Abstract
In friction stir welding (FSW) material flow determines to a great extent the weld feasibility and, ultimately, quality. This work reports on the investigation of the effect of tool geometry on the mixing and material flow during FSW of magnesium AZ31B to magnesium AZ31B. The study involves both FEM simulations and experiments. Nondestructive X-ray imaging is used to pinpoint the location of several steel shots (beads) which were pre-placed within the joint prior to FSW. The experimental results were also augmented with finite element analyses using the commercial engineering FEM software Deform the results of which compare favorably with those of the experiments. Resulting mixing behavior was contrasted for several tools with different configurations and geometries including tool with round shoulder and straight pin and others with concave-shoulder with tapered pin.
