Transient Thermal Analysis of FSW Tool With Different Material by Using Computational Testing Method

Abstract

Friction stir welding (FSW) is a prevalent solid-state joining method. This procedure entails a revolving instrument that comprises a cylindrical pin and a shoulder. The pin infiltrates the material to produce frictional heat, while the shoulder ensures stability and exerts pressure throughout the welding procedure. For more resilient materials, the creation of economical, lasting equipment that can generate robust welds is crucial for the economic feasibility of FSW. The selection of tool material and its design profoundly influence tool efficacy, weld quality, and total expenditure. In this context, structural steel has exhibited superior thermal properties, with the maximum heat flux measured at 81.26 W/mm2. This signifies the material's efficacy in conducting heat to the welding plates, attaining the requisite temperature for a successful welding operation. Titanium tools exhibit a heat flux of 31.87 W/mm2.
