Desktop Welding Monitor

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

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

The MM-L300A features easy-to-use software for simple sensor configuration, waveform envelope limit set-up, and real-time or saved waveform analysis on Windows PCs. Plus, with machine-selectable setup schedules, the unit can monitor different welding conditions. For process design flexibility, this approximately 7 lb. system reduces set-up space when integrated into a production line, and the sensor mounts either on the optical axis of the laser or in an off-axis position.
