    [0001] - 1 - METHOD FOR CONTROLLING WELDING BY RADIOGRAPHY Description Technical field of the invention.
    [0002] The invention relates to a method for controlling a radiographic image of a pipe weld. It relates to the technical field of techniques for associating in a certain way, without the possibility of falsification, a radiograph to a welding pipe, plate, or any other object. State of the art
    [0003] The location of the X-ray welds is usually done by a radio operator when the radio is fired (ie at the time of the X-ray image). It is this same operator who installs lead numbers or letters to identify the weld to be radiographed. It is therefore possible that a malicious operator could change the identification of the weld. For example, the operator can assign the number of a weld that he knows does not conform to the radiograph of a compliant weld. To overcome this, patent document EP2591447 (BEWEIS) describes a device for connecting a weld to be radiographed radiographically, without the possibility of falsification. This device consists of a support plate incorporating an alpha numerical identifier opaque to X and gamma rays. An opaque resin is poured into the shell of the support plate so that the identifier is invisible to the naked eye. This device further comprises a detachable sticker on which is registered the same alphanumeric identifier.
    [0004] The support plate is first attached to the pipework at the level of the weld to be controlled by a third person other than the radio operator. This third party will also have taken care to detach the sticker to paste it next to an identifier of the weld, for example in a list of weld IDs which are associated with numerical alpha identifiers.
    [0005] The radio operator makes the radio shot of the weld on which the support plate is arranged. The identifier appears on the X-ray. It is therefore only when the radio operator develops the X-ray that he knows the identifier written in the support plate. The link between the weld and the radiograph can then be done by reading the ID number on the plate and comparing it to the identifier on the sticker pasted into the list. In practice, an installation includes a large number of welds to control. In fact, the list of weld IDs associated with the numeric alpha identifiers includes a large number of references.
    [0006] The association, a posteriori, of a radiograph with the identifier of a weld is therefore generally tedious and time-consuming. The invention aims to remedy this state of affairs. In particular, an object of the invention is to simplify the association of a radiographic image with a welding identifier, while continuing to guard against any falsification. Another object of the invention is to control more quickly a radiographic image of a weld.
    [0007] A subsidiary objective of the invention is to automate as much as possible the control of a radiographic image of a weld.
    [0008] Disclosure of the invention.
    [0009] The solution proposed by the invention is a method for controlling an X-ray weld. This method is remarkable in that it comprises the following steps: - associate a unique identifier to the weld to be controlled, - write on a label an alpha numeric identifier and the unique identifier of the weld, at least the alpha identifier digital being visibly inscribed with the naked eye, - integrating in a support plate the same alpha numerical identifier as that inscribed on the label, which identifier is invisible to the naked eye and composed of X-ray opaque elements and gamma, - install the support plate at the weld and take a x-ray of the solder / support plate assembly, - fix the label on the x-ray taken, - develop the x-ray taken, so that the alpha-numeric identifier becomes visible to the naked eye on said snapshot, - check the correspondence between the alpha numerical identifier visible to the naked eye on the x-ray developed and the alpha numeric identifier written on the label. Thanks to this method, it is now possible to easily and quickly check the combination of a radiograph with a solder ID. Indeed, by affixing the label on the X-ray, the person who holds the X-ray developed can instantly check the correspondence between the alpha numeric identifier that appears on this plate and the alpha numeric identifier on the label. This method also ensures optimum security, since neither the label nor the support plate can be falsified.
