As a Boilermaker I've seen some bad fit ups. You try everything to get it the best you can. Five or six years ago me and my welding partner had a heavy walled 8" supply line. We done everything we was aloud to do, to get a good fit. We had the weld tech, Gf and the plant man over the Boiler come a look at it. After awhile they said weld it. The weld was in the 6g position, the bevels matched up good but we had tight 3/32 gap on bottom and a 3/8 gap on top. It was a interesting fun weld to tig the root pass in it. Out in the field sometimes you just get bad fit ups. Very nicely done root passing the fit up in this video.
A 3/8 gap on the top!!! Holy cow!! That must have been quite a pass
I am a skilled welder, i need a job does the company still need labor. Sign me up.

I have several friends that local 69 in Michigan
When he said "we wouldn't accept this in the field" I laughed and laughed in boilermaker
Thank you for this!
What a couple of pansies!
I was always told by the other WELDERS (let alone what the fitters said) that if I couldn’t take something like this and roll with it on the regular, then I just wasn’t a welder, and to go look for work pushing a broom.
Yeah I walk up to shit like this all the time(usually on stainless) and the fitters are just like "what's wrong?"
Yeah pretty disrespectful. But u better know how to weld that shit.
I coughed in tankie
Laughed in chiller retrofit hahaha
Glad this kind of video came out.good info. I encounter bad fit ups on pipelines/oilfield locations all the time. Not much we can do but just to "WELD IT BIG BOY"! and tell them xray idiots they can xray deez nutz.
Amen
This might be my favorite comment of all time
Love the videos I’m just starting to get into welding and y’all help me so much
Former RT technician... I saw the title and my inspector sense started tingling. I had to watch. Great work, thanks for the vid.
You guys are the people that keep America open. Great video!!
As a young amateur welder i learned quite a bit from this video, great techniques to practice and tryout. Thank you guys for your help in such a competitive market
if you get to work on oil and gas pipe lines that set up is not acceptable, so do not accept the set up, the bore of the pipe is stepped and would show on XRAY of the weld, that is why we have ASME pipe standard s world wide, good weld ok but not for ASME standard
@Justice
the bore of the pipe and tube turn (fitting) is badly stepped This will cause lack of penetration etc and would fail xray inspection ,may be ok for some non pressure work but not for Petro/Chemical work
In my experience I’ve come to love those situations. It makes you a much better welder facing a nice challenge every once in a while.
I'm a fabricator not a pipe welder but I agree, I love a challenging project, makes you better in the end. But God danm it can make for some frustrating days...
@@MikeP350 You ain’t kidding. I earn my pay going underneath 60+ Y/O buildings on steam and Hot Water. However it’s the really really bad ones that make you a better welder in the shop and when you have easy access to your weld.
Makes it worse if you've got someone wanting to breathe down your neck. Patience gets really damn thin.
sack the fabricator, bore of the pipe is off , burst the tacks and reset the pipe butt
Facts
Bless It’s like watching an artist at work. Really nice job. Thanks 😊
Not that bad. I have closed up gaps up to 3/8" using a stick welder. Vertical ups. 7018 DC reverse. Having a well equipped shop with a cement floor is a bonus. I spent most of my time with a Miller 4 G doing that kind of work in a plowed field. Made for some interesting days. Have a good one and stay safe.
Dope video. We need more videos like this.. just men working lol doing things we normally don’t see and take for granted.. plus i like the small goofy things y’all did..
I took a pipe welding course in 2001, we did all the same techniques shown in your video, 'walking the cup' in the 6G was my favourite. Our teacher was from the pipefitters union in Ontario. I learned alot but never joined the pipefitters union, too much travel and we were having our second child. I have been looking for a multi process welder to work with at home, they are getting pricey. Good video, thanks.
As a former welder, This is excellent practice and instruction , because its not about whether you get a bad fit up but WHEN??...and the pusher says "Ehhhh!!...I know it's bad fellas but I don't have the time or budget to rework the fit, make it happen fellas that's why I hired you guys, I know you can handle it" as he slaps you both on the back walking away muttering he''ll check back later!!....And there you are out in the field glad that you went thru a training session like this to confidently proceed to make "FUBAR" HAPPEN and build that reputation for dependable professionalism that can be counted on!!....Great video and technique Fellas!!....thx for sharing!!👍
I'm also a professional 6G welder... Love to see it.. This is a part of our job. Nice weld bro.
whats the pay like?
Andreas Sure made that Cap out look really great considering the constantly changing amount of fill depth as he went around the Pipe.
Beautiful Work.
He's on jackstands, in a nice clean shop, welding 5" or 6" carbon steel pipe. And his fit up, while not right, ain't nothing that a real welder would cry about as much as they did in the beginning in a damn video about a bad fit up.
This not only is the easiest material. But it's the easiest size. In the easiest position. The easiest wall thickness. In the easiest place to weld. All done with top notch equipment, in a controlled setting.
Settle down .
