The invention relates to a method for inspecting a weld by radiography, said method comprising the following steps: - assigning a unique identifier (20) to the weld before being inspected, - writing a unique alphanumeric identifier (12) and the unique identifier (20) of the weld on a label (5), with at least the alphanumeric identifier (12) being written in a manner that is visible to the naked eye. - including on a support plate the same alphanumeric identifier (12) as that written on the label (5), said identifier being invisible to the naked eye and composed of elements that are opaque to x-rays and gamma rays, - installing the support plate at the weld and taking a radiographic image (3) of the weld and support plate assembly, - attaching the label (5) to the radiographic image (3) taken, - developing the radiographic image (3) taken, in such a way that the alphanumeric identifier (12) becomes visible to the naked eye on said image, - checking that there is a match between the alphanumeric identifier (12) visible to the naked eye on the developed radiographic image (3) and the alphanumeric identifier (12) written on the label (5). |
