Laser Hardening Technology – A Precise and Modern Surface Hardening Solution Laser Hardening is an advanced heat treatment technology that uses a high-power laser beam to locally heat the surface of a metal component to its hardening temperature, followed by self-quenching using the material’s own mass. This process creates a ...

Repair the roller shaft by Laser Cladding is the most advanced technology today. It is quick to repair, and saving cost and time. In addition, depending on the working conditions, it is possible to choose suitable powders to increase service life, resist wear and corrosion… We specialize in providing welding, ...

Bearing-mounted shafts are often quite diverse in terms of materials and sizes. After the working process, the shafts usually will be abrasive, scratched the surface due to disassembly, or chemical reaming. Solution: coating the suitable material, then machining to become the original size. Currently, Laser Cladding technology is the most ...
