Experimental and Numerical Studies of the Effects of Process Parameters in the Continuous Friction Welding Process
All of the experiments performed on friction welding combinations of 304SS and mild steel are modeled using the ABAQUS code and the Johnson-cook equation is used to define coupled thermo-mechanical properties of materials. The variations of temperature, von-Mises stress, plastic strain, and strain rate during continuous welding are systematically investigated and analyzed. The calculated results of temperature distribution are in good agreement with the infrared detected ones. The numerically calculated results for the shape of the welded joint also show an excellent fit with experimental observations. The von-Misses stress and equivalent strain distributions are more influenced by the initial pressure than the final pressure. The metallographical examinations, hardness and tensile tests of the samples are carried out. In all the tension tests carried out the samples were broken from their base metals and not the welds.
