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.
Spray-Fuse & Powder Welding are available in these standard size ranges:
Spray-fuse powders are available in these standard size ranges:
- M 106/45 µm (Metco torch)
- S 106/38 µm (Eutectic torch)
Powder Welding powders are available in these standard size ranges:
Please see the table below for details of our Spray-Fuse & Powder Welding powders.
Note – the hardness of the weld deposit may vary from that provided depending upon the process parameters and extent of dilution.
