Why Laser Welding?

Laser welding offers superior process control and weld integrity compared to conventional joining methods:
  • Generates a narrow and controlled heat-affected zone (HAZ), reducing thermal distortion and residual stress
  • Supports deep and consistent weld penetration with precise energy delivery
  • Supports similar and dissimilar metal welding, including challenging metals like copper and aluminum, minimizing intermetallic compound formation
  • Preserves mechanical integrity and material properties across welded joints
  • Facilitates clean and precise fusion with minimal post-weld finishing requirements
  • Fastest welding technology enabling single-pass high-speed welds without the need for fillers or electrodes.
