ABSTRACT:
Apparatus for inspecting a part by means of X or gamma radiation comprises an arm carrying an X or gamma ray emitter, and a remote light ray emitter for emitting a ray of light parallel to the arm. An oblique mirror which is transparent to the radiation is mounted on the arm in the path of the radiation beam to reflect the ray of light in a direction parallel to the radiation beam and towards the part to be inspected. In this manner identification of the part to be inspected can be achieved by means of a camera carried obliquely on the arm, without having to mount the bulky light emitter close to the components which are essential for carrying out the inspection. The apparatus is particularly useful for checking weldings in narrow bores.
