Thesis : Effect of Induction Assisted Friction Stir Welding on AISI 410 Stainless Steel
Supervisor : Prof. Dr. S Gopi
Institution : Government College of Technology (Affiliated with Anna University, Chennai), Coimbatore, Tamilnadu, India.
Abstract : The main limitations of friction stir welding are the difficulty of welding hard metals and their alloys and the damage that happens to the tool pin and shoulder. These limitations can be overcome by using an additional induction in situ heating source. Induction heating does not require direct contact with the metals. Induction-assisted friction stir welding is the best method for welding ferrous and other magnetic materials. This welded joint shows higher strength compared to conventional welding methods. By adopting this method, the tool damage rate is also reduced. The tests conducted for the weld specimen are the tensile test, microhardness, corrosion tests, and macro and microstructure analysis. The specimen provides good tensile strength and hardness. The corrosion results show that the in situ heating enhances the corrosion resistance property of the AISI 410 stainless steel. The microstructure evaluation shows no foreign particle formation inside the welded regions, and fine homogeneous grains were found in the welded zone.
