Welders use manual or semi-automatic welding equipment to fuse ferrous and non-ferrous metals in all positions, on both plate and/or pipe, using SMAW, GTAW, and FCAW processes. They use flame-cutting, brazing and soldering equipment, melting and fusing pieces to be joined to form a permanent bond. They also use metal-shaping machines such as brakes, shears and other metal straightening and bending machines.
Welders 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. They may specialize in certain types of welding such as custom fabrication, ship building and repair, pressure vessel welding, pipeline construction welding, structural construction welding or machinery and equipment repair welding.
Certified welders will qualify for Pressure Welding tests in British Columbia, administered by Technical Safety BC.
Welder is a nationally designated trade under the Interprovincial Standards Red Seal Program.
