【 摘 要 】

Due to increase in demand of joining dissimilar material combinations in applications such as cryogenic fluids, power generation industries and reactor cooling systems, the solid state welding is most suitable in the current scenario. In this study, the experiment is undergone to evaluate the impact strength on the friction welded joint of copper and AISI 430 ferritic stainless steel material in the weld interface. The experiment is conducted by varying the input parameters such as friction pressure, upset pressure, burn-off length and rotational speed using Taguchi's L9 orthogonal array. The welded joints were examined under scanning electron microscopy (SEM) and type of failure mode is discussed.
