Abstract :
The Working Group on Project 63.2 of the Transmission Substations Subcommittee of the IEEE Substations Committee has prepared a guide for welding aluminum in substations. This paper presents a final report on the work, which covers the many unique properties of aluminum with respect to welding. Recommendations are made relative to the choice of welding methods and techniques, and selection of materials. Evaluations are presented on the chemical and physical properties of materials, on welder qualification and evaluation, safety, and preparation of joints.
