Methode for the evaluation of the stability of a welded assembly and corresponding apparatus for measuring the velocity of ultrasonic surface waves |
摘要 |
Ultrasonic waves are produced at the surface of a thin sheet metal (1) welded to a substrate (28): it has been observed that the propagation speed of the surface waves can thus be correlated to the resilience of the welded assembly to enable non-destructive controls.
