Abstract:In this paper, it was indicated that the laser welding was well suitable to joining of thin Hastelloy C-276 sheet(0.5mm thickness),and also the fine grain were observed in welding zone with invisible HAZ (heat affected zone). In addition, the smooth weld joint could be controlled by means of the laser parameter adjustment. On the other hand, it's proposed that Ni-Cr-Co-Mo and austenite CFe15.1 cubic face-centered crystal structure should be existed in as-received and welding samples, as well as the cause of FWHM (Full Width at Half Maximum) widened and peak offset of joined samples were analyzed.
