Investigation of the weld characteristics of AA6016-T4 friction stitch welds in overlap configuration and the influence of stitch length on static and fatigue strength

Journal of Advanced Joining Processes
High-strength, age-hardenable aluminum alloys in car body construction challenge conventional joining methods — especially in mixed-material body structures, as fusion welding is prone to hot cracking and to hydrogen porosity.
