Keywords:
Austenitic stainless steel, Friction welding, welding parameters, ANOVA, optimization and tensile strengthAbstract
Austenitic stainless steel (AISI 316) plays a wide range of applications in the area such as food processing, chemicals, cryogenics and heat exchangers. In friction welding process the joints are formed in the solid state by utilizing the heat generated by friction. The objectives of this experimental investigation on friction welded joints of Austenitic stainless steel rods and predict optimum parameters of friction welded joints. The welded joints are produced by varying Friction pressure (Fp), Forge pressure (Up) and forging time (Fgt) considering speed at constant rate. Parameters optimization of mechanical properties such as Hardness values and ultimate strength are analyzed by S/N ratio and analyzed by ANOVA techniques. The results of the friction welding parameters are increasing the Hardness values and decrease the ultimate strength by increasing friction time.
