CRT 1032 - Welding, Cutting, & Joining

This course is designed to train students in Metal Welding and Cutti ng such as preparation, different types & techniques of MIG welding, and panel alignment required to be proficient upon entering the workforce.

Student Learning Outcomes:
A.  Metal Welding, Cutting, and Joining

·       Identify the considerations for cutting, removing, and welding various types of steel, aluminum, and other metals. HP-G

·       Determine the correct GMAW welder type, electrode/wire type, diameter, and gas to be used in a specific welding situation. HP-I

·       Set up, attach work clamp (ground), and adjust the GMAW welder to “tune” for proper electrode stickout, voltage, polarity, flow rate, and wire -feed speed required for the substrate being welded. HP-I

·       Store, handle, and install high-pressure gas cylinders; test for leaks. HP-I

·       Determine the proper angle for the gun to the joint and direction of gun travel for the type of weld being made. HP-I

·       Protect adjacent panels, glass, vehicle interior, etc. to prevent damage from welding and cutting operations. HP-G

·       Identify Hazards, foam coatings, and flammable materials prior to welding/cutting procedures. HP-G

·       Protect computers and other electronics/wires prior to welding procedures. HP-G

·       Clean and prepare the metal to be welded, assure good metal fit-up, apply weld-through primer if necessary, an clamp or tack as required. HP-I

·       Determine the joint type (butt weld with backing, lap, etc.) for weld being make. HP-I

·       Determine the type of weld (continuous, stitch weld, plug, etc.) for each specific welding operation. HP-I

·       Perform the following welds: plug, butt weld with and without backing, and fillet etc., in the flat, horizontal, vertical, and overhead positions. HP-I

·       Perform visual evaluation and destructive test on each weld type. HP-I

·       Identify the causes of various welding defects; make necessary adjustments. HP-I

·       Identify cause of contact tip burn-back and failure of wire to feed; make necessary adjustments. HP-G

·       Identify cutti ng process for different substrates and locations; perform cutti ng operation. HP-I

·       Identify different methods of attaching structural components (squeeze type resistance spot welding (STRSW), structural adhesive, MIG bronze, weld bonding, etc.). HP-G

·       Perform rivet bonding procedures. HP-I

·       Dress/grind weld as needed. HP-I
