Radiation detection system

opticallaser

Product Overview
During laser welding the process emits optical signals (plasma radiation, molten-pool thermal radiation and laser back-reflection). Photodetectors convert these optical emissions into electrical signals and high-rate data acquisition builds a reliable signal envelope. By analysing variations of electrical signal parameters throughout the weld, the system evaluates weld quality and detects defects in real time.

Product Advantages

• Independently developed industrial solution designed for cost-effective integration into production lines.
• Accurate quality monitoring using an embedded welding process database and molten-pool analysis.
• Wide welding-head compatibility: supports collimation + focusing heads and galvo heads.
• Configurable and fast to deploy with tailored options for different applications.
• Seamless communication: supports I/O, Ethernet and industrial buses (including EtherCAT).
