Laser Softening & Glühen
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 / Glühen?
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.
Hauptmerkmale
