Abstract
Causes of hot cracking of the weld metal in fusion welding of high-alloyed heat-hardenable nickel-base alloys have been analysed. It is shown that recommendations available in literature on elimination of cracks are applicable only for alloys with a low content of the γ′-phase. Ways of solving this problem for alloys with a high content of aluminium and titanium are indicated.
Keywords: arc welding, heat-hardenable nickel alloys, γ′-phase, hot cracks, chemical composition, relaxation resistance, heat treatment, filler wire, strength
