What is Hardfacing?
Hardfacing is a metalworking process of applying tougher metals, high-temperature alloys, ceramics and other overlays to base metals to enhance standard wear, corrosion, hardness and other physical and chemical characteristics of the base metal.
When to Hardface?
Hardfacing can be applied at during all life-cycles of a fabricated or machines part. Commonly, hardfacing is applied
- On new parts to increase wear
- On older, worn-down surface back to tolerance
- On functional equipment to extend the life of fabricated components as part of maintenance program
How is the Hardfacing applied?
There are a variety of methods to apply hardfacing. No one method is superior to others, rather the method is recommended based on the intended purpose of the hardfacing. Some of the more common welding methods include:
- Shield Metal Arc Welding (SMAW)
- Gas Metal Arc Welding (GMAW)
- Oxyfuel Welding (OFW)
- Submerged Arc Welding (SAW)
- Electrical Welding (ESW)
- Plasma Transferred Arc Welding (PTAW)
- Thermal Spraying
- Cold polymer compounds
- Laser Cladding
Hardfacing has been incorporated into the procurement and maintenance programs for a variety of industries including, but not limited to, Steel, Cement, Mining, Petrochemical, Power, Sugarcane and Food, Process Chemical, as well as general manufacturers.