    [0010] Other advantageous features of the method which is the subject of the invention are listed below. Each of these characteristics can be considered alone or in combination with the remarkable features defined above, which remarkable features are not necessarily indispensable as such for the resolution of technical problems that the following features propose to solve: - It is advantageously included in the support plate a first RFID chip and alpha numerical identifier opaque to X and gamma rays; and incrementing the memory of this first RFID chip with: the numerical alpha identifier, and the unique identifier of the weld. - One can read the first RFID chip and edit a first label on which are inscribed at least: the alpha numerical identifier and the unique identifier of the weld, which registration is performed by encrypting these identifiers in a barcode or in the memory of a second RFID chip provided with said first tag. - After installing the support plate at the weld and taking a radiograph of the solder / support plate assembly, the first label is glued on a sealed envelope in which the radiograph is inserted. Preferably, the bar code or the second RFID chip disposed on the first label affixed to the envelope is read, and the memory of a third RFID chip is incremented with: the numerical alpha identifier, and the unique identifier of the welding; a second label is then issued in which the third RFID chip is integrated, and this second label is inscribed, visibly to the naked eye, at least the alpha numerical identifier and the unique identifier of the weld; after having taken the radiographic image of the envelope, the second label is glued on said plate; then the X-ray is developed so that the alpha numerical identifier is visible to the naked eye on said shot; we can then check the correspondence between the alpha numerical identifier which is visible to the naked eye on the developed snapshot and the numerical alpha identifier inscribed on the second label. - In case of correspondence between the alpha numerical identifier visible to the naked eye on the radiograph developed and the numerical alpha identifier on the second label: reads the third RFID chip, and generates a pre-filled report in which are recorded the information contained in the memory of the third RFID chip. - It is advantageously installed the support plate at the weld, attaching it to the pipe by means of a collar provided with a secure lock preventing the detachment of said collar. - One can also install the first label in a pouch, and hang this pouch on the collar to which is attached the support plate. the weld to be controlled can be geo-localized by integrating into the support plate geo-location information associated with the weld, and / or by associating the weld with geolocation information at the time of its production and / or by reading the first RFID chip by means of an RFID chip reader integrating a GPS module able to record GPS coordinates, and by recording in a memory of this reader, the GPS coordinates recorded at the time of reading said first chip.
    [0011] Another aspect of the invention relates to a system for controlling an X-ray weld. This system is remarkable in that it comprises: - a label on which is inscribed visibly with the naked eye: a unique identifier associated with the weld to be controlled and a numerical alpha identifier, - a support plate incorporating the same an alpha-numeric identifier that is inscribed on the label, which identifier is invisible to the naked eye and composed of elements that are opaque to X-rays and gamma rays, - an apparatus for taking a radiographic image of the solder / support-plate assembly, a means for attaching the tag to the radiograph taken, a means for developing the radiograph taken, so that the alpha numerical identifier becomes visible to the naked eye on said photograph; a means for verifying the correspondence between the digital alpha identifier visible to the naked eye on the developed radiograph and the digital alpha identifier written on the label. Other advantageous features of the system which is the subject of the invention are listed below. Each of these characteristics can be considered alone or in combination with the remarkable features defined above, which remarkable characteristics are not necessarily indispensable as such for the resolution of the technical problems that the following characteristics propose to solve: - The support plate is preferably attached to a pipe, at the weld, by means of a collar, said support plate being connected to said collar by means of a link configured to allow rotation of said support plate around of said piping. - The support plate may be formed of a shell having a housing in which are housed the constituent elements of the alpha numerical identifier, this housing being closed by an OPAQUE plate in which is integrated an RFID chip. Description of the figures.

    [0013] Preferred embodiments of the invention The following description refers to the control of a pipe weld. The invention is however applicable to the control of any other type of welding, for example a plate weld or any other object.
    [0014] Figure 1 illustrates various constituent elements of a support plate 1 according to the invention. It comprises a rigid or flexible shell 10, for example made by molding an opaque plastic. This shell is for example of rectangular shape, a length of about 5 cm, a width of about 4 cm, and a thickness of about 3 mm. The shell 10 has a housing 11 in which are housed the elements 120 constituting an alpha numerical identifier 12. By alpha numerical identifier is meant a series of letters and / or numbers and / or symbols.
    [0015] In the example illustrated in the appended figures, this identifier 12 consists of a number "1" and a letter "A". The use of several numbers and / or letters and / or symbols can of course be considered. The identifier 12 is unique and its constituent elements 120 are made of a material that is opaque to the radiation of the radio source, and more particularly to X and gamma rays. The elements 120 are preferably made of lead or brass. After having placed the elements 120 in the housing 11, and as shown in Figures 1 and 2, said housing is closed by a plate 13 in which is integrated an RFID chip 14. The latter is for example in the form of an electronic circuit glued or embedded in the plate 13, and comprising an antenna associated with an electronic chip for receiving and responding to radio requests transmitted from a transceiver reader. The plate 13 is opaque, for example made of rigid or flexible plastic. Its length and width correspond to those of the shell 1. Its thickness is however less, for example about 2 mm. The plate 13 can be glued or welded to the shell 1. Its attachment is such that its disassembly is impossible except to destroy the shell 1 and / or the RFID chip 14. A similar result is obtained by placing the RFID chip 14 in the housing 11, and casting in the latter an opaque resin. Once the support plate 1 is manufactured, the identifier 12 is invisible to the naked eye and it is no longer possible to disassemble it to falsify the elements 120. Referring to FIGS. 2 and 4, the plate support 1 is attached to the pipe T, at the weld S to be controlled. This operation is performed by an operator other than the radio operator. A collar 15, made of plastic or steel, is used, which is fastened around the tubing T. The collar 15 is provided with a secure lock 16 preventing its detachment from the tubing T.
