Abstract
PURPOSE:To detect for sure a defect at a weld by providing an internal truck that is freely movable on the inner face of a tube to be inspected in the inner circumferential direction and an outer truck that is freely movable on the outer face of the tube in the inner circumferential direction. CONSTITUTION:The inspection device comprises an intermal truck 9 that is freely movable on the inner face of a tube 3 to be inspected in the inner circumferential direction and has the end 8A of an optical fiber 8 fixed in the direction that is parallel to the axial line of the tube 3 to be inspected and a truck 10 that is freely movable on the outer face of the tube 3 in the circumferential direction and is free to follow said internal truck 9 by means of magnetic attraction developed between the internal and external trucks 9 and 10. With this arrangement the internal truck 9 is moved as the external tube 10 is moved, and if the opening 13A of a guide pipe 13 is placed on a weld 4, any defect in the weld 4 can be visually inspected by moving the external truck 10 along the weld 4.
