaling those fumes for days. Amazing how you can inhale those toxins and be so energetic and ignore the health factor.
Kent, you nailed that switch flipping segment 🤘🔥
I would be very interested to see some more of Kent’s work in the future! 😂😂 Great vid!
😂😂😂 He's just getting started!
what a great video folks, I really enjoy it and learn a lot. Thanks
To stop plate from bowing run 2 tips one for the bevel and a straight tip at the outer edge taking a small strip of metal off.I used to make cutting edges for loaders etc.
Use to use .120 Flux core to weld grouser bars on dozers. Do a root pass on one side only with 7018 1/8" with good tacks on opposite side. Not 100% weld but good enough for grouser bars. Nice video! Before the was 1/4" 7018 rod.
Well, since I'm 73...I like the value of a couple or 3 nice sturdy metal sawhorses.....and keeps the flame cutting slag from blasting out that nice concrete floor...
I could have used this video a month ago if it was by hand and not with a track machine. The longest weld we had was 2ft so easy to do by hand. We only used 45 wire so it took a few more passes and instead of back gouging we ground it out. We had 30 degree bevels on both sides which I think hurt us in the long run but all welds passed in the long run.
40 years of welding man I still miss it but my health problems want let me anymore drives me crazy
6:46 hey halpert come here, it's time to shine 😂
Helper
Guys I just want to say excellent video. I’m glad you guys are out there showing us very impressive keep up the good work. Hope there’s a day that I can shake your guys hands
Thanks for watching. Hopefully one day soon we have an "open to the public" shop day
225 Ranger looks very potable, does it come with shoulder strap.
🤣
There has never been a potable welding machine. Not yet.
@@vermonty8813 Yup! Spelling matters!
🤣
😂😂😂🤫🤫🤫
Simply beautiful oxy-acetylene cuts. The welds were terrific also. Very cool video. Silly question- why not simply buy a piece of material the finished size instead of welding two thinner pieces together?
It's a demo. Normally those plates would be much wider.
@@Welddotcom You went to a lot of time, effort and expense. Many thanks.
Fun to watch. I welded pressure vessels in 1976. Neat stuff guys.👍👍👍👍👍👏🏻
Ditto mate I prepped cylinders for sub-arc 150 mm thick plate, sweating yer gonads off next too a furnace. Good old days.👍
We use innershield. It's awesome. No gas. We build Jackups .. fuel barges. Drydocks etc. No gas needed.
Nice job. Sounds like you could go up a half a volt and get rid of some of the crackle. But what I really noticed is that you’ve got your gas line quick couplers on backwards. The female should be on the welder end of the hose so it’ll shut the gas flow off when disconnected.
Welder is always👍 great job in this world
Getting the moisture out? Do you know steel doesn't hold moisture? It's the hydro carbons that are in the gas that are condensing when they hit the cold steel.
wow, cut like butter, smooth
Why don't buy a full plate without a weld?! Just a thought. PD: Or is it just a WELD demonstration? Which was impressive by the way. I know nothing about a weld but i totally liked.
Nice process!Both of u men are very humble!THANK S FOR THE VIDEO...
Hello I've been woundering wat type of welder/generator is good to start welding structure steel for the field!
A machine that is power to back gouge thats qutie
16:48 nothing feels better than that slag peel.
This was a great demonstration thank you
Where i work here in Australia we make vibration screens, sometimes the sidewalls on these machines are so large that we have to weld two stock sized plates together to make one wall, we use an oxy/acet track cutter for the beveling but all the welding is still done by hand, it takes 3 days to produce one wall
Gotta show the boss man this video... It would make your life so much easier
@@Welddotcom just the real world my friend, unfortunately when you go into the real world you dont get all the bells and whistles you had when at tech school, sometimes you just have to do the old school way, which can be unfortunate but it teaches you the meaning of a hard day earnt and also to appreciate the way things were done, also makes you more humble at the end of the day
Спасибо за интересное видео. Для обывателя выглядит фантастически.
so we are the backstops not applied before the back gouge and back fill take place? that heat would also cause it to banana peel backwards, right?
