Welding consumables - Solid wire electrodes, solid strip electrodes, solid wires and solid rods for fusion welding of nickel and nickel alloys - Classification (ISO 18274:2023)

This document specifies requirements for classification of solid wire electrodes, solid strip electrodes, solid wires and solid rods for fusion welding of nickel and nickel alloys. The classification of the solid wire electrodes, solid strip electrodes, solid wires and solid rods is based on their chemical composition. It includes those compositions in which the nickel content exceeds that of any other element.
The principles of this document can be applied to metal powders for cladding, hard facing and additive manufacturing.

Schweißzusätze - Massivdraht- und Massivbandelektroden, Massivdrähte und -stäbe zum Schmelzschweißen von Nickel und Nickellegierungen - Einteilung (ISO 18274:2023)

Dieses Dokument legt Anforderungen für die Einteilung von Massivdrahtelektroden, Massivbandelektroden, Massivdrähten und Massivstäben zum Schmelzschweißen von Nickel und Nickellegierungen fest. Die Einteilung der Massivdrahtelektroden, Massivbandelektroden, Massivdrähte und Massivstäbe erfolgt nach ihrer chemischen Zusammensetzung. Dazu gehören auch solche Zusammensetzungen, bei denen der Nickelgehalt höher ist als der eines anderen Elements.
Die Grundsätze dieses Dokuments können auf Metallpulver zum Beschichten, Auftragen und für die additive Fertigung angewendet werden.

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).

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,
Subcommittee SC 3, Welding consumables, in collaboration with the European Committee for

with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 18274:2010), which has been technically
revised.
The main changes are as follows:
— new restricted alloy symbols, commonly used in the USA, added to Table 1 and Table C.1;
— alloy symbols updated in Table 1 and Table C.1;
— a new EXAMPLE 4 added to Clause 11 for a Z classification.

Introduction
For nickel welding consumables, there is no unique relationship between the product form, for example:
— solid wire electrode;
— solid strip electrode;
— solid wire;
— solid rod;
and the welding process used, for example:
— gas-shielded metal arc welding;
— gas tungsten arc welding;
— plasma arc welding;
— submerged arc welding;
— strip overlay welding;
— laser welding;
— other welding processes.
Consequently, solid wire electrodes, solid strip electrodes, solid wires or solid rods can be classified
on the basis of any of these product forms and can be used, as appropriate, for more than one of these
processes (see also Annex B).
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed
that compli
