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.

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

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
