Laser Welding Monitor LWM

Production information

Laser Welding Monitor LWM

The Laser Welding Monitor LWM is a real-time monitoring system for series production and it provides online quality-relevant information about laser welding seam. It detects changes to welding parameters, deviations in the welding joint and lack of fusion. The welding process finger print is determined via the reference values of the plasma, metal vapor, temperature or laser radiation and compared to running production signals and transferred in real time.

In-process monitoring system for solid-state, diode and CO₂ lasers.
Self-sufficient real time measuring system.
Suitable for various welding processes (keyhole welding, heat conduction welding, pulse, CW laser).
Provides exposure about welding depth, seam position, pores, splashes etc. in connection with the welding process.
Provides established process and possible error correction.
Contact-free signal recording and evaluation methods in line with the process.

Number of digital inputs / outputs	16 each
Number of programs / expanded to	32/128 to 256
Number of parallel processing data channels	max. 8
Number of detectors	max. 16
Sample rate of detectors	max. 40 kHz