Thanks for the video lesson. That was a lot of tedious work to just give us an example and I appreciate it and the commentary on the temp and wire size also. 👍
Another great job. Could you please explain how to use measurement tools that you applied before welding?
nicely done, as u say sometimes u just gotta get it done even if u normally refuse such gigs like this u do come across em from time to time.
🔥Nice work guys! 👊
Right on! Thanks for the info!
@5:48 nice tungsten inclusion there 👍
Excellent demo, great close ups
True pro welder...Great job and looks better then any welds Ive seen....
Gracias amigo muy bueno aprendí mucho de ti y resolví algunas dudas que tenía gracias. Awesome!! 👌 .. thanks buddy..
my welding teacher in the 10th grade was a do it right or dont do it at all type. he made us learn to gas weld with hand feeding the wire, like tig, but with gas. then we had to learn to stick weld, them mig. tig was last. i knew before then, i would make my living by working with metal. nice job, thank u for ur time sir.
Your welding skills are extraordinary 👍😎
Great tips! Thx!
2 bead cap will help hide the hi-lo from the inspector too. Just little stuff like that will help get you by in a jam when your fitter is a mullet.
O
If there was an inspector.. it shouldnt of got this far.. hahaha
Hide stuff like that is not the right way to handle it. Show it the people in charge bevor you start work and when they ask to proced have a note from them that they actually wantet it that way fixed.
Because when it blows up, (worst case scenario) at least it doesnt blow up in your face and people in charge can not say they did not know about it. 🧐
@@1AngryPanda Pretty much this. Cover your ass so it doesn't fall onto you later as management loves to play blame games. Hiding stuff just puts the liability on yourself and can be a good way to be finding a new job in short order.
@@corail53 or even worse, find yourself looking out of a window with some bars in front.
@@1AngryPanda you boys are right, its time and money to the company but its your reputation and future for you. Dont make other peoples problems your problem.
Excellent video . Dude is an artist . Impressive
amazing work.
So satisfying watching him walk the cup
Representing the 915!! Hell yeah🔥🔥
Looks great bro I wish I had the equipment in my garage I would do this nonstop till I mastered every type of welding except underwater welding of course. Damn I'm soooo into this as for a living and hobby.
When I was a welder at a place that made burner cells for power plants I always got in arguments with the fitters about joints having excessive hi/lo points and bad bevel’s, But I always made it work . Was never happy about it tho
I was a pipe welder in an offshore module pipe shop doing cunifer, stainless, carbon and other materials mainly working for bp, shell and agip, even though the pipe fitting was qc it wasn’t all that good most of the time, a lot of the work was 100% bomb, the inspectors used to be ok if there was a miss match apart from agip inspectors who were very strict even when they could see the issues, I saw the light after 8 years and joined the U.K. fire service and just retired after 28 years service, I still watch pipe welding videos on TH-cam though who knows I might try and get back into it😎😎😎😎
Looks great bro
Beautiful job
Nice work
I know you aced it. You know you aced it. Respect.
Amazing!
From start to finish, how long did it take to weld one of the joints?
That's Amazing!
nice close up video of the welding. what camera are you using? can you share more?
Thanks you MR good job ❤
I don't weld. Always wanted to learn. I watch so many welding videos... This one was extremely in captivating.
This was pure beauty and wisdom. Love this video!
Damn great job!👍👍👍
That arc out is crisp
Bad fit up is unavoidable. If you have been in the field long enough you will find some crazy stuff. I’ve seen quite a few of these “professional rig welders” do some really shitty work but they have a damn nice rig. Don’t let that intimidate you if you’re just starting out. It’s not the equipment as much as the person.
Exelente trabajo Nice
Now that man is a tig hand 💪🏽
Great welding 👌
Nice job good looking welds
Thank you.
Well done
Awesome 6g weld. Neat beading. Respect
Not 6g
So perfect 👍
Are you welding multiple times the same line while increasing the amps each time ? to fill the hole ?
looks good.
What torch are you guys using?
Great skill
Mantap,,, good job
The last pass is so gorgeous 🤤
When something that difficult is made to look so easy you know that there is great skill behind that gun...great job making it look effortless
How much cool time do you leave between passes?
Y
Thanks for the great video 👌
Gran trabajo viejo los felicito .una pregunta.,cuanto gana un soldador en usa ?
This guy got the skills to pay the bills baby!
Excellent demonstration and explanation. I had never considered how helpful it would be for penetration to feather down the edges of a tack-weld - it makes perfect sense and I'll add it to my list of processes to try. One question, what's the thickness of the wall on the pipes being welded please?
They said it’s schedule 40 but actual wall thickness depends on pipe size. If this is 8 inch pipe the wall will be 8.18mm thick. 10 inch pipe would be 9.4mm thick. This can also vary slightly by manufacturer. I hope this helps.
@@tolittletime Very helpful, thank you. It's hard to guestimate the size of the diameter by looking at a video made with a hand-held camera. It appears from your info that these two sizes of pipe have wall thickness somewhere in the 5/16"+ to 3/8" range.
