Needed to join two pieces of mild steel today, with minimal bead and as
strong or nearly so as the parent metal.

So I got each one hot, got a thin coating of brazing rod melted onto
each one, then slapped them together and heated the back of the
accessible piece.

Poof! Instant bond. What a joy brazing is.

Is this an accepted procedure? Are there any pitfalls that I should
know of? How likely is it that I've got a joint that's mostly flux?


Yes. It would be called tinning if it were soft solder.
If you have a good fitting joint, and you have enough brazing melted
on to fill the gap, you should have a very sound joint.


I figured that, but wanted to know.

(I just posted again, because I'm having trouble with my news reader, or
with my news service. Gotta check with my ISP -- although I'm afraid
that if I remind them they carry newsgroups they may cancel them entirely!)



Giganews has been real crap lately. I have to log back in very
couple messages.
