Gas Metal Arc Welding (GMAW), commonly referred to as MIG (Metal Inert Gas) welding, is a versatile welding process used in many industrial applications. Here’s a basic course outline for a GMAW welding class
For more information about GMAW please click here.
Each class is limited to 10 students to ensure every participant receives essential hands-on guidance. 20% of our courses are theory-based and the remaining 80% is hands-on practical experience.
After completing each course, students will have the opportunity to participate in CWB testing and receive their tickets. CWB is the “Canadian Welding Bureau”, now also known as CWB Certification. The Canadian Welding Bureau is recognized as one of the biggest and most innovative welding organizations in the world. They administer welding standards, embedded within the national building code, in Canada. It is mandatory for all companies to be CWB certified within the Structural and erecting industry, however, many non-structural companies voluntarily choose to be certified because of the CWB’s credentials being recognized nationally.
Course Description:
Organizing a GMAW (Gas Metal Arc Welding) practical workshop is crucial to imparting hands-on experience and ensuring participants have the necessary skills for real-world applications. Here’s an outline to help you set up a practical GMAW workshop:
1. Workshop Introduction:
- Overview of the day’s schedule
- Safety briefing and importance of PPE (Personal Protective Equipment)
2. Equipment Familiarization:
- Introduction to the GMAW machine, settings, and controls
- Overview of wire feeders, gun, and torch components
- Understanding shielding gases, their types, and selection criteria
- Setting up the workbench and ground clamp
3. Hands-on Machine Setup:
- Guided session where participants set up the machine
- Selecting and loading the correct wire spool
- Setting the wire feed speed
4. Striking the Arc:
- Demonstrating proper techniques to strike and maintain a stable arc
- Participants practice striking the arc on scrap metal
5. Laying Basic Weld Beads:
- Demonstrating how to lay a straight bead on a flat plate
- Discussing the importance of travel speed, torch angle, and stick-out
- Participants practice laying beads and receive feedback
6. Troubleshooting Common Issues:
- Identifying and rectifying common problems such as:
- Porosity
- Spatter
- Incomplete fusion
- Arc instability
- Guided session on troubleshooting machine-related issues
Notes:
- Participants will need to bring their own PPE (Personal Protective Equipment).
- Welding Machines, consumables, and test materials will be provided by the academy.
Gas Metal Arc Welding (GMAW) Introduction
- Duration: 55 hours (2 weeks)
- Classes run from Monday to Friday, 9am-2:30pm
The learning outcome for the theory portion of the GMAW intro course includes safety, equipment, modes of transfer (short circuit, globular, & spray), and visual defects.
The practical portion of the course will include beads on a plate, stop & starts, padding, weaves, fillet welds (¼”, 3/8”, ½”), groove welds (T & S classification), basic fitting, 1F, 2F, 1G.
*All above courses are NON-Vocational and are not under the PCC Act 2005.
