I need to mend a small piece of stainless steel, it's essentially a
small length of tube (125mm dia or so) with a flange that needs to be
re-affixed to a then plate. The original welds (not mine!) were
absolute rubbish and have come apart.

I don't have TIG (only MIG and stick) so I think brazing is probably
the best option. I have a gas torch which can get it hot enough, so
what's the best sort of brazing material to use?

The stainless is probably one or two mm thick and the joint needs to
be reasonably strong as it's holding chimney cowl to a chimney.

Silver Solder - Easyflo is you still have some or the non-cadmium equivalent
such as Silverflo 55

Flux - you will need a flux such as Tenacity 5 which will still be active
with prolonged heating.
