The Joining Technologies Laser Additive Division uses laser cladding processes to enhance or repair metal components for power generation, oil & gas, power generation, industrial equipment, petrochemical and aerospace. Enhanced or repaired components include ball valves and seats, super heater water panels and tubes, IGT blades and vanes and a growing assortment of parts for many new customers. Our ultra-equipped cladding facility is home to the country’s leading laser applications engineers, developing laser clad solutions for components from as small as a marble to over 40 feet long.

Our Laser Cladding facility in East Granby Connecticut offers our clients the ability to perform robotic and Cartesian laser cladding for components from the very small up to 40ft and 7.5 tons.

Laser Cladding, Laser AdditiveWhy Laser Additive

The unprecedented precision and reliability of our laser cladding processes is now available to private industry. As a leading provider of LAM (Laser Additive Manufacturing) surface restoration technology, we’re able to create true metallurgical bonds between virtually unlimited metal types. Precisely focused lasers enable us to create extraordinarily small heat-affected and dilution zones for superior strength, hardness and performance.

APPLICATIONS:

Joining Technologies uses laser cladding of metal powder alloys to enhance or repair components for aerospace, power generation, valves and OEM-supplied components. Our laser additive processes offer cost effective positional accuracy, material quality and metallurgical bonding.

The Laser Advantage

Laser Additive ManufacturingThe laser additive manufacturing process known as laser cladding uses metal powder alloys to enhance or repair metal parts. Using a laser to create a melt-pool on the workpiece, powdered metal is fed through a nozzle into the weld puddle, creating a clad layer. Unlike HVOF, the laser clad process achieves a full metallurgical bond by fully melting the surface of the substrate while applying powder. The precisely targeted heat of the laser allows for lower penetrations of the parent material, resulting in a smaller Heat Affected Zone (HAZ) and a lower dilution rate. This translates to an enhanced grain structure and lower minimum clad thickness required to achieve desired hardness, as compared to PTA clads. Parametric accuracy of the system allows for clad layers as thin as 0.004”, with maximum clad thicknesses that are virtually unlimited.
