In welding technology, laser welding is an emerging and rapidly developing technique. During the laser welding process, signals such as metal vapor, laser reflection, and thermal radiation from the molten pool are generated. These emitted light signals can reflect the state of laser welding and whether there are any welding quality defects during the process.
The Welding Defect Detection System (WDD) utilizes photoelectric sensing technology to monitor the laser welding process in real-time. It converts the optical radiation generated during welding into electrical signals. By analyzing these signals through the laser welding detection system, information about welding quality defects can be obtained, thus achieving the purpose of online defect detection and quality control.
The welding defect detection System adopts a high-precision, highly integrated product design concept. The system integrates three major modules: multiple optical signal sensors, a signal processing module, and an operating system, greatly simplifying the difficulty of product installation and debugging, thereby reducing the cost of use.
