IV. Student Learning Outcomes

Upon completion of this course, a student will be able to:

Differentiate between weldable and non-weldable substrates used in vehicle construction
Understand how to weld and cut high-strength steel and other steels (plasma, oxy fuel, MIG) and demonstrate an awareness of the heat affect zone
Determine the correct GMAW (MIG) welder type, electrode/wire type, diameter, and gas to be used in a specific welding situation
Identify adjustments to the GMAW (MIG) welder to "tune" for proper electrode stickout, voltage, polarity, flow rate, and wire-feed speed required for the substrate being welded
Identify storage, handling, and installation of high-pressure gas cylinders
Identify and implement proper use of PPE while performing welding operations
Determine work clamp (ground) location
Identify the proper angle of the gun to the joint and direction of gun travel for the type of weld being made in the flat, horizontal, vertical, and overhead positions
Learn measures to protect adjacent panels, glass, vehicle interior, etc from welding and cutting operations
Learn measures to protect computers and other electronic control modules during welding procedures
Describe proper procedures to clean and prepare the metal to be welded, assure good metal fit-up, apply weld-through primer if recommended, clamp or tack as required
Determine the joint type (butt weld with backing, lap, etc ) for weld being made
Determine the type of weld (continuous, stitch weld, plug, etc ) for each specific welding operation
Identify the causes of various welding defects and necessary adjustments
Identify cause of contact tip burn-back and failure of wire to feed and necessary adjustments
Identify different methods of attaching non-structural components squeeze type resistant spot welds (STRSW), riveting, non-structural adhesive, silicon bronze, etc

V. Topical Outline (Course Content)
