  1. Methods of Aluminum Welding Cory Whidden Material Science Larry Peel 11 – 26 - 04

  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

  4. 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

  5. The TIG-welding process.
