Pyrometric Process Monitoring
Pyrometric process monitoring is the non-contact measurement of the molten pool temperature in real time using optical sensors. It detects thermal anomalies and process instabilities quickly to improve quality control.
Physical-Chemical Mechanism of Action
Pyrometric process monitoring uses optical sensors that capture radiation from the weld pool and convert it into electrical signals. These signals are then interpreted to determine the temperature.
Metallurgical Relevance & Welding Risks
Inaccurate or slow measurements can lead to thermal anomalies, such as strong temperature fluctuations in the weld pool. This causes uneven melting and can lead to porosity or inconsistency in the weld. Quick detection of these anomalies by pyrometric process monitoring prevents such issues and ensures higher weld quality.
Shop Practice & Action Guidelines
To use pyrometric process monitoring effectively, sensors must be correctly calibrated and positioned at the right spots in the weld pool. Measurement data should be monitored and logged in real time. If deviations from normal temperature curves occur, immediately analyze and adjust process parameters if needed.
