Advanced Laser Weld Monitor



AMADA WELD TECH has launched the MM-L400A Laser Weld Monitor, designed to enhance precision and reliability in laser welding processes. This monitoring system represents a significant upgrade from its predecessor, featuring the ability to detect infrared (IR), reflected and visible light, providing comprehensive analysis of weld quality.

The MM-L400A provides in situ judgment of weld quality by monitoring workpiece gaps, surface conditions and focus accuracy. Utilizing its advanced capabilities, the system can differentiate between good and bad welds through a comparison of data, making it a useful tool for maintaining high-quality production standards. This feature is particularly beneficial in production lines, where consistent weld quality is critical.

The MM-L400A is equipped with the company's proprietary MS-Viewer software, offering a user-friendly interface that simplifies settings, adjustments and measurements. Users can easily adjust the measurement start trigger, sensor sensitivity, envelope settings and compare measurement waveforms. The software's intuitive design makes it accessible even to those unfamiliar with monitoring equipment.

The monitor's light-receiving unit can be integrated with AMADA WELD TECH's focusing units or scanner heads, providing flexibility in monitoring different welding processes. This feature is particularly useful for detecting penetration during scanner welding, making it a versatile tool for various applications.

Additionally, the MM-L400A's lightweight and compact design makes it easy to incorporate into existing production lines, minimizing the required set-up space. The system supports high-speed resolution with dedicated sensors, making it suitable for monitoring continuous wave (CW) and pulsed lasers. Furthermore, its ethernet communication protocol allows for remote monitoring and data management across production lines.

Data is stored in a database for easy access and further data analysis in SPC or OEE programs.

The MM-L400A complies with CE marking requirements, ensuring it meets the highest safety and quality standards. This advanced monitoring system is suited for manufacturers seeking to ensure weld quality and perform preventive maintenance, enhancing overall production efficiency and product reliability.
