Tensile strength Characteristics on Dissimilar Metal Friction Welding of Ti-6Al-4V & SS304L

Abstract

In this research, the method of friction welding joints in Titanium and Stainless Steel with aluminium interlayer coating is created. The friction welding process is a solid-state joining process of dissimilar or similar materials. This friction welding process needs high rotational speed and high forging pressure. Titanium and stainless steel materials melting temperatures are around 1600OC. Welding process which needed high-pressure, temperature and good velocity regions. Titanium and stainless steels are coated 300OC ranges to applied aluminium spray coating method with constant pressure. The source of the aluminium coating is strong titanium and stainless steel adhesive strength. In this experimental project, four different trials of titanium and stainless steel joints have been performed at different speeds and constant forging pressures. Trial 4 connections of titanium and stainless steel made of 2100OC temperature and forging pressure of 60 MPa, friction time of 5 sec and friction pressure of 70 MPa. Friction welding experiments were completed with the help of friction time, forging pressure, rotational speed and friction pressure. Tensile load stress results are calculated by the UTM machine and evaluated the results of design experts with ANOVA table and RSM.
