Abstract

A computer model of the temperature field during friction stir welding (FSW) with a superhard materials tool of heat-resistant alloys has been developed. The model was implemented on the basis of the finite element method. The temperature field in the tool and welded parts was calculated. The results of the calculations are in good agreement with the results of experiments during FSW of AISI 304 steel plates. It is shown that, based on the results of computer experiments, it is possible to determine the parameters of the FSW process, which ensure the heat resistance of the kyborite tool during FSW of plates made of this steel.
