In the present study, friction stir lap welding (FSLW) assisted by external stationary shoulder was firstly used to weld magnesium to aluminum alloys. Effects of the assisted stationary shoulder on joint surface appearances, cross-sections, microstructure and mechanical properties were mainly studie...
