The welding powders are produced by advanced
gas atomization and water atomization equipments --gas(high purity Nitrogen)
cooling technology, and by this technique the powders are uniform, low in
oxygen and spherical in powder. The powder particle size of the company is
uniform (the size can be controlled), the specifications are complete, and the
quality is unanimously approved by the user. Applicable processes are including
PTA overlaying and spraying, laser overlaying，HVOF etc. These powder can be wildly used in
High-temperature and High-pressure valve, Valve seat, Engine valve, Internal
combustion engine inlet/outlet valve, Gardening tool, Turbine blade, Bearing
and Hot cutting edge etc.
The commonly used welding powders are shown
in the table (if customers have special surfacing welding process requirements
can be customized)
