Nickel-based welding alloy also contains (preferred wt%): chromium 7.5 - 11; cobalt 8.0 -11.4; tungsten 2.8 - 6.9; melting point lowering agent 3 - 19.4; and at least one component chosen from scandium, zirconium, aluminum, titanium and tantalum. An independent claim is included for a method for repairing components (1) using the alloy (10) which is carried out at a uniform temperature or using a temperature gradient.
