Melt Pool Geometry Monitoring
The melt pool geometry monitoring tracks the shape and size of the weld pool in real time to catch process instabilities early.
Physical-Chemical Mechanism of Action
Weld pool geometry monitoring uses optical or sensor-based sensors to continuously capture the shape and size of the weld pool during the welding process. This data is evaluated in real time to detect any changes in the weld pool.
Metallurgical Relevance & Welding Risks
An irregular weld pool can lead to inconsistent weld dimensions and strength. This increases the risk of cracks, distortion, and component failure. Early detection through geometry monitoring allows for quick corrective actions to minimize these risks.
Workshop Practice & Action Guidelines
To set up and use weld pool geometry monitoring:
1. Install optical or sensor-based sensors on the weld pool surface.
2. Connect the sensors to a real-time analysis device for data processing.
3. Set threshold values for weld pool shape and size to detect deviations.
4. Continuously monitor the data and respond to detected instabilities by adjusting process parameters such as voltage, current, or temperature.
