College Certificate - Welding Techniques (T166)

Employment opportunities in the welding trade span several industries, including transportation, petrochemical, oil and gas, aerospace, fabrication, manufacturing, pipelines, mining and construction. George Brown College’s Welding Techniques program prepares students with practical, hands-on experience that applies the technical theory and elements of the welding field. Students articulate their technical and essential employability skills through an e-portfolio, based on skill development throughout the program. At the end of this intense, two-semester program, students will have the opportunity to challenge the shielded metal arc weld test, in accordance with CSA W47.1/W59 standards, in a position(s) of their choosing through the Canadian Welders Bureau. (This test will be voluntary and at an extra cost to the student.) This experiential program will provide students with the skills to master five of the most common types of welding processes: Shielded Metal Arc Welding (SMAW): This process uses a consumable electrode covered with flux. It is the primary type of welding used in the maintenance and repair industry. Arc welding is usually used to weld iron and steel, although it can also be used for alloys (aluminum, nickel, etc.). Gas Metal Arc Welding (GMAW): This welding process uses electricity to melt and join pieces of metal together. It is generally regarded as one of the easiest types of welding to learn. It is also called Gas Metal Arc Welding (GMAW). It can be used to weld a variety of metals such as carbon steel, stainless steel, aluminum, magnesium, copper, bronze, etc. Gas Tungsten Arc Welding (GTAW): The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. The tungsten and weld puddle are protected and cooled with inert gas, typically argon or helium. It is most commonly used for welding stainless steel and non-ferrous metals like aluminum, magnesium and copper alloys. Plasma Arc and Oxyfuel Cutting: This process utilizes an electrode and compressed gas, forced at high speeds through a nozzle, usually copper, to cut metal, primarily mild steel, stainless steel and aluminum. Oxyfuel cutting uses fuel gases combined with oxygen to cut metals, usually steel. Fabrication: Metal fabrication is the building of metal structures by cutting, bending, and assembling processes. It is a value-added process that involves the construction of machines and structures from various raw materials.
