Oh YES!😃🇺🇸🇺🇸🇺🇸
For the frens only!🐸🐸🐸

A friend I worked with for a couple years showed me a technique when stick welding some thicker materials, where you make a root pass with 6011, grind off the slag and top of the bead, then proceed to lay down the succeeding beads of fill with 7018. The idea is the 6011 provides a more thorough penetration through the backside and provides a better foundation for the 7018 to lay down.

Hasn’t “6010 for a root pass, 7018 for cap” been “best practice” for decades?

I will note that 6011 is preferred for AC (lower voltage) welders and 6010 is DC only. I guess if you have a “buzz box” get some 6011.

6010 will burn through rust, scale, … whatever.

Best results are to keep the arc in the puddle. You can still pull nearly out, but stay in the wet part. 😀

Yeah, maybe it has. Didn’t use 6010. I said 6011.

6011 is a low voltage variant of 6010. A lot of the cheap(er) inverter power source welders can’t run 6010, but if you happen to have a SA 200 in the yard, or a big enuf DieNasty, use the 6010. 😀

The “60” is the tensile strength in 1,000 psi units.

The last two numbers encode two different things. The third digit gives (recommended) welding positions:

1 = any position.
2 = horizontal position and flat position.
3 = flat position only.
4 = overhead, horizontal, vertical down and flat positions.

The third and fourth numbers encode the composition of the flux, and as a direct result, the type of current (AC or DC) and polarity.

Sometimes you get a suffix, such as 7018-A1, which is designed for welding 0.50% molybdenum steel, a low carbon, low alloy steel typically used in applications such as pressure vessels and heat exchangers.

What are we drinking tonight?
I just polished off a bottle of wine and was deciding if I should go to bed or work on finishing off this bottle of Whistlepig…

Was facing the same decision after a bottle of Stags Leap cab. Wife helped me out by putting a fudge brownie sundae in front of me.

I’ve heard of 6010, but can honestly say I’ve never used it. One of the reasons 6011 is so popular in my industry is that it doesn’t require a lot of prep. Very popular for field work.

6010 is the same, only better.
