Steel GMA (MIG) Welding (WCS03)

Course Overview

Major collision damage requires a greater level of expertise to repair. Welding is one of the most critical skills necessary for completing such repairs safely. Poor welds can lead to part failure and compromised safety for vehicle passengers.

Gas Metal Arc (GMA) welding on steel has many advantages and is a common practice in today’s collision repair facilities. From machine setup to mastering refined techniques, it is critical that technicians have a thorough understanding of GMA (MIG) welding to perform complete, safe and quality repairs.

After completing this course, you will have proven your ability to:

  • Properly set up, tune, and maintain a welding machine
  • Make common GMA (MIG) welds on multiple thicknesses of steel in vertical and overhead positions
  • Perform proper welding techniques

A single training event can accommodate multiple technicians.

Course Content

Welding Capability & Readiness Assessment
Before instruction starts, the instructor will conduct the Welding Capability & Readiness Assessment to determine whether shop infrastructure and equipment conditions are adequate for technicians to properly perform hands-on practice and certification testing.
Students will be provided with instruction on welding theory, infrastructure, equipment, processes, techniques and best practices. Students will be coached on:
  • Machine setup and maintenance of GMA (MIG) welding equipment in the facility
  • How to identify and correct defective welds
  • How welds will be visually and destructively tested for certification
Hands-on Practice
Following the instructor-led training, students will apply their knowledge through practice with combinations of GMA (MIG) plug, fillet, butt joint with backing, and open butt joint welds. The time spent on supervised practice will be based on the student’s skill level and visual and destructive testing results.

Students will work with two different thicknesses of automotive-grade, zinc-coated steel - 16 gauge (1.4-1.6 mm) and 22 gauge (0.68-0.81 mm).
Skills Verification Test
The final phase of the training consists of the student taking the hands-on test, in which the student demonstrates the ability to perform the specified 10 welds. All 10 welds must pass I-CAR standards for the student to receive the certification.

Students will be given multiple attempts to perform each weld if necessary. Those who are unable to properly complete all of the welds during the event may retake the training and test and pass it on another date to receive the certification.

Training for Your Role

Successful completion of the Steel GMA (MIG) Welding satisfies the Knowledge Area training requirement in the Professional Development Program, but it does not award credit hours.

All earned I-CAR Welding Training & Certification designations are valid for five years from the passing date.
