DLAMP is a revolutionarily joining technology for metal and dissimilar materials by use of laser.
Secure joint with dissimilar material is achieved by creating anchor structure on the metal surface by laser treatment.
- Features
- 1. Applicable to various metal
- 2. No masking is required for partial treatment (Single-side treatment and patterning is possible)
- 3. Small environmental load (No chemical waste)
The Mechanism of DLAMP
Anchor Effect :
The high joining strength is achieved by molten materials permeating through the voids (undercuts and tunnel-like structures) formed on the metal surface by DLAMP treatment.
