Abstract
Results of investigation into transverse tension properties of 1.9 mm thick welded joints in aluminium alloy AMg6, made by hybrid laser-arc welding and MIG welding in argon atmosphere by the traditional technology, are presented. Effect of such postweld treatments as removal of weld reinforcement and high-frequency peening of metal surface layers at the weld toe is considered
Keywords: aluminium alloys, thin-walled structures, hybrid laser-arc welding, metal electrode welding, butt joint, mechanical properties, tension, weld reinforcement, high-frequency peening
