Powder Welding (Fuseweld)

Copper Phosphorus brazing alloys

Applications

Powder welding process is particularly suitable for small parts, repairs and maintenance.

A standard oxy-acetylene torch with integrated hopper feeds hardfacing powders on the work piece into flame. Hardfacing takes place relatively at lower temperatures. Dense coating of powder forms a strong bond to the base metal by alloying and diffusion.
