Abstract
The paper deals with weldability of a high-temperature nickel-base alloy with dispersion strengthening. It is shown that the alloy cracking resistance can be increased by optimization of the heat treatment mode before welding and lowering the cooling rate after welding.
Keywords: thermal hardening nickel alloys, -phase, arc welding, hot cracks, heat treatment, overageing, long-term strength
