Another great video Bob, showing real world problems and solutions. No fuss, no drama, shit happens, work out what went wrong, fix the problem and move on. That is why we watch Bob, to learn more.
Nice to see you're demonstrating some real world procedures you would run into in the heavy equipment repair field. Boom repair, cutting out bed liners, crack repair pin and bushing removal and so on. PPE is definitely your friend ! Definitely make a good series of training videos. Thanks.
My buddies at Electric Boat say they don't allow air arcing unless you're in full kevlar with an air supply. Keep your neck and your ears covered and you'll be fine!
@@HogsHeadStudios yup full face respirator neck/ arm kevlar plus full body leathers double hearing. Doing that this summer in the 90-100 degree heat really made reevaluate what I'm doing with my life
i had a job at 18 doing just this. kaiser steel/napa pipe... repairing welds that the robot subarc machine had messed up on the seem of 48 inch pipe. i had to air arc out the weld and stick weld and blend it back. it was a terrible job! especially air arcing inside the pipe and having all the sparks sneak their way in anywhere they could. you are a wonderfull teacher, Bob! please keep it up
I love air arcing. Everyone else in the shop hates it when I air arc, but I love it. Bob, you know you can use a grinder more than once? You don't have to throw it away and get a new one every time.
idriwzrd lol I told my buddy you have to throw them out ever time he uses one. Funnier than hell watching him grinding throwing it away and putting a new one in.
I built tugboats for 10 years, used to do alot of arcing. Weld first side of butt, arc the backside to achieve full penetration. We were running .045 and .052 Lincoln ultracore. I was real proficient at the process.
I had the same issue 4 years ago, no carbon arc, only Carbide Burs and Grinders, I was there for a long time. I was so upset that I it threw it all away and started over with all new rods and welding cables. I am glad that I am not the only one that has problems.
That was the very best shot of a stick weld pool and the motion needed on the weld traverse that I have seen in months of watching welding videos - excellent. Must look at the arc gouging video as well although as a hobby welder I doubt I will ever use it.
Bob, we used to call it air-arcing years ago. I started out pimping for a welder air-arcing, and I Learned quick you cover up all exposed skin. My neck was about 2nd degree burned because I didn’t have a leather protector attached to my hood and didn’t think to wrap my neck. My welder just laughed the next day and said, we’ll kid you learned something very important your first day and probably will never forget to cover up. And I didn’t.
Yep. Worked in a power plant as a welder for 38 years. Replaced hundreds of socket weld valves by gouging the weld off. Mostly P-22 or P-11 and ofcouse A-106. Good comments from some that haven't seen a weld repair done using a arc gouger. Bet they would really like to see a weld removed from a socket weld. Just an idea.
Just browsing for videos on making batteries using 26650 cells, came up on this one...while thinking of alternatives. Being a non-welder I could even easily grasp the problem and the repair ..and it was interesting. Appreciate your efforts.
Gouging used to be part of the welding test at the old shop I worked in back in the 80's. It was used extensively for repairs after critical welds were nd tested and inspected.
Another great post Bob! Great job cameraman! The cutting part of the trades is important and requires much skill. It doesn't get the attention that it deserves. Please do some videos on the oxygen/fuel scarfing tips. Thanks, Jim.
Yup, been there done that, all the way up to 30 feet, sometimes porosity hides but UT scanner can always find it, glad to see I'm not alone. I usually have good luck with 71T for repair.
Great vid first one of yours I’ve seen. Your casual manner of speech caught me right away(reminded me of a channel called AvE) and your talents ( reminded me of I C Weld) two great channels now combined in one great channel. Subscribed as soon as I heard “blow and go, let’s get to it”. Thank you.
Just yesterday, I was just about to watch your other posts of arc gouging during one of my TH-cam marathoning opportunities, but got distracted/interrupted & never got around to watching any of them again. After watching this one just now, which was REALLY COOL (hot) to observe, I’m DEFINITELY going to go watch the rest rt now. I’ve never seen or heard about arc gouging before, at least other than reading your post titles of those other arc gouging vids on your channel. Thanks for sharing that Mr. Moffatt! Aloha
Building barges for Conrad industries and Halllimar ship yard I was all ways the gauger. I loved it. And was very good at it. Talk about hundreds of feet of gauging.
The only things I enjoy more than arc gouging is thermal lancing and the rest isn't family friendly. Also that's the quietest arc gouging I've ever heard.
A better technic is to gouge away from yourself looking behind the arc. Try it, will never look back. You don't blind yourself and see clearly a crack or whatever else you are removing as well as where you go. So you see how much you remove as you go. No overgouging. But 9 out of 10 guys do as they would push the gun. Ok for a foot or two in a while but 'no bueno' for a shift of gouging;)
I have some hard to access welds to gouge out and redo, no carbon rods (I am at sea), grinding is not an option (inside corner), 5mm thick L bar to samish L bar... Should I just spatter them out with a bare rod?
