Spray Fuse and Powder Welding

Kennametal Stellite™ powders are gas atomised powders.

A specially designed Oxy Acetylene torch is used for powder welding. The work piece is heated with the torch. The powder is introduced into the gas stream from the integral powder hopper and then transferred to the work piece through a flame.

This process is similar to the Oxy Acetylene process with the exception that the hardfacing takes place at lower temperatures. This minimises oxidation and distortion of the work piece ad enables easy surfacing of edges.
