How do you prevent undercut on a 6g pipe welding with 7018. Im having a super hard time with on my last cover pass on the top side of the weld. Especially from like 3 to 9 oclock

Dude, by the time you got past the different electrode manipulations, I forgot this video was about undercut. This was just a really, really good informational video for new welders. Brilliantly done! ✌️👽

Thank you, I’ve been trying to combat undercut in my welds.. this seems to be the ultimate guide

[grumpyone]

Much appreciated. Always worth listening to.🇬🇧

[atomichydrogenweld]

Outstanding, Beau, you are rocking up the great videos....we really appreciate I went to GTCC of 2001

[toolbox-gua]

Great video. Great lesson. Very clear teacher. Thank you.

[victoryfirst]

Thanks for some real great tips on undercut control. Good day fella too.

[ballista]

I’m so glad you made this video before I watched this my vertical weaves looked horrible but yesterday I made mine look like yours

[jwdickinson]

very nice presentation, son! very informative!

[paulenespika]

A very important issue when welding and you addressed it well. I don't want to be Debbie downer, but when it comes to showing the actual arc in motion, Bob Moffitt had the best videos. They focused in on the actual puddle without a lot of flash and flare.

For your age you understand the process. Good job 👍

[mr.ranyhomemade]

Very nice to share your experiences
Thanks 😊

My teacher told me about this yesterday I didn’t fuck up that much because he still got super happy with my weld me being me i like to do things in a perfect way which I know no one’s perfect but thanks for this vid I’ll apply your knowledge with his 🔥💯

Where I work, we weld a lot of 1"- 4" plate and use spray transfer (typically 28.5-29.5V 300-325A with 98/2 gas and .045 wire) I'm getting undercut, but I don't want to dial my heat down too much. Am I going to have to dial down or is there a technique I could try to prevent this? Any help would be greatly appreciated! Also if you are curious about the metal thickness, it is because we do testing on high pressure steam systems 2000+ psig with piping and valves up to 28" sch 160 GR-C. No I don't weld the pipe, we have real nuclear certified welders for that. I just build the stands and fixtures. I would like to get Nuke certs one day though but right now my skills are not up to par for that.

What advice can you give with spray arc? Multipass tee joints. You can't do manipulations. I think in sine situations gun angles go out the door its really about watching the puddle because gun angle will have to be adjusted. I think overheating can also cause a lot of the undercut. The last bead on top is always the hardest weld because its always the riskiest pass if the conditions aren't correct.

Bend testing on a 6G tig root and hot, 7018 fill and cap. I always get undercut on the bottom cap pass

[byronfuentes]

Great job on your video. Was hoping y’all could discuss welding in the downward direction as a means of repairing undercut. Does it work? And why?

[MRJ]

Need an answer asap I just bought “Tweco electrode holder 500 amp”, and this thing is kinda more huge than I expected. I stick weld at delmar college and my other electrode holder is 250 amp but bought a new one because jt sucks at holding rods. Anyways I just need your word if it’s meant for different amperage’s and not low ones like 200-300 amp. Because it was atleast $80 and feel like I kind of wasted money. It looks like it would be perfect for 1/8th rods and even bigger but if you can tell me that it can be used just like my 200amp electrode holder as well I’ll greatly appreciate it.

Does it make any difference whether you are pushing the weld puddle instead of trailing it?
I push most of my welds to pre-heat the parent metal.

Speaking of undercut without ever showing any... thanks... !
