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).

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 compliance with this document may involve the use of a patent.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that they are willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In
this respect, the statement of the holder of this patent right is registered with ISO. Information may be
obtained from the patent database available at www.iso.org/patents.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those in the patent database. ISO shall not be held responsible for identifying
any or all such patent rights.

Welding consumables — Solid wire electrodes, solid strip
electrodes, solid wires and solid rods for fusion welding of
nickel and nickel alloys — Classification
1 S cope
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.

4 Classification
The symbol for the classification is divided into two parts:
a) the first part indicates the product form, being solid wire electrode, solid strip electrode, solid wire
or solid rod, see 5.1;
b) the second part gives a numerical symbol indicating the chemical composition of the solid wire
electrode, solid strip electrode, solid wire or solid rod, see Table 1.
5 S ymbols and requirements
5.1 S ymbols for the product form
The symbol for the solid wire electrode, solid wire or solid rod shall be “S”.

---------------------- Page: 13 ----------------------
SIST EN ISO 18274:2023
ISO 18274:2023(E)
The symbol for the solid strip electrode shall be “B”.
NOTE One product form can be used for more than one welding process.
5.2 S ymbol for the chemical composition
The initial symbol “Ni” in Table 1 identifies the welding consumable as a nickel base alloy. The following
four digits indicate the chemical composition of the solid wire electrode, solid strip electrode, solid
wire or solid rod, determined under conditions given in Clause 6. The first digit is an indicator of the
alloy group as follows:
— 1, significant molybdenum addition without significant chromium addition (nickel-molybdenum
alloys);
— 2, no significant alloy addition;
— 4, significant copper addition (nickel-copper alloys);
— 5, significant copper additions with aluminium and titanium for precipitation hardening;
— 6, significant chromium addition, with iron less than 25 % (mass fraction) (nickel-chromium-iron
and nickel-chromium-molybdenum alloys);
— 7, same as 6, but with aluminium and titanium for precipitation hardening;
— 8, significant chromium addition, with iron more than 25 % (mass fraction) (nickel-iron-chromium
alloys);
— 9, an alloy that is precipitation hardenable.
The remaining digits indicate the alloy composition of the welding consumable. The basis of the system
of designation is described in Annex A. A description of common uses of each welding consumable alloy
is given in Annex B.
NOTE 1 In addition, the chemical symbol can be used.
NOTE 2 Corresponding national classifications are shown in Annex C, Table C.1.

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

Introduction
For nickel welding consumables, there is no unique relationship between the product form (solid wire
electrode, solid strip electrode, solid wire, solid rod) and the welding process used (e.g. gas shielded
metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, strip overlay
welding, laser welding or other welding processes). For this reason, the solid wire electrode, solid strip
electrode, solid wire, solid rod may be classified on the basis of any of the above product forms and can
be used as appropriate, for more than one of the above processes (see also Annex B).

