Mayf;
I tried that type of "aluminum welding rod" a number of years ago. It's
actually an aluminum solder that's sold under a number of different names. I
think the main constituent of the alloy is zinc. It works OK for doing small
household repairs such as fixing pots & pans (if the surfaces are really
clean) but avoid it for anything structural or subject to vibration. It is
very brittle and it isn't a substitute for heliarc welding on aluminum.
There are some decent aluminum brazing alloys available that are far better
than those zinc- based aluminum solders. If the aluminum is clean and the
correct flux is used, two pieces of aluminum can be brazed together nicely
with an oxy- acetylene torch. The aluminum must be weldable alloys such as
6061, however. High- strength alloys like 2024 or 7075 aren't weldable or
brazeable (is that a word?).

Subject: J.C Whitney Product Question
J.C. and I have a long history and I am always trying his (hers?) products.
In the most recent catalog mailing I see something called the "Aluminum
Welding Rod Kit". This stuff purports to be good enough to repair radiators,
etc and that the 'repair is stronger than surrounding area'. Now I gotta
ask... has anyone actually used this stuff? If so, what was your experience?
Good, bad ugly or what? I know real racers wouldn't use it, but maybe us
wannabie's would..
