Laser power monitoring system LWM 4.0

The Laser Welding Monitor LWM 4.0 is used for the online process monitoring in many areas of industrial production in 24/7 operation. In series production, it detects and documents a wealth of quality and productivity relevant information to the laser welding seam. The monitoring system detects typical welding defects such as: • Gap between upper and lower sheet • Change of laser power and focus position • spatter and pores that can occur during the welding process • contaminated components Thus, quality fluctuations caused by component tolerances, contamination, or different material batches can be monitored and detected. Advantages • 100 % traceability and transparency The system is easy and intuitive to use and provides you with helpful data on your laser welding seam. The allocation to each component is done via communication with the system control/SPS. All data is stored and documented continuously, even during ongoing production. In combination with online backups, the LWM 4.0 thus enables 100 % traceability and transparency of your laser welding processes - even after many years. • Reduction of reworking The reliable complete solution detects changes in welding parameters, deviations in the weld seam, and binding defects. Component deviations such as burr at the weld joint or faulty clamping devices are detected, as well as deviations in the welding depth. The fingerprint of the welding process is determined, compared with the signals of your current production, and transmitted in real time. Thus, welds can be specifically classified and rejected in case of abnormalities. This is a significant contribution to the reduction of rework.
