ABSTRACT:
An x-ray probe carrier for the inspection of circumferential welds in cylindrical pipes includes a carriage supported on omnidirectional ball transfers for movement along the bottom of a pipe section. A centrally mounted adjustable probe holder is preset to coincide with the centerline of the pipe for single exposure x-ray examination of a full circumferential weld. The probe is maintained centered during travel along the pipe and is automatically recentered after travel through a horizontal bend. The probe holder is easily adjustable for use in a wide range of pipe sizes.
