Abstract
In a method for welding age-hardenable nickel-base alloys, a workpiece (5) made from an age-hardenable nickel-base alloy (1, 2) is welded with filler material of the same composition as the base material. The weld metal (3) which is formed in so doing is covered by a sealed covering layer (4) comprising a ductile material and the workpiece (5) is subjected to hot isostatic pressing (HIP).
