Advanced GMAW (MIG/MAG) Welding

Catalog description

This course introduces students to advanced concepts relating to the use of the Gas Metal Arc Welding (GMAW) (MIG/MAG) process to make high quality, cost-efficient fillet and groove welds in the vertical and overhead positions in steel, aluminum, and stainless steel. It involves the use of advanced manipulative techniques, and utilizing variations of the process such as short-circuiting and spray transfer, pulsed-arc, and modified current wave-forms generated by advanced inverter types of welding power sources. Safety is emphasized and the additional concerns associated with vertical and overhead welding are explained. Project Based Learning (PBL) is utilized to familiarize students with being part of a team that takes an idea for a product, designs it, and makes it a reality. At the conclusion of this course, students take either a 3G or 4G pass/fail welder qualification test using the GMAW process. An Industry Recognized Certification of Qualification will be awarded to students passing the test. The student must furnish: welding helmet (shade #10 or above); safety glasses; work gloves; long pants; welding jacket; leather work boots, preferably steel toe; 8” crescent wrench; soapstone and holder; tape measure; combination square; chipping hammer; wire brush; tool bag; center punch; and 12 oz. ball peen hammer. 4 1/2” grinder is optional.
