Welding of the high-temperature strength and heat-resistant nickel basis alloys by pulse laser radiation

The parameters of a mode providing qualitative connection of scarf welding nickel basis alloy ХН70ЮШ (ЭИ652) by thickness of 0,4 mm at influence pulse-periodic radiation on the laser setup StarWeld Manual Performance are experimentally determined. Metallographic researches of the metal seam structure in the cross-section of laser welding zone have allowed to establish that the seam has homogeneous structure without emptiness and bowls. The maximal ultimate load at carrying out tests for static durability has made Р = (8,5…9,0).102 N.
