I don't know much about welding stainless, but I know it can be done
with a torch.  It requires a flux, I think.  What sort of filler is to
be used depends on the alloy the parts are made of.  Lots of
stainlesses have problems with welding, because the alloy changes, so
different fillers are required, or the welded joints are less
corrosion resistant.  Sorry I can't be more helpful.

The tin man has a booklet about welding stainless, and sells a flux.
