Welders weld ferrous and non-ferrous metals in all positions, on both plate and pipe, using SMAW (Shielded Metal Arc Welding), GTAW (Gas Tungsten Arc Welding), and FCAW (Flux-Cored Arc Welding) processes.

Welders use manual or semi-automatic welding equipment. They use flame-cutting, brazing, and air-arcing equipment. Additionally, they use brakes, shears, and other metal straightening and bending machines. They generally plan work from drawings or by analyzing the job tasks, determine the materials required and welding processes, then use their knowledge to complete the job. Welders use blueprint symbols to determine machining operations. They check product specifications using precision measuring instruments, maintain equipment and replace parts when required. Welders use a logbook to record training, competencies, certifications, endorsements and employment history.

Welders may specialize in certain types of welding, such as custom fabrication, shipbuilding and repair, pressure vessel welding, pipeline construction welding, structural construction welding or machinery and equipment repair welding.

Students who complete the Welder Foundation program will receive Levels 1 and 2 technical training and 300 work-based hours credit toward completing their Welder Apprenticeship. Certified welders will qualify to test for Pressure Welding IT Procedure tests administered by Technical Safety BC (TSBC).
