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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see
www.iso.org/iso/foreword.html.
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
Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance
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.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html. Official

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
