Embodiment Construction

[0047] The following description refers to the inspection of pipe system welds. However, the present invention is still applicable to inspecting other types of welds, for example, inspecting welds of plates or other items.

[0048] figure 1 Different components of the support plate meeting the requirements of the present invention are described. The support plate comprises a hard shell 10 or a soft shell, eg a molded shell of opaque plastic. For example, the housing has a rectangular shape with a length of about 5 cm, a width of about 4 cm, and a thickness of about 3 mm.

[0049] The housing 10 has a recess 11 ; said recess can be used to place an assembly 120 of an alphanumeric identification code 12 . For an alphanumeric identifier, it is understood as a series of letters and / or numbers and / or symbols. In the embodiment shown in the figures, said identification code 12 consists of the number "1" and the letter "A". The use of several numbers and / or numbers and / or symbols ...

Abstract

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).

Description

technical field [0001] The invention relates to a process capable of performing X-ray negative film detection on weld seams of pipeline systems. [0002] The technical field that the present invention relates to is a technology capable of correlating X-ray negative films with weld seams of pipes, plates or other items in a definite manner, and eliminating the possibility of counterfeiting. Background technique [0003] Usually, when the X-ray film is taken, the weld seam to be inspected by X-ray is marked by the filming operator (ie, marked when the X-ray film is taken). The operator is responsible for setting the number or printed letter; said number or letter can identify the weld to be X-ray inspection. Therefore, there may be a case where an operator maliciously modifies the seam identification information. For example, an operator can mark a weld he knows to be a bad weld as the x-ray number of a good weld. [0004] In order to overcome this shortcoming, patent docum...
