When I was working in the gas industry, I developed an appreciation for very good 6010 welds. More of ours were downhill, so a bit easier to get a pretty weld.

I split all the other discussion to a new thread in Firearms. This part of the
forum can be read by visitors. Whereas the other section cannot, just being
overly cautious on open content.

Tim,
6010 electrodes are designed for a DC power source- when you think pipelines -thing that the engine driven power sources were Dc machines.

6011 AC is meant for an ac shop based machine though some brands state they will do both AC and DC.

I am amused at specs that require 6010 or 6011 root run and a 7018 cap.

The root run is placed with a cellulose based flux-(thats up up to 2% volume moisture content ) then run in the cap passes with a LH 7018 electrode.

Does the hydrogen scavenging ability of the 7018 electrode flux negate the moisture and deposited hydrogen left by the cellulose based electrode?

In reality, the answer is that the low carbon steel is not loaded enough for any real hydrogen based cracking problems to occur.

Its really a case of monkey see monkey copy in many instances.

I do admit to liking LH series electrodes as they can scavenge flux from the base electrode and spit it out.If you have ever noticed the LH stick arc crack and snap
,this is exactly what it is doing.

The same stuff ejected is what usually finds it was under your leathers.

All the 6011 that I have bought, that being Hobarts, will run on DC as well as AC. I am not sure if Lincoln 6011 Electrodes will run on DC, however I have a good idea that they will. I thought that I have seen on this forum that someone from Canada said that they do not use 6010 in structural. I thought I have seen that on here but I could be mistaken.

Thanks
Tim

Thanks

Here is what the AWS Electrode classification standard says

Digit Type of Coating Welding Current
0 High cellulose sodium DC+
1 High cellulose potassium AC, DC+ or DC-

0 as in 6010
1 as in 6011

Do you want to hear something strange? A couple of years ago I went to an LWS and asked if they had any 6010 rods and I was told "No because no one around here does any pipe welding"! Something about that just didn't sound right to me.

Thanks
