Main Duties

Welders perform some or all of the following duties:

  • Read and interpret blueprints or welding process specifications
  • Operate manual or semi-automatic welding equipment to fuse metal segments using processes such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW), plasma arc welding (PAW), shielded metal arc welding (SMAW), oxy-acetylene welding (OAW), resistance welding and submerged arc welding (SAW)
  • Operate manual or semi-automatic flame-cutting equipment
  • Operate brazing and soldering equipment
  • Operate metal shaping machines such as brakes, shears and other metal straightening and bending machines
  • Repair worn parts of metal products by welding on extra layers.
