VOB 163 - Career Gas Metal Arc Welding (MIG)

This course is designed to enable the student to learn safety, material and equipment setup, and basic techniques for oxy-fuel, gas metal arc (MIG), gas tungsten arc (TIG), and shielded metal arc (Stick) welding. Students will also explore basic metallurgy, welding codes, inspection, and symbols. Students will then advance their skills in the Gas Metal Arc (MIG) process. Emphasis will be placed on the student’s ability to prepare material and perform welding of fillet and groove welds in carbon steel in all positions. Practice is geared towards Structural Welding Code vertical and overhead tests. Topics to be covered include welding safety, cutting operations, operating oxy-fuel and cutting equipment, basic welding symbols and codes, common alloy metallurgy, material and machine setup, welding inspection methods, fillet welds, and groove welds.
