GMAW 3-Day Module - MIG Welding

The GMAW Module will expose students to a basic understanding of the MIG welding process.  Students will also learn an understanding of electricity, weld defects, and metallurgy and how they affect the weld.  Students will gain a basic understanding of the language spoken in the welding industry through codes and symbols.

Students will leave the GMAW Module course with more than foundational information and skill, but also a firm grasp of the industry’s needs and nuances. A student leaving the course will have a good foundation in any potential MIG welding career.  However, while this class is not part of a program, students are encouraged to build a more solid foundation in the welding industry with other Process Modules.

The GMAW Module are 3 days long (Tuesday, Wednesday, Thursday), for a total of nearly 22 hours of training.

Students must be at least 18 years old to enroll in this class.
