Laser Cladding Machine

This laser cladding system is probably the first of its kind in India. Featuring a 2.8 KW fiber coupled diode laser and a coaxial powder-feeding nozzle for porosity free, and near crack-free nickel-based coatings; high content globular tungsten carbide (WC) get applied to metal surfaces. The process reduces the operational cost of conventional CO2 systems by at least a factor of three, and lowers investment cost by utilizing smaller laser systems.

Our laser cladding system is extremely compact in size, easy to operate, has high wall plug efficiency, lower investment and running costs for laser cladding; especially in an industrial environment.

The laser cladding principle:

A metal surface-enhancing process performed by applying a powdered metal material on to the base surface, forming a laser bond with minimal dilution, nominal melting and small heat affecting zone.

Laser cladding features:

  • High bonding strength
  • Low dilution
  • Metal and ceramic coating materials
  • 50 mm to 2 mm coating thickness
  • High repeatability low heat affected zone (HAZ )
