Observation of Metal Flow Phenomenon of Lap Joints during Friction Stir Welding
Two kinds of aluminum alloys have been used as lap joint in FSW. Experiments are selected to observe metal flow by metallurgical procedures. One is for the effect of probe type and pre-friction time on metal flow at start point. Another is for the effect of probe type on metal flow for stable traveling stage. Thermal analysis also has been carried out.
