Inconel 625 is used for laser welding of Inconel alloy 625,
Inconel alloy 825, Inconel alloy 25-6Mo and a range of high
alloy austenitic and super austenitic stainless steels, often
used in the aircraft industry. It is also used for surfacing of
steel, for laser welding of 9% Ni steels and various corrosion-resistant alloys. Inconel alloy 625 has a good resistance
to oxidation and scaling at high temperature.
