Mit Hilfe der neuerungsgemäßen Vorrichtung ist eine genau definierte, den US-Anzeigen entsprechende Prüfung der Röntgenfilme möglich, da die Anzeigen durch das Aufleuchten des oder der Kontrollämpchen für jedes Teilfeld gekennzeichnet sind.With the help of the device according to the innovation, a precisely defined, X-ray films can be tested in accordance with the US displays, since the displays are activated by the or the control lights for each subfield are marked.

Die Neuerung betrifft eine Vorrichtung zur Röntgenfilmauswertung bei der Prüfung UP-geschweißter Rohre, insbesondere von längsnahtgeschweißten Großrohren.The innovation relates to a device for X-ray film evaluation when testing UP-welded pipes, in particular of longitudinally welded large pipes.
Bekannterweise werden von dem mit US-Anzeigen behafteten Anzeigenbereich bei der zerstörungsfreien Prüfung von Schweißnähten Röntgenfilme angefertigt. Bei der bisher üblichen Prüfung muß der gesamte auf dem Film wiedergegebene Bereich über ein Sichtgerät geprüft werden. Hierbei muß der Bedienungsmann den gesamten Sichtbereich des Gerätes mit gleicher Intensität überwachen, da eine gezielte Angabe fehlerverdächtigter Nahtstellen mit den bisher bekannten Geräten nicht möglich ist. Diese Prüfung kann durch die Monotonie der Überwachung zu Unsicherheiten bei der Filmauswertang führen.As is known, from the advertising area with US advertisements X-ray films made during the non-destructive testing of weld seams. With the usual one Test, the entire area reproduced on the film must be checked using a viewing device. The operator has to do this Monitor the entire field of vision of the device with the same intensity, as a specific indication of suspected errors Seams with the previously known devices is not possible. This test can get through the monotony the monitoring lead to uncertainties in the film evaluation.
Es ist Aufgabe der Neuerung, ein Gerät zur Röntgenfilmauswertung zu schaffen, das unter Ausnutzung bekannter Betriebsdaten-Erfassungssysteme (BDE-Systeme) eine Sichthilfe zur I Auswertung gibt, mit der die Überwachung auf geringstmögliche | Auswertebereiche eingeschränkt wird. |It is the task of the innovation to create a device for X-ray film evaluation which, using known operating data acquisition systems (BDE systems), provides a visual aid for I evaluation, with which the monitoring is as low as possible Evaluation areas is restricted. |

Die neuerungsgemäße Vorrichtung ermöglicht eine wesentlich
verbesserte Fehlerauffindung und Fehlerlokalisierung. Der
sogenannte Monotoneinfluß bei der bisherigen Überprüfung
der Röntgenfilme wird erheblich vermindert, so daß die Sicherheit und Genauigkeit der Überprüfung wesentlich gesteigert
werden kann.The device according to the innovation enables a substantial
improved error detection and localization. Of the
so-called monotonous influence in the previous review
the X-ray films is considerably reduced, so that the security and accuracy of the examination can be increased considerably.
In der beigefügten Zeichnung ist eine Ausführungsform der
neuerungsgemäßen Vorrichtung perspektivisch dargestellt.In the accompanying drawing is an embodiment of the
inventive device shown in perspective.
In der dargestellten Vorrichtung ist in einem Rahmen 1 ein
übliches Filmbetrachtungsfeld 2 eingesetzt. Dieses Betrachtungsfeld 2 ist am unteren Rand mit gleichmäßiger Unterteilung
3, z.B. im Abstand von 1 cm versehen. Jedes Teilfeld
3 ist mit einem zugehörigen Kontrollämpchen 4 ausgestattet. Zur Filmeinlage ist das Sichtgerät mit einer optischen Mittenpositionierung
5 versehen, die eine genaue Zuordnung der US-Anzeigen im Sichtbereich ermöglicht.In the device shown, a frame 1 is a
Usual film viewing field 2 used. This viewing field 2 is provided at the lower edge with a uniform subdivision 3, for example at a distance of 1 cm. Each subfield
3 is equipped with an associated control lamp 4. For the purpose of inserting a film, the viewing device is provided with an optical central positioning 5, which enables the US displays to be precisely assigned in the viewing area.
Das in d-«_r Beschreibungseinleitung erwähnte BDE-System (Betriebsdatenerfassungssystem) erfaßt alle Einzelinformationen aus dem Betrieb, auch die Prüfdaten der PrüfStationen.The BDE system (production data acquisition system) mentioned in the introduction to the description records all individual information from the company, including the test data from the test stations.
Bei der US-Prüfung werden alle US-Anzeigenstellen der Schweißnahtprüfung erfaßt und die zugehörigen Längenpositionen dem BDE-System übermittelt. Hieraus wird die Mittelposition der Röntgenfilme bestimmt.In the US test, all US display positions are used for the weld seam test recorded and the associated length positions transmitted to the PDA system. This becomes the middle position of X-ray films determined.
Bei der Röntgenprüfung erfolgt die Prüfung auch bezogen auf die gleichen Rohrlängenpositionen wie bei der US-Prüfung.In the case of the X-ray examination, the examination is also based on the same pipe length positions as in the US test.
Dabei wird während der Röntgenaufnahme jedem Film die vorher im BDE-Rechner ermittelte Filmmittenposition als Markierung mit Angabe der Längernposition dem Film aufbelichtet. DamitDuring the X-ray exposure, the center position of the film previously determined in the PDA computer is used as a marker for each film exposed to the film with an indication of the elongation position. In order to

erhält jeder Röntgenfilm eine vom BDE-System erfaßte Angabe, nämlich die errechnete Längenposition (Mittenposition).Each X-ray film receives an information recorded by the PDA system, namely the calculated length position (center position).
Bei der Auswertung gibt nun der Filmauswerter diese auf dem Film erkennbare Positionsnummer an das BDE-System weiter. Da im BDE-Rechner alle Positionen der US-Anzeigenstellen vorhanden sind, werden die zu dem auszuwertenden Film zugehörigen US-Anzeigen 6 an den Filmbetrachungskasten gemeldet. Die entsprechenden Lämpchen 4a, 4b leuchten dann auf.During the evaluation, the film evaluator forwards this position number, which can be seen on the film, to the BDE system. There If all positions of the US advertisements are available in the BDE computer, those associated with the film to be evaluated are displayed US advertisements 6 reported to the film viewing box. The corresponding lights 4a, 4b then light up.
