The MM-L300A laser weld monitor helps to ensure weld quality and maintain high throughput by providing realtime feedback during the laser welding process to ensure weld success. MM-L300A works by detecting and recording a thermal signal from the area of laser interaction during the welding process. The SU-N300A thermal sensor samples the signal and provides an output waveform around which envelope limits can be set.
The MM-L300A can detect the following production errors:
Gap between parts Missing part Out of focus Absence of cover gas
High temporal resolution (down to 1 µs) with a dedicated sensor, enables monitoring of both CW and pulsed lasers
Envelopes allow real-time comparison and detection of good and bad welds
Light weight, compact design reduces set-up space when integrating into production lines
Sensor can be mounted either on the optical axis of the laser or off-axis
Easy and intuitive operation.
