In this welding class, you’ll learn two new, but related welding processes: GMAW, also called MIG, and FCAW, or Flux-core. In both processes, a thin metal wire that serves as the electrode is fed into the weld pool from a welding machine, where it serves as the filler metal. The main difference is that GMAW uses a gas to shield the work from environmental contaminants, and, with FCAW, the metal wire contains a powered flux that protects the weld as it burns off.

  • Set up and operate GMAW and FCAW machines and equipment.
  • Prep pipe for GMAW and FCAW applications.
  • Demonstrate the ability to interpret the procedures, codes, diagrams, symbols, and fitting markings for pipe welding projects.
  • Show advanced reading comprehension for blueprints and layouts.
  • Execute 2G, 3G, and 4G Weld Root Fill and Cap.
  • Use beveling methods to prepare pipe.
  • Weld in the overhead position.
