- 🔥TIG Welding a Carbon Pipe Patch. Embark on a welding odyssey with me as I TIG weld a patch on a carbon pipe, ensuring it meets uncompromising X-Ray and UT standards. 🌐 In this video, I'll not only showcase the precise welding techniques but also delve into the challenges welders face when fixing pipe ruptures. Discover the step-by-step process of preparing the joint, and navigating the complexities of patching large pipes. 💪 Learn how I overcome obstacles, from intricate joint preparation to the finesse required for welding on a grand scale.
🚧 High-velocity steam flow, can cause erosion and abrasion of the pipe material. This can result in thinning of the pipe wall, making it more susceptible to rupture. 🛠️ Join me as I explore the root causes of these ruptures and unveil the strategies employed to restore the pipe's strength and reliability. Gain insights into the welder's expertise in mitigating the impact of water hammering, ensuring a robust weld that stands the test of time.
None of these videos are recorded in a fancy shop surrounded by sponsorship banners!
My videos are recorded at working sites in various locations and welding positions.
90% of my welding projects in videos are x-rayed, and if you like to see hands-on projects, welcome!

That wrap trick is slick
Yeah imma be taking that
I wonder why they did not just replace that section of pipe entirely. Patch looks great anyway. Fire content keep it up
I sure do miss tig welding!!! Watching you makes me just want to get back into tigging!! I work for pipeline company and all we do is stick per API 1104. You are a master and great skilled craftsman!!!
Stick can definitely get repetitive I also miss toy greatly
I literally weld all day at work, and then even after work on side jobs, and then at night I watch your videos...really enjoy them
That is awesome! 🍻
And when going to sleep, carry on welding in dreams.
Very cool! I've never seen a patch on a pipe before
I love your videos
Excellent camera work. Thank you for the great video and tutorial.
Excellent work man… your Fitter’s Grinding skill is remarkable. Tough to find these days
I was hoping they showed him bevel that. Looked like a torch did it
I appreciate that! It sure is!
That is unreal what the steam did to that pipe! You and your partner are quality craftsman. Beautiful job on that. 👍🏻
I am a welder/fitter for the steam side of my plant. This is awesome info! Thx!
I don't comment much but the in the field welding is so nice to see . I appreciate your videos , they are very informative . Thank you !!!!!! and keep the videos coming .
I appreciate that!
Phenomenal work
Thank you so much for always making good videos. It was lots of help to me
If you have any chance could you make 309 stick pipe welding? Thanks
Noted!
God bless you and keep up the great work!!
Thank you!
This is great content man!
Great, this patching video is not something that often can be seen on RUclips, and it goes in my favorites. 🙏 thanks.
Thanks for the great contribution of both the videos and your explanation.
Fascinating m8 thanks for sharing quick question on the top left, and maybe bottom right corners which would be your awkward corners as you are a right hander, did you still use your right hand or did you freehand with your left? Cheers mate
Good question, I did all with my right hand, top left corner was little tricky but not big deal.
@@X3MTIG you must have been folded in half like a sandwich lol 😆
Very good and precise. Wish you could show the puddle 😂 but your tips during the welding is enough and it is understandable. Thank you ❤
Good job nice and clean how long did that take
10 hours shift
That was a good job thanks for responding back
Awesome stuff. Do you ever see any jacketed pipe? Would be a big help to see your method on that procedure
I got one older video welding jacket pipe.
@@X3MTIGI'll watch it for sure. Your vids have been a huge help. I've been watching them and then burn some coupons in my shop over and over. You helped me go from just structural to hastelloy and economiser tubes. Just got to the end of the season working at CEDA where Travis field @fieldres was before. Might be a long shot but I'm looking for work. Do you know anyone looking for a welder?
@@X3MTIGwhere can I find that video of the jacketed pipe video you did
This is usually done on DA/expansion tank, boiler shells etc- I’m surprised they didn’t just cut the section out completely. With that much internal damage- I’ll also be surprised that they didn’t utilize a thicker section of steel, hard coat the inside or add a double section externally.
I second that. It might have to do with union overlap, meaning that if the plant has contracted UA and Boilermaker and Millwright unions that the contract would be breached if it was a boilermaker making the fit up on a branch cut out. Rather they can kinda sneak out of calling a certain union if it’s a patch, there by saving money and time.
Emergency outage, no time for replacement pipe section, also it’s connected with branches that are Cr. so lots of money and different contractors would be involved to get this job done properly. Next outage is scheduled for next year, and they will be replacing everything!
It looks pretty good. I just don’t get why you piled up those stop/starts all in the same place. Not considered a good practice. May even be a code issue… not sure.
It’s not a code issue, but it’s not good practice, you right.
Nice video thanks a million
How long does a weld like this take ?
Hello chap. Can do me a favour and make a proper video about walking the cap? I’m trying to learn walking the cap, but honestly is a bit hard to practice. If u just can show some techniques and how to learn in a proper way to it simple and easy to catch up. Thanks, as aleays good video.
That is not carbon steel, it is CrMo in all likeliness, or it should be in steam service. I am surprised it wasn't a cut out rather than putting in a patch! I am guessing an Engineer has approved this technique for repair, your seamless pipe is now welded pipe..? Could have put in a thicker patch to allow for future erosion... PWHT / Hydro to follow...
Having said that nice to see a video of what you are doing.
Thanks for your comment, pipe is carbon steel, and branches that are connected are Cr. One of the reasons why engineers didn’t cut out the section and instead approve the patch is to avoid all those different materials being welded, and pwht involved etc. Closure weld procedure usually eliminates need for hydro testing. This was emergency outage and time is crucial, also this should be good for a year until next planned outage is scheduled.
Closure weld never eliminates the need for a hydro per ASME, unless a local law provides for that, which is unusual.
I noticed you were using a CrMo filler to fill what you say is a carbon steel weld, it seems strange to do that, are you sure this is not CrMo material.
In any case I am pleased you have posted this, this window technique can also be used to weld out pipe when only 180 degrees around a pipe is accessible, such as inside a boiler tube rack. Thanks for posting it.

@@paulmeersa7162 According to ASME B31.3, the closure weld procedure can eliminate the need for hydrostatic testing in certain cases. The closure weld procedure involves welding a closure weld at the end of a pipe or system to seal it off.
If the closure weld procedure is performed in accordance with the requirements specified in ASME B31.3, and if it is demonstrated that the closure weld provides a leak-tight seal, then hydrostatic testing may not be required. However, it is important to note that this exemption from hydrostatic testing is subject to certain conditions and limitations.
The decision to eliminate hydrostatic testing based on the closure weld procedure should be made in consultation with the applicable codes and standards, engineering judgment, and any regulatory requirements that may be applicable.
Yes, you can weld carbon steel pipe using a TIG welding process and the ER80S-D2 filler rod. ER80S-D2 is a low-alloy steel filler metal that is commonly used for welding carbon steels. It provides good strength and toughness properties and is suitable for welding carbon steels in various applications.
If this is steam piping it is likely that the code is B31.1?@@X3MTIG
