APPLICATIONS FOR STELLITE CASINGS, NICKEL-BASED LINERS AND CARBIDE ACTUATOR STEMS Material performance is essential for the engineering and manufacturing of industrial valves to increase service conditions in demanding environments like off-shore, oil and gas, mining, dredging and process industries. Weld-overlay and hard-facing are commonly used for Stellite reinforcements or nickel-based liners like Inconel or Hastelloy. LCV offers enhanced laser cladding solutions which set a new standard in terms of performance and cost. As a valve manufacturer, laser cladding offers you increased wear resistance, more efficient material application and reduced cost of the weld-lay-up due to LCV’s proprietary FastCLAD technology.

1. Laser Cladding for Valve Manufacturing

2. Thermo Spray (ex. HVOF)
• Mechanical bond
• Porosity and micro structure defects
Hard Facing
• Metallurgical bond
• Dissolved carbide structure, high-

Laser cladding is a weld overlay technique where
metallic powder is metallurgically joined to
substrate by means of laser generated energy
Metallurgical bond  increased durability
Minimal heat input  limited deformation
•Fine microstructure -> extra hardness