    [0016] The support plate 1 is connected to the collar 15 by means of a link 17 in the form of a loop. In practice, the shell 10 of the support plate 1 comprises a bore 100 allowing the attachment of the link 17. The loop of the link 17 passes around the collar 15 so that the support plate 1 can freely rotate around the pipe. The radio operator thus has the possibility of moving the support plate 1 to position it at any level of the weld S, and more particularly according to the position envisaged for radio shooting.
    [0017] In practice, the radio operator positions the support plate 1 just next to the weld S, preferably adjacent, so that said support plate does not hide the image that will be taken of the weld. If several shots of the weld S must be taken at different angles, the radio operator can easily change the position of the support plate 1 accordingly.
    [0018] This type of support plate 1 is used to control radiographic radiographs of pipe welds. The plant to be tested is typically a plant or a nuclear power plant comprising several tens of linear meters of pipe on which several hundred welds are made. Each radiographic image is intended to highlight the internal structure of the weld S. In this photograph, the image of the identifier 12 integrated in the support plate 1 will be located next to the image of the internal structure of the weld S. welding S.
    [0019] Each weld S to be checked is associated with a unique identifier 20, preferably consisting of a series of letters and / or numbers and / or symbols. By way of example, and to illustrate the present invention, the identifier "C231A226" is associated with the weld S to be controlled. According to a preferred embodiment, the numerical alpha identifier 12 includes certain letters and / or numbers and / or symbols of the identifier 20 of the weld. Example: C231A226 1A. In order to facilitate the identification of a weld S in the installation, each weld is advantageously associated with geolocation information at the time of its production. For example, as soon as the welder has made the weld, he can record his position, and therefore that of the weld, by means of a touch-sensitive tablet, which tablet integrates a geolocation program making it possible for example to associate GPS coordinates to the identifier of the weld S. One can also read the first RFID chip 14 by means of an RFID chip reader integrating a GPS module able to record GPS coordinates. At the time of reading the first chip 14, the GPS coordinates recorded are stored in a memory of this reader. It is then possible to associate these GPS coordinates with the unique number of the chip 14 and incidentally with the identifier 20 of the weld S. During the manufacture of the support plate 1, the memory of the first RFID chip 14 is incremented. with the digital alphanumeric identifier 12, and with the unique identifier 20 of the weld S. This incrementation is performed automatically by means of software of the type known to those skilled in the art. It is also possible to integrate in the support plate 1, and more particularly in the memory of the first RFID chip 14, geo-location information associated with the weld 20 S. It may for example be the aforementioned GPS coordinates. In this way, by scanning the first RFID chip, an operator can control that he installs the support plate 1 at the corresponding weld S. Before installing the support plate 1, the first RFID chip 14 is read - or scanned - by means of a transceiver reader. This type of device makes it possible to exchange information with an RFID chip and is of the type known to those skilled in the art. This reader is coupled to a management unit, for example of the computer type, integrating a processor and a memory in which a computer program is recorded whose instructions, when they are executed by said processor, make it possible to automatically edit at least a first label 2 via a printer.
    [0020] The first label 2, shown schematically in FIG. 3, is for example a self-adhesive label. It includes among other things the inscription of the identifier "C231A226" of the weld S. This identifier 20 can be visible to the naked eye and / or be invisible by being encryptedly inscribed in a barcode (of which QR - Code) or in the memory of a second RFID chip 21 which is provided with the first label 2. The digital alpha identifier 12 "1A" can also be encrypted in a barcode or in the memory of the second RFID chip 21. The latter can furthermore include other inscriptions such as: name of the installation, name of the welder, location of the weld, material of the weld, etc. For optimal control of the S-weld, it is necessary to take several X-rays from several angles. In practice, it is expected to print several identical first labels 2 so that for a weld S, the radio operator can associate one of these labels to each x-ray taken. As it appears in FIG. 4, it appears advantageous to install these first labels 2 in a pouch 22, and to hang this pouch on the collar 15 to which the support plate 1 is attached.
    [0021] The radio operator installs the support plate 1 at the weld S (depending on the angle chosen) and takes a radiographic image of the solder / support plate assembly using a conventional radiographic apparatus. As illustrated in FIGS. 4 and 5, the radiographic image 3 is initially inserted into an envelope 4 making it possible to protect it from light. And the radio plug is done by maintaining the snapshot 3 inserted in its envelope 4 protection. It is only at the time of its development that the snapshot 3 will be out of the envelope 4.
