Comparative Analysis of Microwave based Joining/Welding of SS304-SS304 using Different Interfacing Materials

Abstract

In recent years, researchers have developed methods for joining bulk metals like aluminium, stainless steel, mild steel, cast iron etc. through microwave radiations. The present work is based on the joining of stainless steel-304 with two different interface materials i.e. Nickel based EWAC powder and 99.9% pure Nickel based powder. The obtained samples were characterized by XRD, SEM and Rockwell hardness test on HRC scale. The experimental results show that the Nickel based EWAC powder is better in terms of weldability than 99.9% pure Nickel based powder.
