[TheForge] Stainless steel Welding

[Michael H. Murphy]

I don't know a lot about welding, so I've probably done things I wasn't
supposed to.  At one point, I needed to attach a stainless tube to a black
iron pipe.  This was not structural, so I just grabbed the 6011 I normally
use, and stuck the thing together.  Ain't pretty, but it seems pretty
strong, and it works for what I want.
