Sweat Brazing?

You say that Tim Wescott fell down the old rec.crafts.metalworking mine and will die if we don't mount a rescue by Sun, 12 Sep 2010 15:16:24 -0700: 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. -- Politicians should only get paid if the budget is balanced, and there is enough left over to pay them. |
