High resolution laser weld monitor
- June 11, 2019
Amada Miyachi America has announced the new MM-L300A Laser Weld Monitor.
The high-resolution, compact MM-L300A provides 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 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 monitor, equipped with the SU-N300A dedicated thermal sensor enables precision monitoring of both CW and pulsed lasers.
The MM-L300A software supports sensor configuration, waveform envelope limit setup and real-time or saved waveform analysis on Windows PCs. Also, with machine-selectable setup schedules, the unit can monitor different welding conditions. For process design flexibility, this approximately 7 lb (3 kg) system reduces setup 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.
