ABSTRACT:
A filler for welding a heat-resistant nickel-base alloy is disclosed. The filler comprises heat-resistant nickel-base alloy and an additive of 0.003 to 0.015 wt % boron based on the total weight of the filler metal. The filler may further comprise an other additive such as zirconium in the total amount of those two elements of 0.015 to 0.15 wt %, and the filler may further comprise the other additives such as lanthanum and cellium in the total amount of those fine elements of 0.018 to 0.15 wt % based on the total weight of the filler. The disclosed filler has improved creep properties at high temperatures and can be obtained without the defects inherent to conventional filler of heat-resistant nickel-base alloys.
