Investigate the welding of Inconel 718 and Inconel 600 in friction stir welding

This paper proposed the methodology of dissimilar welding of Inconel materials in Friction stir welding process. For the great mechanical and thermal properties the Inconel alloys are preferered. Inconel alloys are used in aerospace and petro chemical industries for its good thermal properties. The requirement for prudent and productive utilization of materials regularly requires the joining of different metals. This research analyse the, welding between Inconel 600 and Inconel 718, was endeavored to utilize rotating grating welding. The qulity of the weld is achived by the weld deposite without unwanted Laves or delta stages. Grain coarsening in weld affected zone was investigated by the weld thermal cycle. At room temperature tractable tests, the joints were found to fall flat in the HAZ of Inconel 718, showing great extreme elasticity (759 MPa) without a critical deficiency of malleable flexibility (21%). A filtering electron infinitesimal assessment of the break surfaces uncovered fine dimpled crack highlights, recommending a break in a pliable mode.
