Effect of Probe Thread on Friction Spot Joint Strength of AZ31 Mg Alloy
Lap joint of AZ31 Mg alloy extruded sheet can be successfully made by friction spot joining (FSJ) process. Joint strength was strongly affected by the probe thread, which increased the plastically deformed zone around a rotating probe and increased the tensile shear strength of the joint in comparison with the joint made by a thread-less probe.
