passes. The weldment edges should be ground to
form a V, U or J shaped groove to create a recess
where the welds can be welded one on top of anoth-
er. For welding with .035" wire and under, create a
bead no thicker than 3/16" in a single pass, no more
than 1/8" with .030" wire, and with .025"wire and
smaller no more than 3/32 for best results. This will
help maintain proper fluidity of the weld and pre-
vent gas from being trapped in the weld and give
time for any minor contaminates to float out of the
weld. It will also help to maintain reasonable for-
ward travel speeds. Too slow of travel speeds will
create excess build up and can tend to create cold
lap at the weld toes resulting in poor tie in. One
issue created with a weaving technique even if the
metal deposited is the correct thickness s that it can
slow the forward progress down. If weaving is too
wide, one side of the puddle will cool and oxidize
before the torch is brought back across to that side.
This is a point where porosity and inclusions can be
introduced.
