Great video, very well done. There are couple things I would like to add.
The arrow is on the overlay so you don't lay it on the pipe up side down. The RT technician should be able to give you some idea of the depth and size of the weld defect.
Since the most common location of defects is in the start of the weld welders should always try to stagger their starts and stops. If you are making a weld repair such as this it's difficult to alter your start point. In a case such as this you can tack a strip of flat bar (tab) to the pipe just below the excavation strike off on this tab and carry the weld in to the repair. Once you are close to finishing cut the tab off and complete the repair. Nothing worse than having the repair fail due to cluster porosity at the start location. Of course a welder should always strike off in the weld zone and move the electrode to the weld start position to warm the electrode up before actually forming a bead but with repeated beads in a concentrated area there is greater risk of defects such as porosity and inclusions being concentrated from all starts.
Hahahahaha..... It’s the “fuck x-ray” on the welding mask that did it for me, lol, great job on the simulation repair👍🏿
im a welder and i just wanna say you guys and gals at weldtube are true professionals who take pride in your work.
Awesome vid. Thanks for this, I learned how to repair a pipe weld, seriously having been certified on 6g my instructors were all about doing it right the first time... And not having to repair your work so they didn't spend much time on this sort of thing. They basically taught us to just grind and reweld. But this is good information thank guys😁👍🇺🇲👍😁
Yeah!
Very good lesson ..thanks..very instructional..reading an x-ray and how to apply it!!! Also learning how to repair it ...with techniques from the grinder and how to weld it up... Will use this in my welding class wvncc. Thank you!!
Helpful Video, I really appreciate the time and effort it took in making it. Thanks for spreading knowledge.
Thanks for a GREAT video! I didn’t know to properly repair inclusions in pipe! I damn sure won’t forget this!
Nicely done James 👍great video team 😀
Great tips, another knowledge i gain from you👍👍👍
First class job. Great work.
Good video as always, this is a very useful video since most people never truly learn to repair X-rays the first time. And as everyone else has stated where them weld tube stickers
Thanks for this. Great job man
Just what I was searching for, thanks =)
excellent video thank you very much for sharing it friend!
Sometimes I feel as tho I can get ache eye just by watching people weld in their vids😂😂😂😅
Something really important when you're preparing the section for repair with your grinder. Pay attention to how he blended the cut section back to the surface of the cap with his grinder - nice and gradual slope. You don't want any deep cuts that aren't well blended with the grinder, that can lead to lack of fusion right in the deep corners of your cut area and you'll have another failure on the x-ray.
Good video... helps a lot👌
Good job maked by good worker !
Yup, real nice example. Thanks
Nice bro, gracias por compartir tu conocimiento saludos desde chile
Good job man
Well done.
Man this was a dope ass video man
Verry good. Thank's
This is a great video. As an x ray guy, they may reshoot it to see if you got it out. Sometimes you PT or MT it as well. 80% of the time, the welder is going to be told to find it, fix it, and weld it up. Then I will shoot it again and hopefully it passes. So for any of the young bucks out there making weld repairs, good luck . Welds go down . You weld long enough you will fail something. It doesn’t mean you are a bad welder. Some shit just happen and thats all. Learn from it. I just fucked up two shots last night. Then I had to go back and reshoot it again. Everyone fucks up.
Good information dear👍
I can tell your no amateur. Wow really know your stuff great job
Nice job clean.
Very nice
Muito bom!
Maravilha!
Grande Abraço!
Brasil!
Nice video
Who’s badass lifted red f150 ??? Clean truck
Finishing super
Thanks
Nice!
Thanks, good stuff.So, what is likely the cause of leaving a slag inclusion like that? Poor technique, wrong settings, prep? What is the usual culprit?
Ut has its benefits over rt in some cases because we can tell the welder the exact depth, length, and location marking it out clearly on the pipe . You can’t get depth with RT Like you can with UT. After the weld is excavated we can use MT to check for some remaining defects such as the remaining ends of a crack which can’t be seen easily by the naked eye . Great video btw
Why weld
there need to use the marker for the welding repair?
What happened with the one video about the whip and pause technique Mr Abraham did? Can't find it anymore
@@weldtube I appreciate it. Stay gold!
