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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
Requests for official interpretations of any aspect of this International Standard should be directed to
the Secretariat of ISO/TC 44/SC 3 via your national standards body. A complete listing of these bodies
can be found at www.iso.org.
This third edition cancels and replaces the second edition (ISO 14172:2008), which has been

INTERNATIONAL STANDARD ISO 14172:2015(E)
Welding consumables — Covered electrodes for
manual metal arc welding of nickel and nickel alloys —
Classification
1 Scope
This International Standard prescribes requirements for the classification of nickel and nickel-alloy
covered electrodes for manual metal arc welding and overlaying. It includes those compositions in
which the nickel content exceeds that of any other element.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 544, Welding consumables — Technical delivery conditions for filler materials and fluxes — Type of
product, dimensions, tolerances and markings
ISO 6847, Welding consumables — Deposition of a weld metal pad for chemical analysis
ISO 14344, Welding consumables — Procurement of filler materials and fluxes
ISO 15792-1:2000, Welding consumables — Test methods — Part 1: Test methods for all-weld metal test
specimens in steel, nickel and nickel alloys. Amended by ISO 15792-1:2000/Amd 1:2011.
ISO 80000-1:2009, Quantities and units — Part 1: General
3 Classification
A covered electrode shall be classified in accordance with the chemical composition of the all-weld metal
as given in Table 1 and the mechanical properties listed in Table 2. The symbol for the classification is
divided into two parts:
a) the first part gives a symbol indicating the product/process to be used;
b) the second part gives a symbol indicating the chemical composition of the all-weld metal.
4 Symbols and requirements
4.1 Symbol for the product/process
The symbol for covered electrodes used for manual metal arc welding shall be the letter “E”.
ISO 14172:2015(E)
4.2 Symbol for the chemical composition of the all-weld metal
The symbol for the chemical composition of the all-weld metal shall comprise “Ni” plus four digits, as
shown in Table 1. The first digit is an indicator of the class of alloy deposited, where
2 indicates no significant alloy addition,
4 indicates significant copper addition (nickel-copper alloys),
6 indicates significant chromium addition, with iron less than 25 % (nickel-chromium-iron and
nickel-chromium-molybdenum alloys),
8 indicates significant chromium addition, with iron more than 25 % (nickel
