摘要：
Rolls-Royce and Imperial College are developing phased array inspections for welded stainless steel piping with an undressed weld cap. An inspection that proves particularly challenging requires ultrasonic waves to propagate across the irregular weld-cap profile, and through the structurally complex weld material. Simulations of ultrasonic wave propagation through the weld region were obtained using the CIVA software to predict the effect on inspection performance. Simulated and experimental data was collected as Full Matrix Capture (FMC) which was then processed using our own software with results then displayed in a Beta version of CIVA. An investigation was conducted to confirm the principle of updating delay laws for variations in material properties.
