Resistance welding - Procedure for spot welding of uncoated and coated low carbon steels (ISO 14373:2015)
ISO 14373:2015 specifies requirements for resistance spot welding in the fabrication of assemblies of uncoated and metallic coated low carbon steel, comprising two or three sheets of metal, where the maximum single sheet thickness of components to be welded is within the range 0,4 mm to 3 mm, for the following materials: uncoated steels; hot-dip zinc or iron-zinc alloy (galvannealed) coated steel; electrolytic zinc, zinc-iron, or zinc-nickel coated steel; aluminium coated steel; zinc-aluminium coated steel. It is applicable to welding of sheets of the same or dissimilar thickness, where the thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses, where the total thickness is less than or equal to 9 mm.
Welding with the following types of equipment is within its scope: pedestal welding equipment; gun welders; automatic welding equipment where the components are fed by robots or automatic feeding equipment; multi welders; robotic welders. It also gives information, for guidance only, on appropriate welding equipment on spot welding conditions.
The welding of organic coated or primer coated steels is not within its scope.
Widerstandsschweißen - Verfahren zum Punktschweißen von niedriglegierten Stählen mit oder ohne metallischem Überzug (ISO 14373:2015)
Diese Internationale Norm legt die Anforderungen an das Widerstandspunktschweißen an Bauteilen aus niedriglegiertem Stahl mit oder ohne metallischem Überzug fest, die aus zwei oder drei verschiedenen Blechdicken bestehen können, wobei die maximale Dicke eines Einzelbleches der zu schweißenden Bauteile im Bereich von 0,4 mm bis 3 mm aus folgenden Werkstoffen liegt:
- Stahl ohne Überzug;
- Stahl mit Feuerverzinkung oder Fe Zn Legierung (Galvannealed);
- Stahl mit elektrolytisch aufgebrachtem Zn oder Zn Ni Überzug;
- Stahl mit Aluminiumüberzug;
- Stahl mit Zn Al Legierungsüberzug.
Diese Internationale Norm gilt für das Schweißen von Blechen oder Platten gleicher oder unterschiedlicher Dicke mit einem Dickenverhältnis von nicht mehr als 3:1. Sie gilt auch für die Dreiblechschweißung mit einer Gesamtdicke von bis zu 9 mm.
Die folgenden Schweißeinrichtungen liegen im Anwendungsbereich dieser Internationalen Norm:
a) Ständerschweißmaschinen;
b) Schweißpistolen;
c) automatische Schweißeinrichtungen, bei denen die Bauteile durch Roboter oder automatische Zuführungen zugeführt werden;
d) Vielpunktschweißanlagen;
e) Roboterschweißanlagen.
Anhang A enthält Angaben über geeignete Schweißeinrichtungen und Anhang B informiert über die Punktschweißbedingungen. Diese Informationen dienen jedoch nur als Anhalt. In Abhängigkeit von den Fertigungsbedingungen, der Schweißeinrichtung, den Eigenschaften des Sekundärkreises, dem Elektrodenwerkstoff und der Elektrodengeometrie sind gegebenenfalls Anpassungen erforderlich. Falls eine entsprechende Anwendungsnorm hierzu existiert, können weiterführende Informationen daraus entnommen werden.
Das Schweißen von organisch oder mit Primern beschichteten Stählen liegt nicht im Anwendungsbereich dieser Internationalen Norm.
Soudage par résistance - Mode opératoire pour le soudage par points des aciers à bas carbone revêtus et non revêtus (ISO 14373:2015)
L'ISO 14373:2015 spécifie les exigences relatives au soudage par résistance par points pour la fabrication d'assemblages en acier à bas carbone revêtu ou non revêtu avec deux ou trois épaisseurs de métal, l'épaisseur maximale d'une tôle simple constituant les pièces à souder étant comprise entre 0,4 mm et 3 mm pour les matériaux suivants: aciers non revêtus; acier galvanisé à chaud ou revêtu d'un alliage de fer-zinc (recuit par galvanisation); acier avec revêtement électrolytique de zinc, zinc-fer ou zinc-nickel; acier revêtu d'aluminium; acier revêtu de zinc-aluminium. Elle s'applique au soudage de tôles présentant une épaisseur similaire ou différente, et dont le rapport entre les épaisseurs est inférieur ou égal à 3:1. Elle s'applique au soudage de trois épaisseurs, dont l'épaisseur totale est inférieure ou égale à 9 mm.
Elle concerne le soudage réalisé avec les types de matériels suivants: machine de soudage avec commande au pied; machines à souder mobiles (au pistolet); matériel de soudage automatique avec lequel les composants sont mis en place par des robots ou des appareils d'alimentation automatique; machines à souder multi-points; robots de soudage. Elle donne des informations sur le matériel de soudage approprié et sur les conditions de soudage par points. Ces renseignements ne sont fournis qu'à titre informatif.
Elle ne couvre pas le soudage d'aciers revêtus de produit organique ou d'apprêt (primaire).

Foreword
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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
