Types of Laser Welding Monitoring Systems
Laser welding monitoring systems are mainly divided into the following types:
Vision Monitoring Systems
These systems use cameras and image processing technology to monitor the welding process in real-time, identifying welding defects and anomalies.
Acoustic Monitoring Systems
By analyzing the sound waves generated during the welding process, these systems can quickly identify welding defects such as uneven welds and cracks.
Optical Monitoring Systems
These systems utilize laser scattering and reflection phenomena to monitor the temperature distribution and molten pool state in the welding area, ensuring welding quality.
Electrical Signal Monitoring Systems
By monitoring welding current and voltage, these systems can detect abnormalities in the welding process, such as arc instability.