    [0022] Referring to FIG. 5, as soon as the radiographic image 3 is taken, and before any development, the radio operator fixes a first label 2 on the sealed envelope 4, for example by means of glue previously disposed on a face of said label, or by any other similar fastening means. The radio operator repeats this operation for each shot taken from the weld S, and for each other weld of the installation.
    [0023] According to the example illustrated by the appended figures and more particularly by FIG. 6, at the end of its inspection, the radio operator has several envelopes 4 each containing a radiographic plate 3. The radio operator, or another operator reads the bar code or the second RFID chip 21 disposed on the first label 2. This reading is performed by means of a reader 40 adapted (type barcode reader, RFID chip scanner, ...) coupled to a unit The latter is for example in the form of a computer, incorporating a processor and a memory in which is recorded a computer program whose instructions, when executed by said processor, allow: extracting all or part of the data contained in the memory of the second RFID chip 21, and in particular the digital alpha identifier 12 and the unique identifier 20 of the solder S, and incrementing the memory a third RFID chip 51 with these identifiers 12 and 20. The electronic management unit 41 can also drive a printer 42 to automatically edit a second label 5 can directly integrate the third RFID chip 51. The latter can also be integrated into the label 5 after its edition, for example by gluing. At least the digital alpha identifier 12 is visibly inscribed on the second label 5. The unique identifier 20 of the weld S and / or other information can also be conspicuously inscribed on the 5 and / or invisibly in a barcode or in the memory of the third RFID chip 51. -13- After taking out the radiograph 3 of the envelope 4, the second label 5, in which is integrated the third RFID chip 51, is fixed on said plate, for example by means of glue previously disposed on one side of said label, or by any other similar fastening means.
    [0024] As illustrated in FIG. 7, the radiographic image 3 is then developed to reveal the latent image of the internal structure of the weld S and the latent image of the digital alpha identifier 12 which thus becomes visible to the naked eye. This development is done automatically or manually using a conventional processor. For example, it is possible to use a processor marketed by the company 3M® under the trademark DryView®. An operator then checks the correspondence between the digital alpha identifier 12 visible to the naked eye on the radiograph 3 developed and the numerical alpha identifier 12 inscribed on the second label 5. This verification is performed manually with the naked eye, or automatically by means of a scanner. If there is no correspondence between these two alphanumeric identifiers, a forgery must be indicated by any appropriate means. In case of correspondence, the operator can make a report.
    [0025] More particularly, by examining the image, a qualified operator interprets the image of the internal structure of the weld S by identifying the present indications and evaluating them according to the standards in force and / or according to particular specifications. The warned operator may, for example, detect the presence of defects such as microcracks or, on the contrary, ascertain the integrity of the weld S. This evaluation is then retranscribed in the operator's report. According to an advantageous characteristic of the invention illustrated in FIG. 7, the establishment of this report is automated at least in part. If there is a correspondence between the digital alpha identifier 12 visible to the naked eye on the plate 3 and the digital alpha identifier 12 written on the second label 5, the third RFID chip 51 is read by means of a reader 60 of the type described above. This reader 60 is coupled to an electronic management unit 61 which is for example in the form of a computer, integrating a processor and a memory in which is recorded a computer program whose instructions, when executed by said processor , allow to generate a pre-filled report 7 in which are recorded the information contained in the memory of the third RFID chip 51. This report 7 can be generated in paper form by means of a printer controlled by the unit 61, or in format electronic. In this report 7, the information contained in the memory of the third RFID chip 51 may be automatically recorded, and in particular: the identifier 20 of the weld S, the alphanumeric identifier 12, the date of taking the radiographic image, the information geo-location of the weld, the name of the operator who interpreted the radiograph 3, the name of the installation, the name of the welder, the material of the weld, etc. The operator can then manually enter observations concerning the internal structure of the weld such as: absence or presence of defects, location of these defects, recommended measures, etc. The arrangement of the various elements and / or means and / or steps of the invention, in the embodiments described above, should not be understood as requiring such an arrangement in all implementations. In any case, it will be understood that various modifications may be made to these elements and / or means and / or steps, without departing from the spirit and scope of the invention. In particular: the support plate 1 can be used independently of the various labels and / or RFID chips described above, and to control other objects than a pipe weld, the radio operator can directly paste the first label 2 on the radiograph 3 and not on the envelope 4.5
