Position Summary:

The Aluminum Welder – Field is responsible for performing specialized aluminum welding activities associated with the installation and construction of isolated phase bus duct systems at a utility substation. This position requires extensive experience with pulsed Metal Inert Gas (MIG) welding using push-pull welding guns and 1/16-inch aluminum wire. The Aluminum Welder will perform groove and fillet welds on aluminum enclosures, conductors, pipe, and plate in various welding positions and outdoor field conditions. The successful candidate must demonstrate proficiency in aluminum weld preparation, fit-up, oxide removal, interpass temperature control, and adherence to established Welding Procedure Specifications (WPS) and quality-control requirements. This position requires successful completion of an AWS D1.2 aluminum pipe qualification test using pulsed MIG welding in the 6G position with an open root and bend testing before mobilization.
