Steel GMA (MIG) Welding

The Steel GMA (MIG) Welding course includes the use of different thicknesses of material to help students refine their welding techniques. The new materials being used for welding certification in the I-CAR® class are representative of the thicknesses of steels being used on today’s high-tech vehicles.

Topics Covered

  • How to set up, tune and maintain a welding machine
  • Make common GMA (MIG) welds on multiple thicknesses and combinations of thicknesses of steel
  • Perform proper welding techniques – including GMA (MIG) plug, fillet, open butt and butt joint with backing welds, in both vertical and overhead positions

Students will have several opportunities to practice each weld during the training while supervised and coached by an I-CAR Instructor. Because of this high level of Instructor support and interaction, the test pass rate is high. If the student is unable to perform welds that meet I-CAR standards, they must retake the training and pass the certification test at a later date.

All participants finish the course by taking the Steel GMA (MIG) Welding Certification Test to confirm their ability to perform all ten welds as specified. All ten welds must pass both visual inspection and destructive tests.


A current Steel GMA (MIG) Welding Certification is a prerequisite for the 
Steel Sectioning course. Successful completion of the Steel 
Sectioning course will also renew a technician's Steel GMA 
(MIG) Welding Certification for five years from the date of completion of 
the Steel Sectioning Certification.
