Non-destructive testing of welds - Ultrasonic testing - Use of automated phased array technology for thin-walled steel components (ISO 20601:2018)
This document specifies the application of phased array technology for the semi- or fully automated ultrasonic testing of fusion-welded joints in steel parts with thickness values between 3,2 mm and 8,0 mm. This meets the typical range of tube wall thickness values in boilers, which is an important application of this testing technology. The minimum and maximum value of the wall thickness range can be exceeded, when testing level "D" of this document is applied. This document applies to full penetration welded joints of simple geometry in plates, tubes, pipes, and vessels, where both the weld and parent material are low-alloy and/or fine grained steel.
NOTE "Semi-automated testing" encompasses a controlled movement of one or more probes on the surface of a component along a fixture (guidance strip, ruler, etc.), whereby the probe position is unambiguously measured with a position sensor. The probe is moved manually. "Fully automated testing" includes mechanized propulsion in addition.
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 provides guidance on the specific capabilities and limitations of phased array technology for the detection, location, sizing and characterization of discontinuities in fusion-welded joints. Ultrasonic phased array technology can be used as a stand-alone technique or in combination with other non-destructive testing (NDT) methods or techniques, during manufacturing and testing of new welds/repair welds (pre-service testing).
This document specifies two testing levels:
— level "C" for standard situations;
— level "D" for different situations/special applications.
This document describes assessment of discontinuities for acceptance purposes based on:
— height and length;
— amplitude (equivalent reflector size) and length;
— go/no-go decision.
This document does not include acceptance levels for discontinuities.
Zerstörungsfreie Prüfung von Schweißverbindungen - Ultraschallprüfung - Verwendung von automatisierter phasengesteuerter Array-Technologie für dünnwandige Bauteile aus Stahl (ISO 20601:2018)
Essais non destructifs des assemblages soudés - Contrôle par ultrasons - Utilisation de la technique multi-éléments automatisés pour les composants en acier à paroi mince (ISO 20601:2018)
Le présent document spécifie l'application de la technique multi-éléments pour le contrôle par ultrasons semi-automatisé ou entièrement automatisé des assemblages soudés par fusion de pièces en acier ayant des valeurs d'épaisseur comprises entre 3,2 mm et 8,0 mm. Cela correspond à la gamme type des valeurs d'épaisseur de paroi des tubes dans les chaudières, qui constituent une application importante de cette technique de contrôle. Les valeurs minimale et maximale de la gamme d'épaisseurs de paroi peuvent être dépassées lorsque le niveau de contrôle «D» du présent document est appliqué. Le présent document s'applique aux assemblages soudés à pleine pénétration de géométrie simple sur plaques, tubes, tuyaux et récipients dans lesquels le métal de base et le métal fondu sont tous les deux constitués d'acier faiblement allié et/ou à grains fins.
NOTE Un «contrôle semi-automatisé» inclut un déplacement contrôlé d'un ou plusieurs traducteurs sur la surface d'un composant le long d'un montage (bande de guidage, règle, etc.), au cours duquel la position du traducteur est mesurée sans ambiguïté par un capteur de position. Le traducteur est déplacé manuellement. Un «contrôle entièrement automatisé» inclut une propulsion mécanisée en complément.
Lorsque les paramètres ultrasonores dépendant du matériau sont spécifiés dans le présent document, ils sont basés sur les aciers dans lesquels la vitesse de propagation du son est égale à (5 920 ± 50) m/s pour les ondes longitudinales et (3 255 ± 30) m/s pour les ondes transversales. Il est nécessaire de prendre en compte cette condition lors du contrôle de matériaux ayant des vitesses de propagation différentes.
Le présent document fournit des lignes directrices sur les possibilités et les limitations spécifiques de la technique multi-éléments pour la détection, la localisation, le dimensionnement et la caractérisation des discontinuités dans les assemblages soudés par fusion. La technique multi-éléments par ultrasons peut être utilisée de manière autonome ou en combinaison avec d'autres méthodes ou techniques d'essai non-destructif (END), pendant la fabrication et le contrôle de nouvelles soudures/soudures de réparation (contrôle avant service).
Le présent document spécifie deux niveaux de contrôle:
— niveau «C» pour les situations normales;
— niveau «D» pour des situations différentes/des applications spéciales.
Le présent document décrit l'évaluation des discontinuités à des fins d'acceptation, en se basant sur:
— la hauteur et la longueur;
— l'amplitude (taille équivalente du réflecteur) et la longueur;
— une décision acceptation/rejet.
Le présent document ne comporte pas de niveaux d'acceptation pour les discontinuités.
Neporušitveno preskušanje zvarnih spojev - Ultrazvočno preskušanje - Uporaba avtomatske tehnike s faznim krmiljenjem za tankostenske sestavne dele iz jekla (ISO 20601:2018)
Ta dokument določa uporabo avtomatske tehnike s faznim krmiljenjem za polavtomatsko ali avtomatsko ultrazvočno preskušanje talilno zvarjenih zvarov v kovinskih delih z debelino od 3,2 mm do 8,0 mm. To ustreza običajnemu razponu vrednosti debeline sten cevi v kotlih, kar je pomembna uporaba te preskusne tehnologije. Najmanjšo in največjo vrednost razpona debeline stene je mogoče preseči, kadar se uporablja preskusna raven »D« tega dokumenta. Ta dokument se uporablja za zvarne spoje s popolno penetracijo pri preprostih geometrijskih oblikah v ploščah, ceveh in posodah, pri čemer sta zvarjeni in osnovni material malolegirana in/ali drobnozrnata jekla.
OPOMBA: »polavtomatsko preskušanje« zajema nadzorovano gibanje ene ali več preskuševalnih glav na površini komponente vzdolž veznega elementa (vodilni trak, ravnilo itd.), pri čemer je položaj preskuševalne glave nedvoumno izmerjen s senzorjem položaja. Preskuševalna glava se premika ročno. »Avtomatsko preskušanje« dodatno zajema mehanski pogon.
Kadar so v tem dokumentu določeni od materiala odvisni ultrazvočni parametri, temeljijo na jeklih s hitrostjo (5920 ± 50) m/s za longitudinalne valove in (3255 ± 30) m/s za transverzalne valove. To je treba upoštevati pri preskušanju materialov z različno hitrostjo.
Ta dokument podaja smernice o specifičnih zmogljivostih in omejitvah tehnike s faznim krmiljenjem za zaznavanje, ugotavljanje lokacije in velikosti ter karakterizacijo prekinjenosti talilno zvarjenih zvarov. Tehnologijo ultrazvočne tehnike s faznim krmiljenjem je mogoče uporabiti kot samostojno tehniko ali v kombinaciji z drugimi metodami ali tehnikami neporušitvenega preskušanja med proizvodnjo in preskušanjem novih zvarov/popravljenih zvarov (preskušanje pred uporabo).
Ta dokument določa dve ravni preskušanja:
– raven »C« za standardne situacije;
– raven »D« za različne situacije/posebne uporabe.
Ta dokument opisuje oceno nehomogenosti za namene sprejemanja na osnovi naslednjega:
– višina in dolžina;
– amplituda (ekvivalentna reflektorska velikost) in dolžina;
– odločitev o ustreznosti/neustreznosti.
Ta dokument ne vključuje ravni sprejemljivosti za nehomogenosti.
