I'm currently in school and I'm having a problem with my root. I'm do really good on the fill and cap with 7018 but, the root with 6011, I'm suckin with.

I'm currently run on 85 Amps with a 1/8 gap and landing. Using a 1/8 6011 rod.

I have been reading lately that I could use 3/32 gap and landing. Is that true? And if so, how is it different then 1/8 gap and landing?

Also, while running the root do I keep the rod at the top of the landing and let the rod burn through? Or do I press the rod through the landing out the back?

Also, it 85 too hot?

I'm running on 85 Amps with 1/8 face and Gap using a 1/8 6011.

While I'm welding should I put the rod on the top of the face and let the rod burn through? Or push it through?

Can I drag it or is whip and pause better?

And if I whip and pause do I whip the whole rod width or about half?

What's the right amperage? I'm using 85. Can I start lower?

Also, can I use a 3/32 gap and face with a 1/8 rod?

If so, what's the difference in 1/8 and 3/32?

Thank you

What problems are you having with the root???

ps. welcome to the forum.

I was blowing out the key hole...

I figured out the speed I need and amperage.

Also another problem I had was not preparing my plates right. Landing was a little off, gap was a little off.. Or a high-low problem with the plates.

It's a fine line

Keep a tight arc, when you long arc there will be more heat input which can cause you to keyhole out too big. For open root I like to run about 75 amps so 85 does seem a bit hot too me although sometimes for field welds I will run 85 (but most of the times the gap is not constant due to rough fit up circumstances). I would try running on 75. Don't be afraid to experiment with amperage, for 2 inch pipe coupons I work with people who go as low as 65 and still pass xray.

[Skillets365]

Yep... That's was my problem. The weld arc.... I was long arcing way to much.

Does the gap and landing need to be the same size as the rod (1/8) or can I go smaller and a little tighter?

[DylanWelds]

I would keep the landing about an 1/8 but the gap you can close a bit. I like to use a 3/32 gap myself if possible

[Skillets365]

Thanks man, I'll try the 3/32 gaps this week.


Can I do circular motions with the 6010 on 3G plate? Or Is it only whip and pause and dragging?

[DylanWelds]

You can do that if it works for you. Some people I work with do sort of a back and forth to ensure that they are tying in both plates/pipes together fully. As long as your tied in on both sides with good penetration you should be good to go in my eyes. Are you in welding school currently?

[Skillets365]

Yes I'm in welding school.. I have done a lot better since I have been reading this forum and getting tips on what I need to do. I have passed the 3G plate. On to over head
