An attempt is made to reduce the process forces and tool wear during friction stir welding of 409M ferritic stainless steel and to enhance the mechanical properties by induction preheating of base metal with different preheating temperatures at the leading of tool. It is observed that the preheating significantly decreased the longitudinal and axial forces. Tool degradation analysis was carried out to find out the loss of tool profile and material. Mechanical properties especially impact toughness values were increased due to significant reduction in the tool wear.

Tool Damage

Four kinds of the welding tools made of PCBN, W, WC and Al2O3 were applied to FSW of 304 stainless steel, and then the wear and reaction between the tool debris and the steel matrix were examined for each tool material. Severe tool damage was found in W, WC and Al2O3 tools after FSW, while the PCBN tool was hardly worn. Formations of Cr-rich borides, ferrite phases containing the high W contents and Cr-rich carbides were found in the stir zones produced using PCBN, W and WC tools, respectively. It was suggested that formation of those phases could be expected by calculation using the thermochemical database.
