Abstract
Lamb waves are a type of ultrasonic waves has a wide range of applications in non-destructive testing. Most of the studies used simple and flat structures for breaking, cracking or corrosion damages. In this study, the detection of damage in the welding is examined. Two 4.5mm thickness AL2024 plates joined by overlay welding method. Damage was applied to the weld region gradually. Three piezoelectric (PZT) discs were used to create surface waves and to monitor their propagation. For better examination, the envelopes of the monitored signals were calculated by using the Hilbert transform. Damages occurring in the weld region, has led to reflections and attenuation in waves. The study indicated that degradation occurring in the weld can be identified with the Lamb wave technique.
