A Welder permanently joins pieces of metal or manufactured parts using metal filler and heat and/or pressure, builds structures, repairs broken or cracked parts according to specifications and carries out special processes, such as welding studs. Specifically, a Welder:

  • lays out, cuts and forms metals to specifications
  • fits sub-assemblies and assemblies together and prepares assemblies for welding
  • uses three major types of welding: arc, gas and resistance
  • uses various welding and cutting processes to join structural steel and cut metal in vessels, piping and other components
  • fabricates parts, tools, machines and equipment
  • joins parts being manufactured, builds and repairs damaged or worn parts
  • controls for quality before, during and after welding

Apprenticeship program

The Welder (456A) apprenticeship program consists of on-the-job and in-school training. The program typically takes three years to complete and consists of:

  • 5,280 hours of on-the-job training/work experience
  • 720 hours of in-school training

  • laying out, cutting and forming metals to specification

In-school training

A Welder apprenticeship includes three levels of theoretical training delivered in a classroom, which includes subjects such as:

  • applied safety procedures
  • reading of blueprints and welding symbols
  • material and process quality
  • welding theory
  • shielded metal arc welding
