Welding and allied processes - Symbolic representation on drawings - Welded joints (ISO 2553:2013)

ISO 2553:2013 defines the rules to be applied for symbolic representation of welded joints on technical drawings. This may include information about the geometry, manufacture, quality and testing of the welds. The principles of this standard may also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In ISO 2553:2013: sections, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; sections, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; sections, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.
The symbols shown may be combined with other symbols used on technical drawings, for example to show surface finish requirements.
An alternative designation method is presented which may be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements.

Schweißen und verwandte Prozesse - Symbolische Darstellung in Zeichnungen - Schweißverbindungen (ISO 2553:2013)

Diese Internationale Norm legt Regeln fest, die in technischen Zeichnungen für die symbolische Darstellung von Schweißnähten anzuwenden sind. Die Symbole können Angaben zur Geometrie, Herstellung, Qualität und Prüfung der Schweißnähte enthalten. Die Grundsätze dieser Norm können auch für gelötete Verbindungen verwendet werden.
Es wird die Tatsache berücksichtigt, dass es auf dem Weltmarkt zwei unterschiedliche Methoden gibt, um in Zeichnungen die Pfeilseite und die Gegenseite zu kennzeichnen. Es sollte beachtet werden, dass in dieser Norm:
- Abschnitte, Tabellen und Bilder mit dem Suffix "A" nur für das System zutreffen, bei dem in den Symbolen eine doppelte Bezugslinie verwendet wird;
- Abschnitte, Tabellen und Bilder mit dem Suffix "B" nur für das System zutreffen, bei dem in den Symbolen eine einzelne Bezugslinie verwendet wird;
- Abschnitte, Tabellen und Bilder, in denen weder der Suffix "A" noch der Suffix "B" angegeben ist, für beide Darstellungssysteme zutreffen.
Die in dieser Internationalen Norm angegebenen Symbole dürfen mit anderen Symbolen kombiniert werden, die in technischen Zeichnungen angewendet werden, z. B. um Anforderungen an die Oberflächen-beschaffenheit darzustellen.
Ein alternatives Bezeichnungsverfahren wird beschrieben, das angewendet werden darf, um in Zeichnungen die wichtigsten Konstruktionsangaben für Schweißverbindungen festzulegen, z. B. Nahtmaße, Bewertungs-gruppen usw. Die Schweißnahtvorbereitung und der/die Schweißprozess(e) werden anschließend von dem Hersteller so festgelegt, dass die spezifischen Anforderungen erfüllt werden.
ANMERKUNG Die in dieser Internationalen Norm angegebenen Beispiele, einschließlich der Maße, dienen nur zur Veranschaulichung der korrekten Anwendung der Prinzipien. Die Beispiele sind nicht repräsentativ für bewährte Konstruktionspraktiken und nicht dazu vorgesehen, die Anforderungen aus Vorschriften oder Spezifikationen zu ersetzen.

Soudage et techniques connexes - Représentations symboliques sur les dessins - Joints soudés (ISO 2553:2013)

L'ISO 2553:2013 définit les règles à suivre pour représenter symboliquement les joints soudés sur les dessins techniques. Cela peut inclure des informations sur la géométrie, la fabrication, la qualité et les essais des soudures. Les principes de la présente Norme internationale peuvent également être appliqués aux joints soudés et brasés.
L'ISO 2553:2013 reconnaît qu'il existe deux méthodes différentes sur le marché mondial pour désigner le côté ligne repère et le côté opposé à la ligne repère sur les dessins. Il convient de noter que les articles, tableaux et figures qui portent le suffixe «A» sont applicables uniquement au système de représentation symbolique fondé sur un double trait de référence; les articles, tableaux et figures qui portent le suffixe «B» sont applicables uniquement au système de représentation symbolique fondé sur un trait de référence simple; les articles, tableaux et figures qui ne portent ni le suffixe «A» ni le suffixe «B» sont applicables aux deux systèmes.
Les symboles donnés dans la présente Norme internationale peuvent être combinés à d'autres symboles utilisés sur les dessins techniques, par exemple pour indiquer les exigences de finition de surface.
Une autre méthode de désignation est donnée. Elle peut être utilisée pour représenter des joints soudés sur les dessins en spécifiant les informations essentielles de conception, tels que les dimensions de la soudure, le niveau de qualité, etc. La préparation du joint et le(s) procédé(s) de soudage sont ensuite déterminés par l'unité de production afin de satisfaire aux exigences spécifiées.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
