Automated TOFD Data Evaluation
Automated TOFD data analysis is a computer analysis of time-of-flight diffraction data that automatically detects and classifies internal defects.
Physical-chemical mechanism of action
The TOFD method (Time of Flight Diffraction) measures the time it takes for ultrasonic waves to reflect at a defect. Automated evaluation uses specific algorithms to analyze this data and detect potential internal defects.
Metallurgical relevance & risks in welding
Automated analysis improves defect detection accuracy and saves time. However, incorrect settings or missing calibration can lead to false alarms, resulting in inaccurate defect assessment.
Workshop practice & action instructions
Ensure the TOFD device is correctly calibrated and measurement data is regularly reviewed. Use specialized software for automated evaluation and interpret results critically. If necessary, conduct manual checks.
