RE: [PSUBS-MAILIST] stick welding 101

["Smyth, Alec" <Alec.Smyth@compuware.com>]

Actually what I do these days is TIG the root. But anytime I've seen
pressure vessel welds done purely with stick, at least in my experience
I've always seen it 7018 all the way. There are several folks here,
however, that know far more about it than I do.

As an aside, when I was using a crummy AC buzz box I was getting decent
looking welds with 6013 but found 7018 almost impossible to work with,
and put it down to my own lack of skill. However on a DC welder 7018 was
as easy to use as anything else. If you happen to have been playing with
7018 on an AC machine, you really have to try DC.

Hi Alec,

Not yet, but trying to get things in order.  I've been doing a lot of
web research and have seen almost universal suggestion that the root be
done in 6010 because of the deeper penetration into the metal.  I'm also
signing up for a welding class and one of my choices is a class that
deals specifically with 7018 rods.  Another class option doesn't specify
the rod the work with but appears to cover more areas of knowledge (gas
cutting, brazing, etc).
