Laser Softening & Recuit
Laser softening is a localized heat treatment process that reduces material hardness and relieves internal stress by controlled laser heating.
It improves ductility, toughness, and machinability without affecting the entire component.
- Local hardness reduction
- Stress relief after welding or cladding
- Improved machinability for secondary processing
What Is Laser Softening / Recuit?
Laser softening, also referred to as laser annealing or laser tempering, is a thermal process in which a laser heats the material to a controlled temperature below the hardening or melting point.
The process modifies the microstructure, reduces hardness, and increases toughness while maintaining dimensional stability.
Key characteristics:
No melting, no coating
Localized treatment only
Hardened surface + tough core
Why Laser Softening Instead of Conventional Heat Treatment?
- Localized Treatment — Only the target area is heated, leaving surrounding material unaffected.
- Minimal Distortion — Low overall heat input reduces warping and dimensional changes.
- Process Flexibility — Suitable for selective softening on complex or assembled components.
How Laser Softening Works
A laser beam heats the material surface to a controlled temperature range, allowing microstructural transformation and stress relaxation.
Heat dissipates naturally into the surrounding material, resulting in controlled cooling without quenching.
Caractéristiques clés
No melting, no material removal
Controlled temperature and heating depth
Repeatable and programmable process
