Laser Cladding

Industries that utilize laser cladding: Oil & Gas, Mining, Petrochemical, Power Generation, Rail transport, Shipping and Dredging, Agricultural, Construction.

When you need durability, laser cladding is the modern ‘go to’ method to multiply the lifespan of your parts, instead of traditional welding.

LASER CLADDING CAPACITY

At our south Edmonton location, Group Six has the ability to apply cladding on the outside and the inside of components.

INTERNAL CLADDING

Our internal cladding can reach 36” (914mm) into a bore as small as 2-3/8” (60mm). This laser is used on the internal surfaces of components to repair internal profiles, build wear resistant surfaces, and harden select surfaces. With a 1/8” (3mm) spot size we can also do external cladding on smaller or complex components. Some examples of this would be ball pockets in driveshaft adaptors, repairing seal surfaces on drilling tools and pumps, and the application of tungsten carbide surfaces for flow restrictors.

EXTERNAL CLADDING

With our W.I.D.E laser cladding head we can cover large areas quickly and efficiently by cladding with approximately ½” (12mm) wide passes. This laser can handle parts up to 35 feet long and diameters of up to 24” and a variety of non-round parts. Typical uses here include bent housing pads and hard bands on drilling tools.

OVERALL ADVANTAGES OF LASER CLADDING:

  • The process is repeatable and efficient
  • Laser cladding creates a metallurgical bond between the base material and the overlay that will not flake away.
  • A very low total heat input which allows for virtually no distortion of tight tolerance components.
  • A very wide choice of different materials can be both deposited and deposited onto.
  • Deposits are fully fused to the substrate, creating a smooth clad with little or no porosity.
  • Minimal heat input results in a narrow heat affected zone (HAZ).

LASER CLADDING VS. TRADITIONAL WELDING

Group Six uses robotic laser systems to provide precision control during the cladding process. The accuracy and repeatability of these systems provides significant process control advantages over traditional, manual welding.

Unlike welding, laser cladding provides a strong metallurgical bond with minimal dilution of the base material, exceptional thickness control, and a small heat affected zone.

From a cost perspective, other methods of cladding application, such as PTA, have been seen as ‘less’ expensive. But in fact traditional welding adds costs to the part over its lifespan. Meanwhile, laser cladding can triple the life of a part and dramatically reduce investment in new parts.

TYPICAL LASER CLADDING APPLICATIONS

Laser cladding is ideally suited to create an entirely new surface, or to repair damaged or worn surfaces. Laser cladding can create functionally graded coatings where the material composition of the coating can be changed, which results in material properties tailored to particular areas of components.