The resend you have that problem is because you air arc in the wrong direction plus your not to look at arc flash and the Slag look behind the carbon rod. I'd used to air arc 220 feet in my 8 hours shift and that was in a ship yard
I fucked up and made two gouges. I gouged a v basically when I did an open butt and I was back gouging and I made a v. So I am trying to see how to fill in a gouge perfectly
Hey Bob, Hey Camera guy! Would either of you gentlemen please tell me if the clarity of the close up arc shots is what it looks like through the ESAB hemet? I have an old Miller Elite hood where everything is green, but I'm looking for a new " true color" kind of helmet. So far the Viking is the best I have tried, but of course I haven't had access to try an ESAB. Thanks in advance and showing the gouging videos! ✌
I had a similar problem on some quarter inch steel I was MIG welding. Everything looked good until the last half of the run is it look just like yours did. I cut it out but got the same thing on the reweld. I even went as far as taking it to the mill and cut out everything touched by that weld and still got the same. Bob, what's up with that?
Check your nozzle. Not just for spatter for for fit. As a nozzle gets hot, it can expand and cause gas leakage. Happened to me when I swapped from a brass nozzle to a copper one.
interesting process that carbon arc gouging,,, a bit off subject but,,, can you recommend a welding helmet for approx. $200? and thanks for all the great videos.
ok - i am doing something wrong or just misunderstanding. @6:19 - the split screen on the right is this how you Bob see through your shield or is this the camera....because I never have this clarity - would love to....but don't
A huge part of that is the quality of the lens. Esab and Optrel use very good glass. I've looked through Lincolns and Millers and all I've seen is green. My Optrel is clear and I can see the varieties of colours. I've been told that the gold lens for pipeliners accomplishes the same thing.
A while back my welding instructor and I were building a trailer and he was dead set that that was the case for one of his mig welds. Turns out the welder's fan was blowing away the shielding gas
Its “bueno” you are getting bilingual. I have never seen in person arc gouging, surprises me that it looks like you were able to strip the welding material (porous) but not much of the base metal. Even the rod looks like getting pointed to “match” the shape of the base corner. How deep is the arc melting material from the the tip of the rod? And, should the operator expect some force or contact feeling?
There is a feel to gouging, but it's pretty dull compared to even something like 6010--which means most newbies take WAY more material away than they need to.
When I'm gouging the sparks are flying 20 feet out, it seems you were just pushing a puddle in front of your carbon, perhaps your air nozzle wasn't properly aligned or your air pressure was too low.
@@Welddotcom Fair enough, I spent weeks gouging an annular plate off of a giant oil tank at a refinery and it looked to me in your video the air was blowing behind the carbon instead of in front of it, that makes a big difference because the carbon doesn't like reacting with slag which stops the arc causing lots of starts and stops. Thanks for the videos.
Yes, you could use a plasma cutter if you had it set up for gouging. Check out weld.com's video on plasma gouging. You could also oxy acetylene gouge it as well.
I was wondering the same thing as not everyone has access to a carbon arc set up, but many people now have access to a plasma cutter. Perhaps Bob could offer an opinion or even make a video on the subject?
@@markfryer9880 That and I'm pretty impressed with what the electronics in modern welding equipment can do. Heck, look at the size of old, limited TIG machines! I asked because my old Firepower FP18 can't cut aluminum, but I can gouge textures. With higher-budget gear, I expect it's common somewhere. I'd love to see Bob do an episode on this to see how it's done and why/when. It's the decision-making and seeing Bob pull something bad out of the ditch, so to speak, that I most enjoy here.
Using very small dia. copper clad carbon rod you can do very small cut outs with a 250 dc welder. It would even kick my SA 200`s butt on 5/16" rod. For me ideally it was a 400 to 600 amp dcrp machine and using a 3/8"rod to do some heavier and larger gouging and scarfing work. Most times I preferred to use my oxy/acetylene torch with a scarfing tip.
I work on heavy equipment i got a syncowave goes to 300 amps and wired to 3 phase 480 volts (100% dutycycle) I do a lot of cutting edges it takes ever amp to gouge using a 5/16 rod on 5/8 blades on dozers
Do the automatic welders run coolant through them .I'm not actually very sure but the kemppi units we used to use if they ran low on antifreeze it caused porous welds .
If it was a everlast welder I have had the gas solenoid stick in mine a few times it should b open should b working but it's not stop welding start again and it works
Yea right! just because it looks like it was run without gas doesn't mean it was, I mean he said the gas was on, right? lol maybe someone backed the regulator off to save it some wear or make it safe.
Bob is looking at the wrong side off the gauging rod😂. You dont see shit on the front side. Just lava. No clue whatsoever about depth or finding the separation line🥴. Always look on the clean side, behind the rod. Trust me the onley thing i do is gauging. For over 22 years now.

