Process Monitoring via Photodiode
A photodiode monitors the weld pool by capturing the emitted radiation and detecting defects in real time.
Physical-Chemical Mechanism of Action
The photodiode detects light or infrared radiation emitted by the weld pool. It converts this radiation into electrical signals.
Metallurgical Relevance & Risks in Welding
This monitoring helps detect defects like porosity or incomplete penetration. Missing detection can lead to poor weld quality that has to be fixed later.
Workshop Practice & Instructions
Install the photodiode near the weld pool and make sure it has a clear view of the weld zone. Regularly check sensitivity and calibrate settings for optimal defect detection.
