Abstract:
An apparatus for the concurrent inspection of partially completed welds, comprising:a moveable welder for forming a partially completed weld; an ultrasonic generator mounted on the moveable welder and which is reciprocally moveable along a path of travel which is laterally disposed relative to the partially completed weld; and an ultrasonic wedge oriented in ultrasonic signal receiving relation relative to the ultrasonic generator, and wherein the ultrasonic wedge comprises first and second materials, and wherein the speed of an ultrasonic signal generated by the ultrasonic generator traveling in the first material varies to only a small degree as a function of increasing temperature, and wherein the second material has an ultrasonic attenuation which is large in relative comparison to the ultrasonic attenuation in the first material.
