Abstract

The results of investigation of the formation of a spot welded joint in welding aluminium alloys with a constricted arc with a tungsten electrode and alternating current in argon are presented. The technology of spot plasma welding of aluminium alloys has been developed. The results of metallographic analysis and mechanical tests on welded specimens show high-strength properties in the absence of defects in spot welded joints.
