Investigation of Stainless Steel Joint Fabricated Through Microwave Energy

In this paper, the microwave heating has fabricated joints of stainless steel (SS). Ni-based powder (EWAC 1002 ET) is used to join the stainless steel. The characterization of joint has been carried out through microstructural analysis, X-ray diffraction analysis, tensile strength, elongation, and microhardness. Microstructure analysis reveals that the joint is clearly visible. There are no cracks at the joints. Very small amount of porosity has been observed. Hardness decreases toward the joint. As the exposure time and percentage of nickel-based powder increase, tensile strength also increases. Tensile strength, elongation, and microhardness of joint are 323.16MPa, 11.30%, and 145.3Hv, respectively.
