Amada Miyachi Announces MM-L300A Laser Weld Monitor
Amada Miyachi Europe has announced the availability of the new MM-L300A Laser Weld Monitor. The compact MM-L300A is designed to detect welding defects and errors such as gaps between parts, missing parts, weld depth over-penetration, incorrect focus point and cover gas absence. It is providing operators feedback on the resultant laser weld quality. The compact, lightweight unit supports laser welding technologies for spot or seam welds.
This high-accuracy monitor is ideal for both process development and quality control for laser welding applications. The MM-L300A indicates weld quality by detecting and recording a thermal signal from the area of laser interaction and converting this into a graphical waveform. Part of the intelligence of this third generation process monitor is that not only absolute max/min limits can be set but also value envelopes can be drawn around the waveform. 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, 3 kg (7 lb) 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 of the laser beam trajectory or in an off-axis position.