Really enjoyed that video. Great job!
Informative and joyful video. Great job for keeping us educated and entertained. Stay safe!
Thanks for watching
This is all we use for railroad freight car repairs. .045 with a backing plate.
I work freight car repair aswell. Unfortunately everything is stick welded by hand
@@chrisv3863 that is so time consuming. It took me a while to get used to the flux core. Only time it really sucks is working inside draft pockets.
That machine is a beast
Jason: I drove 3,500 miles with him staring at me. Yeah, and for some reason, he was staring at your BACK!
Thanks for teaching and showing us your new cool toys.
That coffee machine made me sad inside but the knife play at the end was pretty nice.
I've never ever slaged a weld with my knife??? More dramatic I guess
I have a couple questions 1. Is the automated system only able to do a 1G position? 2. What is the advantages of you butting plates and a back gouge versus doing a quarter inch gap.
That why the shipyard welds everything at once, i get it now. Great weld preparations thanks for sharing.
Cool video but plate doesn’t hold moisture. When you’re using oxyacetylene, you’re not pulling moisture out of the plate. It’s part of the combustion process from the fuel gas. The reason it cuts better when you run the torch over it before cutting is because you’ve preheated the base metal. Not being a jerk and calling you out by any means just wanna make sure you’re giving your students the correct information
OK I get it this was a teaching moment, as I thought about the why aspect. So the only question I have is that inclusion I think he called it could all this weld have been x-rayed and would it see that spot imperfection in the weld?
woulda been more impressed if you welded it by hand.. looms good though.. thanks for the tip with the u hangers or whatever they are called.
Do you think that equipment is a bit too expensive for a hobbiest to get?
If you're a we'll off hobbyist maybe lol
Hypertherm pmx105 with a machine torch set up in gouging mode set up on the track welder. instead of the carbon arc would of been a good option as dont need the large generator and huge welder ect. You guys should do a video with it i think plasma gouging in very underutilized.
I have done this fluxcore welding for the last 15 years. I've done at least 20 of these test. You should have more drag angle on the torch and little bit more travel speed. You shouldn't let the puddle get too far ahead or it will leave slag pockets in the weld which is normally failed weld.
That peel is enough to make a grown man cream
You should see the comments on some of the other platforms. Enough to make you shake your head 😂
🤮
Sauls Rappin wow! You’re an easy date.
So gay dude
Looks like a tasty slag tortilla chip. Needs some salsa!
The cut I so clean i really need like that machine it agreat vedio man thanks
Used to do plates like that with Sub-arc
That slag inclusion if xray would have flunked. Anything over a 1/32 in size will flunk. I've had a lot of experience with welding at niles steel tank in niles Michigan in there specialty tank deviation building high pressure vessels all my weld were xray welds . Worked in the field as a tanky building crude oil tanks in Vernon ill at the end of the pipe line from Canada. Build 5 tanks with a crew the tanks were 300 feet across with floating roofs.
Nice job standing in the fume plume
25 minutes what are the odds that the section that you cut for the.. coupon is the only section that has an inclusion 🧐🧐🧐🧐😂😂😂😂.. REALLY NO REALLY YOU GUYS ARE ACTUALLY MAKING ME CRY RIGHT NOW!!
Talk about having some great equipment...
i would have added a ventilator though to get rid of the welding fumes.
I’m kinda a newbie to welding. Why not just cut the metal to the size you wanted? Or is this just demonstration purpose?
I love watching this stuff. Great vid.
Thanks sir nies walding😊😊😊😊😊
Verygood, i can learn from this vidieo, thankyou
What a great video.those welds look amazing
No.shit it was all robotic
Very good job
i was looking for a video that covers core welding but i was not not sure if its called core welding in english because i am from austria and i id not think that it could be directly translated so i searched just for german videos and could not find one. THANK YOU
