Laser Cladding & Laser Hardfacing

About Laser Cladding & Laser Hardfacing

Laser Cladding and Laser Hardfacing are additive manufacturing technologies utilizing the high energy of a laser to bond a high performance alloy to a metal substrate of typically lesser quality. The laser cladding layer is customized for protection against corrosion, wear, high temperature fatigue and other failure causing conditions. In laser hardfacing, additional hard particles are embedded into the layer to offer superior resistance against abrasive wear.

Laser Cladding

LWS will assist the customer in determining which laser cladding and hardfacing technique to use for their wear application. With more than 15 years of experience we will also recommend the right commercially available alloy or assist in the development of a proprietary, unique material solution.

Cost Savings Potential

Today laser cladding is an important cost savings tool as it significantly increases the lifetime of high performance components and at the same time reduces the use of rare and expensive metal materials.

Characteristics of Laser Cladding

The increasing popularity of laser cladding compared to conventional technologies such as thermal spraying (HVOF, Plasma, Cold Spray etc) and arc overlay welding (PTA, TIG etc) is driven by characteristics such as:

  • The high performance alloy is melted with minimal dilution of the lesser substrate material, thus preserving the qualities of the performance alloys.
  • The melt metallurgical bond between the completely dense performance alloy and the substrate is extremely strong and free of defects.
  • The heat input into the substrate is minimal thus not damaging important properties or causing heat related distortion.