@@brucebear1 He said 6" sch 40 so the wall thickness would just be .280"
thats impressive weld sir
Beautiful 😄😎🔥🔥👌
Super 🔥🔥🔥
I'm just learning how to TIG weld and I believe you just showed me why my verticals have been looking like trash.
Really nice welds...and welder yoga.
Esos guantes aguantan buena temperatura???
If only I had some Custom Metal Fab guys that could Weld even just a lil like that, run a press, run a Bridgeport/Mill, a lathe, and a watertable like me and my pops man sky's the limit where I'm at I just need people that wanna learn or know what they're doing down In white house TN lol awesome video my man 💪
Now that, looks like the stuff I get given to weld...
Except yours is cleaned.
I remember welding a pretty worse fit where one side had a gap of 2mm and the other side was more than 15mm
All was welded with 6mm elektrods with a smaw welder
The man who was doing the cutting did a terrible job using an astilin* torch on 8insh round tubes
You're trying to say you were stick welding pipe roots with 6mm rods?
Biggest but of bullshit ive read for a while, congratulations 😄😄
Stupid question....whats the reason you dont use mig on these welds? im not a pro welder, just wondering
We gets all kinds of awful orders for things that don't fit together at all where I work, you get really good at dealing with it after enough time XD
Watching this guy weld makes me wanna weld something up
I’m still in school for welding, my instructor tells me not to change the temp from root to hot, is that just something to do when your learning?
Eh learn how you’ll wed in field I run loose 1/8” gap with 1/8” wire about 95-100 amps and on hot pad crank up to about 135 ride bevels and feed wire in middle so it doesn’t suck back and after hot pass turn up to about 165-170 until cap. Lots of folks run a whole lot hotter on all steps but I prefer my method for me, heat is your friends with welding just remember the hotter it is the faster you must go for the most part
Also practice freehand and walking on pipe you won’t always one in a spot in the field where you can walk to cup on any position so good to be decent with both
@@curt714 okay thanks for the advice!
This might be a dumb question, but I want to know, what happens if you dont do it right? Does it have that much pressure inside that pipe line or with time it will break ? Can anyone explain it please, thank you
For the welder, the only issue is that it doesn't pass inspection. For the line, when you have abrupt transitions in interior diameter it can create both turbulence in the line, and premature wear, as the product will constantly "catch" on the sharp edges and wear it away faster.
Hello, I don't know what quality of solder you need. do you have problems of welding pollution with the corundum of the grinder disc?
Won't that area be prone to erosion from product hitting that lip?
That was a beautiful job you did there I have a nice welding machine but it wouldn’t be big enough I have a dynasty to 10 DX when you start getting up at 175 amp area the duty cycle wouldn’t be enough to do a job like that but I use it for little things anyhow this is a Jim mungai from Kennerdell Pennsylvania
I'm wondering what it looks like on the inside. What kind of material flows would flow through the pipe and what kind of inclusions or protuberances if any are on the inside of the pipe. Longevity of the pipe depends on how the weld turned out inside.
So what was actually done differently for this weld? I know F/A so to me it just looked like a standard welding process but the pipes are misaligned, how/why does that affect how you weld it? How did you deviate from a "normal" weld here?
They just complained for the sake of content
That cap is weld candy
buen trabajo nene
I build tanks some times that last joint in a heating coil ain't quite right but no one knows after adjusting a cut angle or two with a zip disc sucks seeing tie ins all high low like that on piping jobs glad I don't see it at my job
hoping next video its done using stick welding, same situation bad fit & all, just curious if its doable using stick, 😁
Why do you use 90 amp for the root and 175 for fillers?
"worlds worst fit up" you should have seen me when i decided to undertake my own exhaust work LOL
I want to see root pass inside. Can i ?
When I welded we made anhydrous tankers, and all fit up had to be flush since they were under pressure and and human weld was ground out to after covered with a machines hot weld all except my hot welds for the final seam. The proper fit up would be required not for the looks but the safety. We took pride in our trailers and loved the job wish the compensation would of been there.
Reasons you never put the flange on until after you have the pipe all welded out. Just an FYI for young fitter/welders out there. Good job dealing with a shit situation though.
Is there a reason to Tig this istead of stick welding it? New welder here, just wanna know the thinking behind it
Better control for root pass
I can still remember in 1966 that the welding rods being used by our military that are made out of 20% chromium, 20% nickel, 3% tungsten, 8% molybdenum, 5% tantalum, 5% niobium, 3% ferro-mischmetal rare earths alloy mixture, 1% carbon, .25% boron, 3% zirconium, 2% cobalt, and 29.75% iron. We use them to weld military grade alloys for various vehicles and equipments. And that also includes nuclear reactor components not exposed to radiation after the 2sd heat exchanger engineering section using inert beryllium fluoride salts.
This is why I like to make all my cuts and weld on the elbows first, then set everything in the hangers and mate it all up in the air with clamps to avoid problems like this. in the last 10 years lasers help a lot to avoid problems like this.
How long did it take you???
