Description
A 16-run screening design of experiments (DOE) was conducted to analyse the effects of nine factors during friction stir welding on process forces, temperatures and shoulder depth. The factors were spindle speed, feed rate, plunge depth, pin length, weld cooling, X start distance, weld location, pre-weld cooling and dwell time. Friction stir welding experiments were conducted with an Al alloy 7075-T7351 plate and a tool made from heat-treated H13 tool steel. Spindle time, feed rate and plunge depth were the most significant factors during friction stir welding. The distance between the weld and side of the plate had a significant effect on measured Z force and shoulder depth.
