DLAMP is NEW joining technology for metal and dissimilar materials.

DLAMP technology promotes multi-material and contributes to weight reduction.

Direct boding improves high reliability.

Direct bonding technology achieve a new solution.

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.

Laser surface pre-treatmentjoining technology for metal and dissimilar materials
Features
  • 1. Applicable to various metal
  • 2. No masking is required for partial treatment (Single-side treatment and patterning is possible)
  • 3. Low running cost

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.
