Ernie or anybody else please feel free to jump in,
very thin stainless steel sheet metal 24 gaugewhich is .8 mm or even thinner say .6 millimeter, need to join weld a 1/2 inch diameter small tube same thicknes 24 gauge in a variety of angles.
I like to TIG it or solder it.
My questions;
is it possible to TIG it without a need for back purging somehow to avoid metal crystolizing on the back side ?
what is the smallest torch reccomended for this ?
soldering such material with out badly discoloring it ? what to use for solder and what to use for flux?
I've tried different kind of solders but it turned in to a " no hold" or a big messy blobs and blue metal.
A dealer let me experiment with a TIG + foot pedal , but needles to say I turned that sheet metal into a screen door looking thing :-( full of holes.
your advice is appriciated.
