Diode laser hardfacing is a welding overlay process that is applied to the material handling components to resist wear and prolong life; It is a unique laser cladding process that can apply a thin layer of welded metal with embedded super-hard particles producing extreme wear resistant coatings. This inherently low heat process produces low distortion, smoother, thinner and more uniform anti-wear coatings as compared to any other welding process. The lower heat does not burn out the carbides, achieving hard particle densities up to 75%.

Tungsten Carbide Laser Hardfacing
Tungsten carbide is the standard for high performance hardfacing. There are several reasons, beside hardness that Tungsten carbide is the hardfacing ceramic of choice, it is very chemically stable at molten metal temperatures and not as reactive as is the case with diamond [carbon]; it is has a very high density as compared to silicon carbide, titanium carbide, which means that it will not float on the molten metal.
Applications
- Metal components experiencing high intensity wear such as ground, rock, dust or sand engagement devices
- Down hole component for oil & gas– mud pump components
- Coal and ash handling equipment
Benefits
- Low heat input
- Fast cooling
- Negligible disassociation of carbides
- Stress free overlays