Any repair I’ve ever had too do with stick every run throughout the repair every run needed I always burn a fresh rod, I’m a strong believer in fresh rod clean run
Y’all should make a video on taking measurement on Ibeam, angle iron and pipe using a tape measure
Pythagorean theory right !
Great job dawg
Yea in a turnaround where its get it get it they just tell you grind it open then pt root and pt final then xray or paut
Gotta know how to run a grinder. Knowing how to repair pipe welds is very important
Does anyone use a die grinder with carbide cutters?They chop out a lot of metal and no sparks.
Clunk49 thats not ideal for pipe weld repairs
🔥🔥
I like how his weld failed Xray and he has a sticker on his welding hood that says “fuckXray”. Should’ve left the Xray tech a crisp $100 bill taped to the pipe.
Thought I was the only one who noticed🤣🤣
Why he would leave money for ? To compensate the hassle ?
@@srjr2531 it’s an inside joke with the welders and X-ray guys. Leave money for the X-ray tech to not fail his weld.
@@tonymedina922 lmaoooo nice I have yet to take a X-ray test , now knowing this when I go test I will take some dollaz lol
Why the welder need to use the marker for the welding repair?
🔥
What is that counter on the wall? What is it countdown for?
how did you noticed that? regards
@@stalopix I like know things
@@tomekpawowski2692 nobody answered your question? i am also curious, best regards from Greece.
Noup my figure is that this counter is measuring time to end of the year
@@tomekpawowski2692 seems logical, only video upload date must be much different of date recorded. I do agree.
Better to use a tiger disk to take down the cap
QC also should’ve been able to give a depth on the indication, at least if they do UT
A good x-ray tech should be able to get you close. That don’t mean all of them though, chased some stuff all the way down that wasn’t there, such as: hi/lo called lof on the bead, undercut on stringer cap (in between stringers) called undercut or lof on the bead; I’ve had one come back to say there were like 7 bad ones from burn thru and I was running hots that day 🤦🏻♂️. After “fixin” two of them and not seein anything that should of been low, I asked for the overlay (they were already marked on the line); it turned out that he was callin burn thru on all the welds that had low spots on the caps.
100% correct xray can see it but cant tell you how deep it is UT can
We’ll done
need to preheat, if original WPS requires it
Over 1000 xrays in and never had a hitch. More than a few times I've had them re-angle the source because of shadowing though.
Had a grand ol time repairing mistakes by others though. Honestly if I feel like something didn't go right on a pass I stop and grind. What is an extra 10 minutes compared to the time lost if the techs see a piece of slag in the middle of the bevel.
What is shadowing ?
👌👌🤜
Lmfao is that a stick man humping the x ray on your shield, “fuck x ray”
Indonesia 👍
Hello
Can we get a weld gouging video?
I've always heard to 'drag the slag' when welding stick, but it looks like alot of videos show welders pushing uphill on pipe. Wouldn't that increase the risk of inclusions?
If you run 7018 downhill the slag will want to jump ahead of you and it will be worse for slag and porosity
going up you want to push the gravity plays a big factor
@@roadkillfrog5591 you can't drag uphill?
@LTgomez 72 i add a little side to side jiggle so my beads dont crown up as well
@@roadkillfrog5591 Agree with you I dont even weld but been studying a lot on pipe welding down hill pipeliners dont use 7018 the lowhyd is for uphill they run rod ending in 10 6010 7010 8010. And I gotta say Ive been off the weld sites lately but weldtube is awsome I am thouroughly impressed with the talent on here. not to mention some awsome pipeliners that have own channels as well. keep it up!
Estaría mejor que hicieras uno en inglés y otro en español, u pon subtítulos en español
What those defects did the welder repair regarding in the video?
I've never seen anyone put arrows in the direction of the markers and X-raying the weld after grinding is a preference to the company. That's not as common as it should be.
NICE JOB, have u ever done the Same F--k up twice on the same, dig out and repair ?, I have !!!, what a F-ck!!!, anyway. Great Video, Great tutorial. Keep it up, Thanks William Orange, California.
Jaja in the test you are reparing o god ,,,
Hey, please promote more use of respirators. take it from the vets, we need our lungs more than we know it. stay safe
Respirators for when grinding ? Or when welding ?
Why dont you raise your stand to where you can weld without having to hunch over?
Nice video
