Hardfacing is the process to apply a tougher material to a base metal, to make it more durable or extend its lifespan. This harder material is welded to the base metal by using specialized electrodes or filler rods.
They are meant to form very dense and thick layers (between 1 to 10 mm) above the base metal of wear-resistant material with high bond strength. The coating material can add ductility, hardness, corrosion resistance, and erosion resistance to the original part.
Other names given to hardfacing are hard surfacing, surface welding, and cladding. Among the base metals that can be hardfaced are the following ones:
Cast Iron
Copper-base Alloy
Nickel-base Alloy
Stainless Steel
Manganese Steel
Carbon and Alloy Steel
WE TAKE HARDFACING JOB FOR ALL KIND OF PARTS
Why hardfacing may be needed?
All metal parts even with normal use will wear as time goes by. This may cause them to lose their functionality and as a result, the need for a new part.
In certain industrial applications, like in mining or agriculture, this may happen more frequently. Hardfacing can be an ideal option for any metal part that may wear for being used. In short, hardfacing can help to:
Spend less downtime for replacing worn or broken components
Store fewer spare parts to inventory, because they are not needed
