Sorry, I didn't mean to call you old. :laughing:

[Arc weld]

I think pretty much every stick electrode has something in the coating/flux that goes into the weld metal. All rods can pick up hydrogen. I think I read 6010 is actually more prone to picking up hydrogen. 7018 and other XX18 are called low hydrogen because they pick up the least amount of hydrogen. For critical work they are kept in an oven to keep the lowest possible hydrogen pick up properties. I doubt anyone on here really needs to worry about hydrogen embrittlement.

A small point, but the flux picks up moisture, the hydrogen disassociates in the arc to introduce hydrogen to the weld.
I'm not strong in chemistry in any way, that's just how the technical papers I've read explain the process.

I also completely agree that for most people, this is a moot point and won't bother anything welded at home.

I understand, Terry. Mine do the same to me.

Payback, though is calling them your "Baby" in public.

I was showing her a pic of GE welder from the 1930' s yesterday. Her response? Quote: I know of an older looking weldor from the early 1950's
