Abstract

In the present study, stationary shoulder technology was used to fabricate 6061-T6 friction stir lap welding (FSLW) joints. Effects of tool rotating speed on joint features and lap shear properties of the lap joints were mainly discussed. Similar to SSFSW, lap joint with smooth surface, without flash, shoulder marks and inner defects can be obtained using the stationary shoulder system. With increasing the rotating speed, effective sheet thickness (EST) firstly increases and then decreases. Effective lap width (ELW) gradually increases. The maximum EST and ELW are attained at 1200 and 1600 rpm, respectively. The maximum lap shear failure load of 17.01 kN is attained using rotating speed of 1400 rpm. The SSFSLW joints fracture in two modes: tensile fracture and shear fracture. All joints present ductile fracture mode.
