       Atecelyne welding aluminum and magnesium

       This is the way it was done in the old days before mig and tig,
       but you can weld both quite successfully with some practice.
       To weld aluminum you use a small diameter flux-coated aluminum
       arc rod,and weld just like brazing,bring the metal to melting
       point and let the rod flow in.
       Same for magnesium,except you buy bare magnesium rods from a
       welding shop and a jar of Flux,warm the welding rod first,then
       dip it in the flux powder,then melt it in,continuously dipping
       the rod in the flux.
       It is hard to tell when these metals are near melting point,I
       was taught to gently prod the metal with your rod as you're
       heating it,when it is starting to get soft add your rod,once
       it;s flowing it goes great.

       I'm not so sure that method is an actual weld .Now first
       remember I am an actual at one time state of Ohio certified
       welder although I made my living as an industrial electrician
       .Having said that I've had number 6 Gas welding tips with gas on
       aluminum and you can't get it hot enough to puddle because it
       sags first .With a gas rod you have no gas shield like heli arc
       which keeps the oxygen off of the molten metal which doesn't
       change color like steel when it's molten . I'm not saying it
       can't be done but I've never seen it.If so it would have"sugar "
       not a good weld .

       Even with Tig welding it is not easy to see the puddle when
       welding Mag or Aluminum.    It takes a trained and eye and
       practice.
       Al does bring up a good point about the shielding gas that you
       get from Mig or Tig.

       I've seen the vid clips on those supposed "welding rods " .I
       have no idea what they are made of but the base metal is not
       melted ,it's more like a braze or hard solder joint .With brass
       or lead you are heating up the base metal and using it to cause
       the filler flow .The molecules of the base metal has expanded
       and the filler thusly flows into it .Which is not saying a joint
       made like this is not strong it's just not as strong as the base
       metal .
