2. Aluminum Welding Techniques
MIG Welding (Metal Inert Gas)- supplies power to wire fed through the center of gas cone, heat and filler are the same.
TIG Welding (Tungsten Inert Gas) or Heliarc – seperates the heat source from the filler material.

3. MIG Welding Shield gas is 100% Argon
Faster than regular steel MIG welding, due to the higher thermal conductivity
Material must be very clean for effective weld
Good for long runs and heavy material

5. TIG Welding Shield Gas mostly Argon some helium
Electrode usually tungsten
Similar Brazing or soldering
Cleans surface while welding, less prep than MIG
Slower than MIG
Good for thin metal, seals better than MIG, and usually more attractive depending on the welder
