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 . |
