Hard Facing Materials
- Hardfacing Powders & Wires Description:
1) Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and is generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and TIG welding.
2) Hardfacing may be applied to a new part during its production, or it may be used to restore a worn-down surface.
3) Hardfacing by welding is a surfacing operation to extend the service life of industrial components, pre-emptively on new components, or as part of a maintenance programme. The result of significant savings in machine down time and production costs has meant that this process has been adopted across many industries such as Steel, Cement, Mining, Petrochemical, Power, Sugar cane and Food.
4) Extensive work in research has resulted in the development of a wide range of alloys and welding procedures. The optimum alloy selection is made considering the component service conditions and feedback of the service performance.
5) For each industrial application and wear phenomena, there is a welding wire to provide wear resistance. Source: Wikipedia
- Hardfacing can save your company time and money by:
- Extending the useful life of your hardware.
- Selectively applying the hard alloy only where it is necessary instead of making entire pieces from very hard materials.
- Reduces inventory costs by requiring fewer replacement parts on hand.
- Reduces equipment downtime.
