VOB 164 - Career Gas Tungsten Arc Welding (TIG)

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 Tungsten Arc (TIG) process. Emphasis will be placed on the student’s ability to prepare material and perform welding of flat, horizontal and vertical fillet welds and flat groove welds in carbon steel, stainless steel and aluminum. Practice is geared towards AWS D17.1 Fusion Welding for Aerospace Application. 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, horizontal and vertical fillet welds, and flat and vertical groove welds.
