Resistance welding - Procedure for spot welding of uncoated and coated low carbon steels (ISO 14373:2024)
This document specifies requirements for resistance spot welding in the fabrication of assemblies ofuncoated, and metallic coated or weldable non-metallic coated low carbon steel, comprising two orthree sheets of metal, where the maximum single sheet thickness of components to be welded is withinthe range 0,4 mm to 3 mm.
This document 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 the scope of this document:
a) pedestal welding equipment;
b) welding guns;
c) automatic welding equipment where the components are fed by robots or automatic feeding equipment;
d) multi welders;
e) robotic welders.
Information on appropriate welding equipment is given in Annex A, and information on spot welding conditions is given in Annex B. This information is provided for guidance only.Depending on the service conditions of the fabrication, the type of welding equipment, the characteristics of the secondary circuit, the electrode material, and the shape, it is possible that certain modifications are necessary. In such cases, further information can be obtained from the relevant application standard, where one exists.

Uporovno varjenje - Postopek točkovnega varjenja neprevlečenih in prevlečenih maloogljičnih jekel (ISO 14373:2024)
Ta dokument določa zahteve za uporovno točkovno varjenje pri izdelavi sklopov neprevlečenega jekla in varivega nizkoogljičnega jekla s kovinsko ali nekovinsko prevleko, sestavljenega iz dveh ali treh kovinskih plošč, pri čemer je največja debelina posamezne plošče komponent, ki so predvidene za varjenje, v razponu od 0,4 mm do 3 mm.
Ta dokument se uporablja za varjenje plošč z enako ali različno debelino in razmerjem debeline, manjšim ali enakim 3:1. Uporablja se za varjenje treh debelin, pri čemer je skupna debelina manjša ali enaka 9 mm. Na področje uporabe tega dokumenta spada varjenje z naslednjimi vrstami opreme:
a) oprema za varjenje s podstavkom;
b) varilne pištole;
c) oprema za avtomatsko varjenje (komponente dovajajo roboti ali oprema za avtomatsko dovajanje);
d) varilni aparati za različne vrste varjenja;
e) robotski varilni aparati.
Informacije o ustrezni opremi za varjenje so podane v dodatku A, informacije o pogojih točkovnega varjenja pa v dodatku B. Te informacije so podane zgolj kot smernice. Glede na delovne pogoje izdelave, vrsto opreme za varjenje, značilnosti sekundarnega tokokroga, material elektrod in obliko bodo morda potrebne določene spremembe. V takšnih primerih je mogoče dodatne informacije pridobiti v ustreznem standardu za uporabo, če ta obstaja.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
