Abstract
In the propulsion engineering it's expedient to spend welding of small thickness metal alloys by pulse laser radiation. It's established that formation of welded joint with strip power source gives possibility to increase the weld cross-section area and, as consequence, joint strength. At welding of high-temperature and heat-resistant nickel-based alloys {superalloys} strength of welded joint raises on 10...20 %. Carbides were dissolved, the cast zone has homogeneous structure without emptiness and blisters that specifies in high workability of welded joint.
