Study on the Organisation and Mechanical Properties of the Static Shoulder Friction Stir Welded of AA6003-T6 Aluminium Alloy

Aluminum alloy is a material of particular significance within the domain of light weighting research. The present study investigates the effects of welding parameters on the forming and mechanical properties of static shoulder stir friction welded joints of 3 mm thick 6003 aluminum alloy. It was determined that the optimal quality of welds, characterized by their formation and absence of defects, was achieved through the utilization of static shoulder stir friction welding at speeds ranging from 3.000 to 4.000 rpm, with ω/v maintained within the range of 3 to 4. These results emphasize the importance of the welding parameters on the results.
