Abstract
Study of various microstructural properties and mechanical properties of the weld zones of different alloys, which were welded using the EBW and LBW. This study reveals all the changes occurring to the microstructural and mechanical properties due to variation in the input values such as at which speed the welding is done, the angle at which the component is welded. EBW is the most sophisticated process for welding both similar and dissimilar metals and alloys. As the process is a high energy density process, the heat produced or the heat input is comparatively lower than the convention welding process, thereby producing smaller width of the fusion zone (FZ) and heat-affected zone (HAZ). Due to the HAZ, the microstructure and microhardness of the Base Metal (BM) are getting affected. And the optical microscopy studies also revealed how the microstructure changes affect the microhardness and the tensile strength. Some of the test results were also incorporated to add strength to the details provided.
