MM-L300A Laser Weld Monitor

The high-resolution, compact MM-L300A laser weld monitor is designed to detect production errors such as gaps between parts, missing parts, over-penetration, incorrect focus and cover gas absence, providing operators feedback on resultant laser weld quality. The compact, lightweight unit supports laser welding technologies for spot or seam welds.

This high-accuracy laser weld monitor is ideal for both process development and quality control for production laser welding applications. The MM-L300A determines weld success by detecting and recording a thermal signal from the area of laser interaction and providing an output waveform around which limits (max/min or envelope) can be set.  Once the limits are determined, the unit compares a new weld waveform in real time to identify a good or bad weld. Providing high temporal resolution—down to 1 microsecond—the MM-L300A, with the SU-N300A dedicated...
