  • Identify different types of welds
  • Understand how to set up and tune a welding machine
  • Select the proper electrode wire, contact tip, and shielding gas
  • Explain safety issues involved with steel welding
  • Know how to properly prepare metal surfaces
  • Explain the proper welding gun angles and techniques
  • Identify and correct weld defects

The content in this course pertains to collision repair professionals and offers students the basic knowledge related to steel GMA (MIG) welding theory in an online, self-study delivery setting. Upon completion of the course, students will have an improved understanding of Gas Metal Arc Welding (GMAW) and the proper use of GMA (MIG) welding equipment, as well as the best techniques for making butt joint with backing, open butt, fillet, and plug welds.

Course Content
The first module covers an introduction to GMAW, including the application of electricity in the welding environment. GMA (MIG) welding equipment will also be addressed, such as setting up and tuning a machine. Additionally, students will learn requirements for proper electrode wire, contact tip, and shielding gas selection. Topics relating to performing welds - technique, surface preparation, and heat management will also be covered. Lastly, a student will understand how to identify and correct weld defects.

The remaining modules of the course detail four different types of common collision repair welds - the plug, fillet, open butt, and butt joint with backing welds. Students will learn to identify each weld type, as well as how to visually inspect and destructively test each weld.
