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 this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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

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 fourth edition cancels and replaces the third edition (ISO 14172:2015), which has been technically
revised.
The main changes are as follows:
— updated to latest style including foreword;
— aligned with ISO 18274 where possible;
— updated references;
— rounding procedure is now Clause 8;
— revised the chemical compositions for a number of chemical compositions in Table 1;
— added new alloys in Table 1;
— updated corresponding entries in other parts of the document;
— new Example 2 added;
— added Chinese alloys to Table C.1

Welding consumables — Covered electrodes for
manual metal arc welding of nickel and nickel alloys —
Classification
1 Scope
This document prescribes requirements for the classification of nickel and nickel-alloy covered
electrodes for manual metal arc welding and overlaying. The classification of the covered electrodes is
based on the chemical composition of their deposited all-weld metal. It includes those compositions in
which the nickel content exceeds that of any other element.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
