Description
The tool wear, performance life and optimal parameters for the friction stir welding (FSW) of mild and stainless steels were investigated. Bead-on-plate welds were made in AISI 304L stainless steel (6 mm thickness) and A36 cold-rolled mild steel (6 mm thickness) using FSW with argon gas shielding to prevent oxidation of the weld and tools. The influence of operating parameters and tool temperature on tool life and wear was determined. Ceramic-based PCBN tool materials MS80, Q60, Q70 and Q80 were tested. Tool profile measurements were taken every 1 m of stainless steel and every 3 m of mild steel. The main failure mechanism during the welding of AISI 304L was tool failure by high wear rates and cracking, while for A36, tool wear was the primary failure mode.
