Non-destructive testing of welds - Ultrasonic testing - Use of time-of-flight diffraction technique (TOFD) (ISO 10863:2020)
This document specifies the application of the time-of-flight diffraction (TOFD) technique to the semi- or fully automated ultrasonic testing of fusion-welded joints in metallic materials of minimum thickness 6 mm.
It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low-alloyed carbon steel. Where specified and appropriate, TOFD can also be used on other types of materials that exhibit low ultrasonic attenuation (especially that due to scatter).
Where material-dependent ultrasonic parameters are specified in this document, they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves and (3 255 ± 30) m/s for transverse waves. It is necessary to take this fact into account when testing materials with a different velocity.
This document makes reference to ISO 16828 and provides guidance on the specific capabilities and limitations of TOFD for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. TOFD can be used as a stand-alone method or in combination with other non-destructive testing (NDT) methods or techniques, for manufacturing inspection, and for in-service inspection.
This document specifies four testing levels (A, B, C, D) in accordance with ISO 17635 and corresponding to an increasing level of testing reliability. Guidance on the selection of testing levels is provided.
This document permits assessment of TOFD indications for acceptance purposes. This assessment is based on the evaluation of transmitted, reflected and diffracted ultrasonic signals within a generated TOFD image.
This document does not include acceptance levels for discontinuities.
Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung - Anwendung der Beugungslaufzeittechnik (TOFD) (ISO 10863:2020)
Dieses Dokument legt die Anwendung der Beugungslaufzeit Technik (TOFD, en: time-of-flight diffraction) bei der halb- oder vollauto¬matisierten Ultraschallprüfung von Schmelzschweißverbindungen in metallischen Werkstoffen mit einer Dicke von mindestens 6 mm fest.
Es gilt für durchgeschweißte Verbindungen mit einfacher Geometrie in Platten, Rohren und Behältern, bei denen sowohl der Werkstoff der Schweißnaht als auch der Grundwerkstoff niedrig legierter Kohlenstoffstahl ist. Sofern festgelegt und angemessen, kann die TOFD-Technik auch auf andere Werkstoffarten angewendet werden, die eine geringe Schallschwächung aufweisen (dies gilt insbesondere für die durch Streuung verursachte Schallschwächung).
Sofern in diesem Dokument werkstoffabhängige Ultraschallparameter festgelegt sind, beruhen diese auf Stählen mit einer Schallgeschwindigkeit von (5 920 ± 50) m/s für Longitudinalwellen und (3 255 ± 30) m/s für Transversalwellen. Dies ist bei der Prüfung von Werkstoffen mit anderer Schallgeschwindigkeit zu berücksichtigen.
Dieses Dokument nimmt Bezug auf ISO 16828 und liefert einen Leitfaden hinsichtlich der besonderen Fähigkeiten und Einschränkungen der TOFD-Technik beim Auffinden, der Ortung, dem Ausmessen und der Charakterisierung von Inhomogenitäten in Schmelzschweißverbindungen. Die TOFD-Technik kann selbständig oder in Verbindung mit weiteren Verfahren oder Techniken der zerstörungsfreien Prüfung (ZfP) sowohl für die Prüfung während der Herstellung als auch für die Prüfung während des Betriebs angewendet werden.
Dieses Dokument legt vier Prüfklassen (A, B, C, D) nach ISO 17635 fest, die einem zunehmenden Grad der Zuverlässigkeit der Prüfung entsprechen. Ein Leitfaden für die Auswahl der Prüfklassen wird bereitgestellt.
Dieses Dokument erlaubt die Beurteilung von TOFD-Anzeigen zur Bestimmung der Zulässigkeit. Diese Beurteilung beruht auf der Bewertung durchgelassener, reflektierter und gebeugter Ultraschallsignale in einem erzeugten TOFD-Bild.
Dieses Dokument enthält keine Zulässigkeitsgrenzen für Inhomogenitäten.
Essais non destructifs des assemblages soudés - Contrôle par ultrasons - Utilisation de la technique de diffraction des temps de vol (TOFD) (ISO 10863:2020)
Le présent document spécifie l'application de la technique de diffraction des temps de vol (méthode TOFD, time-of-flight diffraction) pour le contrôle par ultrasons semi-automatique ou entièrement automatique des assemblages soudés par fusion de matériaux métalliques d'épaisseur minimale de 6 mm.
Cette technique s'applique aux joints soudés à pleine pénétration de géométrie simple sur plaques, aux tubes et aux récipients, dans lesquels le métal de base et le métal fondu sont tous les deux constitués d'acier au carbone faiblement allié. Dans le cas où son utilisation est spécifiée et qu'elle s'avère appropriée, la méthode TOFD peut également être utilisée sur d'autres types de matériaux qui présentent une atténuation ultrasonore faible (spécialement celle due à la dispersion).
Lorsque les paramètres ultrasonores dépendant du matériau sont spécifiés dans le présent document, ils sont basés sur les aciers qui présentent une vitesse de propagation sonore de (5 920 ± 50) m/s pour les ondes longitudinales et de (3 255 ± 30) m/s pour les ondes transversales. Il est nécessaire de prendre cela en compte lors du contrôle de matériaux ayant des vitesses de propagation différentes.
Le présent document fait référence à l'ISO 16828 et fournit des lignes directrices sur les possibilités et les limitations spécifiques de la méthode TOFD pour la détection, la localisation, le dimensionnement et la caractérisation des discontinuités dans les joints soudés par fusion. La méthode TOFD peut être utilisée de manière autonome ou en combinaison avec d'autres méthodes ou techniques d'essais non destructifs (END), pour le contrôle de fabrication et pour le contrôle en cours de service.
Le présent document spécifie quatre niveaux d'examen (A, B, C, D) conformément à l'ISO 17635, correspondant à des niveaux croissants de fiabilité de contrôle. Des lignes directrices relatives au choix des niveaux d'examen sont données.
Le présent document permet l'évaluation des indications TOFD à des fins d'acceptation. Cette évaluation est basée sur l'appréciation des signaux ultrasonores transmis, réfléchis ou diffractés dans une image produite par la méthode TOFD.
Le présent document ne comporte pas de niveaux d'acceptation pour les discontinuités.
