Laser Welder

LW1089

Product Description

The Laser Welder LW1089 is a system for deep penetration welding of aluminum and copper leads on DCB substrates, used in power electronics and battery cells. It allows for different weld geometries and depths through laser power modulation. A movable holding-down device provides zero-gap detection and prevents contamination from weld splashes. High axis accuracy and process control ensure precision and reproducibility. The “clamp and weld” concept allows fast adjustment to different product variants and flexible changeover, accommodating component tolerances.

Key Features

  • Large working area: 400 mm × 400 mm × 75* mm (X×Y×Z)
  • Fast weldng times
  • Different weld geometries and depths due to temporal and spatial laser power modulation
  • Active vertical axis with sensor technology
  • Sensor for touchdown detection in combination with an adjustable hold-down force avoids damage to sensitive contact partners
  • 1.5 kW laser beam source
  • Image recognition (PR) for precise detection and correction of the weld location
  • Minimal mechanical and thermal load
  • Process monitoring via sensors for process illumination (plasma, thermal illumination and backscattered radiation)
  • Standardized interfaces for line integration
