Abstract: A carriage for inspecting the integrity of a spiral weld in a tubular is arranged to be driven axially within the tubular by the weld as the tubular is rotated. The carriage includes one or more transducers for transmitting to and receiving data from the weld.

Abstract: An ultrasonic inspection system useful for inspecting a tubular member provides for the use of ultrasonic transducer assembly for detecting weld flaws or other out-of range conditions in the tubular member. According to the invention, the tubular member is positioned horizontally on a rolling carriage and a predetermined amount of sound-conductive fluid is deposited into the tubular member. Wide rings secured to opposing open ends of the tubular member prevent the liquid from escaping, while forming a barrier for retaining a given level of liquid inside the tubular member. The transducers are submerged in the liquid and transmit/ receive sonic booms from reflected medium inside the tubular member. The transducers are connected to a computing control unit, which receives signals generated by the transducers and creates a report of any out-of range condition.
