Temperature Distribution during Friction Stir Spot Welding of Magnesium Alloy AM60B

摘要

This study investigated the effects of welding parameters on temperature distribution of magnesium alloy AM60B during Friction Stir Spot Welding (FSSW). The welding parameters included tool rotational velocity, plunge depth, and holding time. These parameters were selected from previous test results. The temperature distributions were measured with type-K thermocouples during FSSW with various welding parameter combinations. The measurement locations were placed along the centerline in longitudinal direction of the coupons. The temperature distributions during FSSW were also calculated with finite element analysis (FEA) for each combination of the welding parameters. The experimental results were compared with those obtained from FEA.
