What is the maximum scanning speed during the ultrasonic examination of a weld?

The maximum scanning speed during ultrasonic examination of a weld is significant because it impacts both the quality of the inspection and the ability to detect discontinuities within the weld. At a scanning speed of 6 inches per second, the ultrasonic waves can effectively penetrate and reflect off the welded joint, providing accurate data for assessing weld integrity.

Higher scanning speeds risk missing critical defects due to the reduced interaction time of ultrasonic waves with the weld material. The choice of 6 inches per second strikes a balance that allows for sufficient resolution and detection capabilities while ensuring that the inspection process remains efficient. This established limit is rooted in industry standards and ensures that operators can achieve reliable results during ultrasonic testing.
