   No, it was brazed with a zinc wire using a propane torch. No flux
   needed.
   I do have an AC/DC TIG welder, this was just an experiment.

     [DeTomaso] Soldering/brazing aluminum

     A few weeks ago I learned that you can solder/braze aluminum and pot

     metal using zinc solder. I assume you would be able to solder/braze

     magnesium alloys too, which would be interesting as I recently
     bought

     a used camera that turned out to have a cracked front cover and it
     is

     made of a magnesium alloy.

     I ordered some pure zinc wire from Amazon, which arrived yesterday.

     I had already gotten a used, non cracked,  front cover and fixed the

     camera, so I could play with the cracked piece without any risk.

     Tonight I played with it and started by brazing together two pieces
     of

     aluminum, which turned out good. I then tried the front cover, but

     that is very thin and it melted through before I could get the zinc
     to

     flow properly.

     Here is a picture of the brazed two aluminum pieces:

     So this seems like a simple method to fix non critical pieces like
     pot

     metal.

     I?ve seen people play with this and the joint appears stronger than

     the aluminum.
