Abstract

The principles of welding with pressure for making nuclear reactor components from refractory nickel alloys with limited weldability are presented. The main focus is placed on gasostatic diffusive welding with additional surface treatment (laser surface modification and profiling by machining). It is shown that the modification of welded surfaces allows making the breaking strength of the weld joint at room temperature closer to that of the base metal.
