Laser Cladding FAQs - What is Laser Cladding? Benefits, Processes

In Laser Cladding process , a laser beam is used as the heat source to melt powder or wire based material onto the surface of another material or component giving a fully dense, homogeneous and metallurgically bonded coating layer.

The heat input in the laser cladding process is very low. It gives following advantages

Minimum distortion
Less heat affected zone
Minimum dilution of deposited
material in the substrate (typically <5%)

Laser Cladding is an automated Process. Automation gives us some advantages

Accurate control over heat input
Process stability and reproducibility is excellent
Near net shape cladding

Due to these factors, the coating is fully dense, homogeneous and has fine microstructure. Also, the coating forms a metallurgical bond with the base material, which does not wear off easily as compared to convection thermal spray coatings.

Depending on the desired surface properties a variety of materials can be deposited, some of them include: Cobalt based alloys (Stellites), nickel based alloys, Carbides (tungsten carbides), Iron based alloys to name a few.

Laser cladding is currently being used in the following areas Oil and gas industry, downstream drilling tools, Mining equipment, shafts , automotive components, agricultural tools, heat exchangers , shafts, valves, aerospace components to name a few.

Yes, laser cladding can be done in Internal diameter.
