Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The LW1089 is a fully automatic laser welding system with a large working area. The LW1089 is designed for fully and semi-automatic deep-penetration welding of aluminum and copper leads on DCB substrates. The LW1089 has a laser beam source with max. power of 1.5 kW.[1][2]
What it is
How it works
The LW1089 uses a laser beam to create intermetallic joints along a weld seam.[1][2]
The LW1089 uses temporal and spatial laser power modulation to produce different weld geometries and depths.[1][2]
The LW1089 includes an active vertical axis with sensor technology, touchdown detection, adjustable hold-down force, monitoring optics with ring light and image recognition, and process monitoring via sensors for process illumination and backscattered radiation.[1][2]
