WebIf helium is the shielding gas, the arc is hotter. Above all, the heat distribution between the core and the edge of the arc is more even. The use of pure helium for TIG welding is rare and restricted to exceptional cases, but the use of a mixture of argon and helium (I3) with 25, 50 or 75 % helium has gradually increased over the past few years. WebMIG (Metal Inert Gas) welding: This process uses inert gases or gas mixtures as the shielding gas. Argon and helium or Ar / He mixes are inert gases and typically used for the MIG welding of non-ferrous metals such as aluminium. Inert gases do not react with the filler material or weld pool. MAG (Metal Active Gas) welding: This process uses ...