Nice !!!!!! Carbon Arc Gouging , Now How Cool Is That ? Triple Thumbs Up
I see you three times and add you two more plus two big toes
Wow gouging looks so different looking at it from “down wind”. I don’t think I’ve ever seen it from that angle and I do a lot of it.
Love that sound. Good way to clean up and have fun at the same time.
That smile-cut timing was art. Good stuff.

Bob, another great lesson video. CAn you share what the settings were for the carbon arc?
if you use a sharper angle you can reduce the amount of slag clean up
Thanks.
Spay a little splatter spray before you gouge will help with slag and overall cleanup
@@NoizyBearBearOfficial yeah that is exactly what it is
We have the spray, but mostly we use the powder zinc oxide that you mix with water and paint on. Works great but ends up getting all over you.
Wow Bob ain't never see metal eating ant's, what caused it didn't hear what happened good video on this thumbs up.
When its so loud the camera cant pick it up lmao

Could b junk in the steel I had that problem before some cheap steel gets contaminated with lead and aluminum welds like shit
Can you run air arc off an inverter stick welder
The 200 dv seems to be a dam good machine. Cant weight to get mine
It's one of our favorite machines Everlast makes. Reliable and excellent arc characteristics.
Something interfered with the gas flow. And it may have just been a piece of dirt that interfered with the gas valve or something for a short time.
👍🏽 good stuff
that happens with me on plasma cut parts some times when you stop and restart no porisity
interesting process that carbon arc gouging,,, a bit off subject but,,, can you recommend a welding helmet for approx. $200?

i'll subscribe the day you get back in front of the camera, Bob.
Bueno then cuts to his face lmao 4:35
Your cup was probably blocking the orifices where the gas dispenses shielding your weld pool .

Great video, interesting concept, of gouging! I would have use the oxy torch with a fine cutting tip and steady hand!
When I'm gouging the sparks are flying 20 feet out, it seems you were just pushing a puddle in front of your carbon, perhaps your air nozzle wasn't properly aligned or your air pressure was too low.
We have a shroud that catches the sparks. I can assure you that without it they'd be flying 10+ feet.

How big of a compressor do you need to gouge?
just blow really hard
also look at the CFM requirement on the torch it will tell you what amount of air you need.
May I ask what machine made that porosity atrocity?
The video is out there I cant rember the video name the welder was a everlast cant rember model num
The gas solenoid stuck shut somehow?
Happens once a month on my everlast
How big a machine do you need to run a carbon arc rig?
Using very small dia. copper clad carbon rod you can do very small cut outs with a 250 dc welder. It would even kick my SA 200`s butt on 5/16" rod.

Or it was a preplaned designed flaw for the video!

4:42 dat wtf moment. :D
More air and ucould blow that weld out of there in one pass and veryclean
Hmmm. Wonder if that would be good for opening a safe......
It'd be great for opening it... Not so much for what was inside it.
I've done it a couple times. You have to cut it very thin without cutting through then use a cutting wheel
Muito bom
thumbs up. bb
Helps to turn your gas on
mike shortridge he said it was on
Yea right! just because it looks like it was run without gas doesn't mean it was, I mean he said the gas was on, right? lol maybe someone backed the regulator off to save it some wear or make it safe.
