Welding Pipe. 6" Schedule 80

Burning a root pass with a Lincoln 6010 electrode. weld done in the 5G position (pipe horizontal). Used a Miller Dynasty inverter power source on 77 amps. View in video mostly from backside of weld.... duh

im trying to learn on my own i have a 58 lincoln short hood i just practice at home but ive ben having some trouble with the root. the rest i have it down just the root. im sure you went through what ime going through. got any advice?

@zurenoloko be sure you have a landing. i use a 3/32 rod to guage how much to grind off the bevel.just the core wire width. if the root is wider in some spots you will struggle get your prep good and you will weld good . even if you gotta take your pipe to a shop to get it cut and beveled PROPERLY

[AndersonLocksmith]

i traditionally feather out but made an exeption not to shoot sparks all over the place in my vid. Yes you should do it zurenoloko

too hot buddy. thats why u gotta whip it so much. should run nice and smooth with little manipulation. maybe a whip here and there but not like that. keep at it. ull be a welder someday

[AndersonLocksmith]

@budgaugh24 That was awfully hateful Bud i was running my heat at 75 amps maybe i should have adjusted my arc control dial. Are you familiar with those?

[AndersonLocksmith]

would you fire up a 5 inch dewalt with a 200 dollar camera 2 feet away ahah . i know you are supposed to though...

I usually run my root in at 1/16" with a 1/16" land around 77amps. Instead of stepping out and coming back in try just keeping your electrode still with a little bit of a half moon movement and try to pull your electrode instead of pushing it and it will come out really nice and consistent.

@budgaugh24 it's good to learn the whipping motion. When u get out in that field dnt always expect nice tight fit-ups.

Work on that restart in your overhead,and I like to go all the way thru my overhead and get it out of the way.And remember pipe welding can't be just good enough it's gotta be 100% or you won't pass X-ray.

give your head a shake marcellus!!!!

I've never tested in that position. Always in a 45* 6 and 2 inch pipe. Ok root pass might pass

[mpthomasca]

nice job you dont have to chip of slag it will burn out ,onley the 7018 needs a good cleaning.we do the 2 inch pipe on 45 degre angle.6010 3/32 root filerup 7018 3/32.

[cantthinkanameup]

@AndersonLocksmith I typically use a 3/32 gap with a 1/8 land. I like this better because you can go straight from 1/8 6010 @ 85 amps to 3/32 7018 without adjusting your heat. I only do this in position though, as in any other circumstance 85 amps for 7018 isnt hot enough for me.

Love that "keyhole"
