Description

One factor which influences the performance of ultrasonic examinations is the condition of the surface of a component through which the ultrasound must pass to enter the material. Often in nuclear reactor components, factors such as weld overlays, claddings, and diametrical shrink can give part surfaces a wavy, corrugated, or abruptly stepped topography. Having to pass an ultrasonic probe over such a surface during an inspection can result in a redirection of beam energy, beam partitioning, or possibly a partial truncation of the beam. These factors could leave regions of the part uninspected or give rise to mislocation of defects or geometrical reflectors.
