Non-destructive examination of welds - Ultrasonic examination of welded joints
This European Standard specifies methods for the manual ultrasonic examination of fusion welded joints in metallic materials equal to and above 8 mm thick which exhibit low ultrasonic attenuation (especially that due to scatter). It is primarily intended for use on full penetration welded joints where both the welded and parent material are ferritic. Where specified and appropriate, techniques may also be used : - on materials other than those stated ; - on partial penetration welds ; - with automated equipment by agreement between the contracting parties. Where material dependent ultrasonic values are specified in this standard they are based on steels having an ultrasonic sound velocity of 5920 ñ 50 m/s for longitudinal waves, and 3255 ñ 30 m/s for transverse waves. This is to be taken into account when examining materials with a different velocity. The standard specifies four examination levels, each corresponding to a different probability of detection of imperfections. Guidance on the selection of examination levels A, B and C is given in annex A. The requirements of the fourth examination level, which is intended for special applications, are in accordance with the general requirements of this standard and as agreed between the contracting parties. This standard, by agreement between the contracting parties, permits assessment of indications, for acceptance purposes, by either of the following methods : 1) Evaluation based primarily on length and echo amplitude of the signal indication ; 2) Evaluation based on characterization and sizing of the indication by probe movement methods.

La norme prend également en compte la vitesse du son ultrasonore dans l'évaluation des matériaux, un détail crucial pour les industriels travaillant avec des matériaux présentant des caractéristiques différentes. Dans l'ensemble, la norme EN 1714:1997 se révèle être un document fondamental pour les professionnels impliqués dans l'examen ultrasonore des soudures, offrant des directives claires et une flexibilité d'application qui lui confère une grande valeur dans le domaine de l'inspection non destructrice.
The EN 1714:1997 standard on the non-destructive examination of welds through ultrasonic examination of welded joints provides comprehensive guidelines that are crucial for ensuring the integrity of welded joints in metallic materials. The standard explicitly targets fusion welded joints that are 8 mm thick or more, particularly those exhibiting low ultrasonic attenuation, which highlights its relevance in industrial applications where precision and reliability are paramount. One of the significant strengths of this standard is its clear definition of the scope, allowing for flexibility in its application. While primarily focused on full penetration welded joints made of ferritic materials, it also accommodates alternative materials, partial penetration welds, and utilization of automated equipment, underscoring its adaptability across various welding scenarios. This adaptability ensures that the standard remains pertinent in diverse industrial contexts. Moreover, the EN 1714 standard delineates four distinct examination levels that cater to different probabilities of detection of imperfections. This stratified approach allows operators and engineers to select appropriate examination levels based on specific requirements and the critical nature of the components being inspected. Annex A’s guidance on levels A, B, and C further enhances clarity and usability, facilitating informed decision-making in ultrasonic examinations. The standard's provision for the assessment of indications for acceptance purposes through two defined methods - evaluation based on length and echo amplitude or characterization and sizing by probe movement - is another notable strength. This flexibility in assessment techniques allows for tailored approaches depending on the unique needs of each project, making the standard highly relevant for modern non-destructive testing practices. In summary, EN 1714:1997 stands out as a robust framework for the ultrasonic examination of welded joints. Its thorough scope, coupled with its strengths in flexibility, stratification, and evaluation methods, reinforces its importance in ensuring the reliability and safety of welded constructions in various industries.

Die Norm EN 1714:1997 beschreibt die nicht-destructive Prüfung von Schweißnähten durch Ultraschalluntersuchungen an geschweißten Verbindungen in metallischen Materialien mit einer Dicke von 8 mm oder mehr, die eine geringe ultrasonische Dämpfung aufweisen. Diese europäische Norm richtet sich in erster Linie auf voll durchdringende Schweißverbindungen, bei denen sowohl das geschweißte Material als auch das Grundmaterial ferritisch sind. Die Stärke dieser Norm liegt in ihrer breiten Anwendbarkeit und der klaren Strukturierung der Prüfmethoden. Durch die Möglichkeit, auch auf Materialien, die nicht explizit in der Norm erwähnt sind, sowie auf Teilpenetrationsschweißnähten anzuwenden, wird ihre Flexibilität unterstrichen. Zudem können die Prüfmethoden im Einvernehmen der Vertragsparteien auch mit automatisierten Geräten durchgeführt werden, was den Einsatz in der modernen industriellen Fertigung erleichtert. Ein weiteres bemerkenswertes Merkmal dieser Norm ist die Angabe der vier Prüfungsstufen, die jeweils einer unterschiedlichen Wahrscheinlichkeit der Erkennung von Unvollkommenheiten entsprechen. Dies ermöglicht eine gezielte Auswahl der Prüfungsstufe, die den spezifischen Anforderungen des jeweiligen Projekts entspricht. Die Anhänge, insbesondere Anhang A, bieten zudem wertvolle Hinweise zur Auswahl der Prüfungsstufen A, B und C, was die Anwendung der Norm noch benutzerfreundlicher macht. Die Norm berücksichtigt auch die materialabhängigen Schallgeschwindigkeiten und verweist auf spezifische Werte, die bei der Prüfung von Materialien mit unterschiedlichen Geschwindigkeiten zu beachten sind. Dies gewährleistet, dass die Prüfmethoden unter Berücksichtigung der individuellen Materialeigenschaften zur zuverlässigen Erkennung von Imperfektionen eingesetzt werden. Ein Schlüsselpunkt ist die Zulässigkeit, wie Indikationen bewertet werden können, was den Vertragsparteien Flexibilität bei der Annahme von Ergebnissen gibt. Die zwei Methoden zur Bewertung von Indikationen – anhand von Länge und Echoamplitude oder durch Charakterisierung und Dimensionierung der Indikation – bieten eine differenzierte Herangehensweise, die an die spezifischen Prüfbedingungen angepasst werden kann. Insgesamt bietet die Norm EN 1714:1997 eine umfassende und praxisnahe Grundlage für die Ultraschallprüfung von Schweißnähten, die sowohl für Fabrikate in der Schweißtechnik als auch für die Qualitätskontrolle in der Herstellung von Bedeutung ist. Ihre Relevanz zeigt sich in der Gewährleistung von Qualität und Sicherheit in industriellen Anwendungen.
