PURPOSE: An X-ray nondestructive inspection device of a pipe welding line is provided to regulate a gap between a rear surface of a welding line and a boom, thereby easily receiving X-rays in a photosensitive film. CONSTITUTION: An X-ray nondestructive inspection device(1) of a pipe welding line comprises a boom stand(40), a boom(10), an arm base(66), a support arm(50), a rotary driving unit(60), and an arm lifting-driving unit. The boom includes a stopping end portion(14) being supported by the boom stand, an entry end portion(16) entering into the inside of a target pipe, and a film attaching surface(12) where a film is attached along a longitudinal direction. One end of the support arm is installed in the arm base to be rotated, thereby being rotated between a portion, where the entry end portion is lifted, and a portion where the entry end portion is retracted. The rotary driving unit is installed in the arm base, thereby rotate-driving the support arm. The arm lifting driving unit lifts the arm base. |
