Diffraction Echo Signal Separation
Diffraction-echo signal separation isolates weak crack tip signals from strong reflectors in ultrasonic testing to increase measurement reliability.
Physico-Chemical Mechanism of Action
The method separates weak diffraction signals from strong geometric reflectors through special signal processing techniques. This enables more precise detection and localization of crack tips.
Metallurgical Relevance & Welding Risks
In ultrasonic testing, weak crack tip signals can be overshadowed by strong reflectors, leading to errors in depth determination. Signal separation improves measurement accuracy and reduces the risk of misdiagnosis.
Workshop Practice & Action Instructions
Use ultrasonic equipment with diffraction-echo signal separation functions. Ensure that the equipment is correctly calibrated and the signal processing option is activated. If weak crack tip signals are suspected, conduct a detailed analysis to avoid misdiagnosis.
