Ideally a butt weld should be done using
either TIG (HeliArc) or with a mini gas
torch. Using TIG (my personal preference)
or gas, will give a softer more workable
weld that can be ground perfectly flat
on both sides of the seam and be hammer &
dollied, metalfinished without a worry of
A MIG creates a strong, yet brittle weld
that is not ideal for butt welds and grinding
down flat. I'm not saying it can't be done...
it's just much more susceptible to cracking
and failure, especially if you do any
significant amount of hammer & dollywork.
This also depends on the particular
application... and if you grind down BOTH
sides of the weld.
