Welding Techniques

This one-year program covers all the theoretical and practical learning outcomes for Level 1 of both the Welder (456A) and Metal Fabricator – Fitter (437A) apprenticeship programs in Ontario. As a student in this program, you will have the opportunity to develop welding skills in a state-of-the-art facility, using modern equipment with the common arc welding processes such as Shielded Metal Arc Welding (SMAW or ‘stick’), Gas Metal Arc Welding (GMAW or ‘MIG’), Flux Cored Arc Welding (FCAW), and Gas Tungsten Arc Welding (GTAW or ‘TIG’).

What You’ll Learn

• Demonstrate the set-up and safe operation of welding and fabricating processes and equipment including a working knowledge of Health and Safety legislation, lock-out procedures, hazard control, personal protective equipment, and WHMIS related information.
• Demonstrate the set-up, application, and troubleshooting of modern industrial welding and related processes including Shielded metal Arc (SMAW), Gas Metal Arc (GMAW), Flux Cored Arc (FCAW), and Gas Tungsten Arc (GTAW), Oxy-Fuel Cutting (OFC) and Plasma Arc Cutting (PAC).
• Describe the theory of operation, applications, materials selection and trouble-shooting of the standard welding and fabrication process and equipment.
• Select, plan, and demonstrate metal fabrication operations including measuring, layout, cutting, forming and fitting for weldment manufacturing using industrial metal fabrication machinery including plate rolls, shears, iron-worker, and press brakes.
• Prepare welding documentation and develop a familiarity with the common welding codes and standards in the welding industry (i.e. ASME and CSA).
• Explain the application of standard inspection and testing methods used to assess the quality of welds and welded fabrications.
• Identify common metals, alloys, and classification systems and select the appropriate welding and fabricating techniques and consumables for adapting to the characteristics of the different types.
• Perform mathematical calculations related to the applications of welding and fabrication technology, layout, and measurement.
• Interpret engineering drawings, welding symbols, bills of material and create piece-part and assembly drawings using CAD software.
