High-resolution weld monitor
- June 17, 2020
The compact, lightweight unit supports laser welding technologies for spot or seam welds, providing operators feedback on resultant laser weld quality.
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 to set limits (max/min or envelope).
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 thermal sensor, enables precision monitoring of both continuous wave and pulsed laser processes.
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. Additionally, machine-selectable setup schedules enable the unit to monitor different welding conditions. The compact, 7 lb (3 kg) unit reduces set-up space when integrated into a production line or used in a laboratory environment. The sensor can be mounted either on the optical axis or in an off-axis position.
