The system provides first and second sensor assemblies and processor that work in cooperation to detect flaws in welded tubulars. The first sensor detects and provides an indication of the weld line to the processor, which analyzes the indication and determines the approximate location of the weld line along the tubular. The processor then transmits a signal to the second sensor assembly, which is preferably mounted on an automatic positioning apparatus. In response to the signal, the automatic positioning apparatus adjusts and readjusts the position of the second sensor assembly into proximity with the weld line to search for flaws in the tubular.
