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.

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 24034:2010), which has been technically
revised. The main changes compared to the previous edition are as follows:
— a number of alloys in Table 1 have been updated;
— a number of typographical errors in Table 1 and Table B.1 have been corrected;
— Clause 8 has been updated to reflect the current agreed wording;
— in Clause 11, the words “Solid wire” have been deleted from each example designation;
— the last sentence of the second paragraph of A.1 has been deleted to align with A.15;
— a number of dated references in Annex B and the bibliography have been updated.

Introduction
This document proposes a classification in order to designate solid wire electrodes, solid wires and
rods in terms of their chemical composition.
There is no unique relationship between the product form (solid wire electrodes, solid wires or rods)
and the welding process used (gas-shielded metal arc welding, tungsten inert gas arc welding, plasma
arc welding or laser beam welding). For this reason, solid wire electrodes, solid wires and rods can be
classified in terms of their chemical composition.
In this document, the symbol of the welding process is not used, because:
a) different joining processes are performed with the same chemical component consumable;
b) the producer is not able to determine the process symbol before shipping.
Also, it should be noted that the mechanical properties of all-weld metal test specimens or welded
joints produced by welding consumables can vary from those obtained in production joints because of
differences in welding procedure and the base-metal alloy. For this reason, the mechanical properties of
all-weld metal or weld
