Abstract

The work emphasizes weld quality as a measure of weld performance considering tool rotational speed as a variable parameter and investigated the effect of rotational speed on friction stir welded (FSWed) AA2024 and AA6082 alloys. Both alloys (6 mm thick) were fabricated using stir tool of shoulder and pin diameter as 20 mm, 7 mm, respectively. Specimens were welded using different rotational speeds of 1000, 1400, 2000 rpm for a given tool traverse speed of 25 mm/min. Mechanical properties of welded joint were characterized under different rotational speeds. Variation in rotational speed showed strong influence on tensile strength as well as on micro-hardness. HAZ zone was identified as low hardness zone, having hardness value close to base material. Fracture starts near HAZ, and the result is in good agreement with tensile strength value.
