Course overview

Gas metal arc welding (GMAW) is the most common industrial welding process used today. It is sometimes referred to by its subcategories of metal inert gas (MIG) or metal active gas (MAG) welding.

The Gas Metal Arc Welding training course introduces the equipment and techniques used when performing GMAW. It discusses the design and function of components used in GMAW. This course covers:

  • Gas metal arc welding principles
  • Wire feeders
  • GMAW electrode wire
  • GMAW guns
  • Shielding gases
  • Starting a GMAW arc
  • Metal transfer modes

Gas Metal Arc Welding is part of the Welding and Cutting for Maintenance training series.
