In addition, even with automated methods, when the location to be inspected is a weld bead, for example, it is impossible to place an ultrasonic probe for flaw detection at an accurate location in and around the weld bead. Even if it were tested, it was an undeniable fact that the accuracy would be greatly reduced.
