3G Combo Welding Demo: TIG Root and Hot Pass with 7018 Fill and Cap

Watch this 17-minute welding demonstration video where Austin teaches Huntsville High School students how to perform a 3G combo weld on a plate. Learn the complete process of using GTAW (TIG welding) for the root and hot pass, then switching to SMAW with 7018 electrodes for the fill and cap passes. The demonstration covers proper plate fit-up, executing a GTAW root pass at appropriate amperage, handling restarts, performing the hot pass at 200 amps, switching polarity for SMAW welding, applying fill passes with 3/32 7018 electrodes, creating cap passes using stringers, and properly dressing the completed weld. Perfect for welding students and professionals looking to improve their combo welding techniques for vertical position work.