DRAFT INTERNATIONAL STANDARD ISO/DIS 18274:2021(E)
Welding consumables — Solid wire electrodes, solid strip
electrodes, solid wires and solid rods for fusion welding of
nickel and nickel alloys — Classification
1 Scope
This document specifies requirements for classification of solid wire electrodes, solid strip electrodes,
solid wires, 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.
The principles of this standard can be applied to metal powders for cladding, hard facing and additive
manufacturing.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
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.
ISO 544, Welding consumables — Technical delivery conditions for filler materials and fluxes — Type of
product, dimensions, tolerances and markings
ISO 14344, Welding consumables — Procurement of filler materials and fluxes
ISO 80000-1:2009, Quantities and units — Part 1: General
3 Terms and definitions
No terms and definitions are listed in this document.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at https:// www .electropedia .org/
4 Classification
The classification is divided into two parts:
a) the first part indicates the product form, being solid wire electrode, solid strip electrode, solid
wire, solid rod, see 5.1;
b) the second part gives a numerical symbol indicating the chemical composition of the solid wire
electrode, solid strip electrode, solid wire, solid rod, see Table 1.
5 Symbols and requirements
5.1 Symbols for the product form
The symbol for the solid wire electrode, solid wire or solid rod shall be “S”.
© ISO 2021 – All rights reserved 1
---------------------- Page: 9 ----------------------
oSIST prEN ISO 18274:2021
ISO/DIS 18274:2021(E)
The symbol for the solid strip electrode shall be “B”.
NOTE One product form can be used for more than one welding process.
5.2 Symbol for the chemical composition
The initial symbol “Ni” in Table 1 identifies the welding consumable as a nickel base alloy. The following
four digits indicate the chemical composition of the solid wire electrode, solid strip electrode, solid
wire or solid rod, determined under conditions given in Clause 7. The first digit is an indicator of the
alloy group as follows:
— 1, significant molybdenum addition without significant chromium addition (nickel-molybdenum
alloys);
— 2, no significant alloy addition;
— 4, significant copper addition (nickel-copper alloys);
— 5, significant copper additions with aluminium and titanium for precipitation hardening;
— 6, significant chromium addition, with iron less than 25 % (by mass) (nickel-chromium-iron and
nickel-chromium-molybdenum alloys);
— 7, same as 6, but with aluminium and titanium for precipitation hardening;
— 8, significant chromium addition, with iron more than 25 % (by mass) (nickel-iron-chromium
alloys).
The remaining digits indicate the alloy composition of the welding consumable. A description of common
uses of each welding consumable alloy is given in Annex A. The basis of the system of designation is
described in Annex B.
NOTE 1 In addition, the chemical symbol can be used.
NOTE 2 Corresponding national classifications are shown in Annex C

6 Mechanical properties of the weld metal
Mechanical properties of the weld metal are not part of the classification.
NOTE Information on typical weld metal tensile strengths, where they exist, can be found in Annex C.
7 Chemical analysis
Chemical analysis shall be performed on specimens of the product or the stock from which it is made.
Any analytical technique can be used, but in case of dispute, reference shall be made to established
published methods, agreed between the contracting parties.
NOTE 1 The shielding gas or flux can influence the chemical composition of the all-weld metal as compared to
the chemical analysis of the product or stock.
NOTE 2 See Annex B.
8 Rounding procedure
Actual test values obtained shall be subject to ISO 80000-1:2009, B.3, Rule A. If the measured values are
obtained by equipment calibrated in units other than those of this document, the measured values shall
be converted to the units of this document before rounding. If an average value is to be compared to the
requirements of this document, rounding shall be done only after calculating the average. The rounded
results shall fulfil the requirements of the appropriate table for the classification under test.
9 Retests
If any test fails to meet the requirement(s), that test shall be repeated twice. The results of both retests
shall meet the requirement. Specimens for the retest may be taken from the sample or from one or two
new samples. For chemical analysis, retests need only be for those specific elements that failed to meet
the requirement. If the results of one or both retests fail to meet the requirement, the material under
test shall be considered as not meeting the requirements of this document for that classification.
In the event that during preparation, or after completion of any test, it is clearly determined that
prescribed or proper procedures were not followed in preparing the sample(s) or test specimen(s), or
in conducting the tests, the test shall be considered invalid. This determination is made without regard
to whether the test was actually completed, or whether the test results met, or failed to meet, the
requirements. That test shall be repeated, following proper prescribed procedures. In this case, the
requirement for doubling the number of test specimens does not apply.
10 Technical delivery conditions
Technical delivery conditions shall meet the requirements of ISO 544 and ISO 14344.
11 Designation
The designation of solid wire electrodes, solid strip electrodes, solid wires and solid rods shall follow
the principle given in the examples below.
EXAMPLE 1 A solid wire (S) for gas shielded metal arc welding having a chemical composition within the
limits for the alloy symbol 6625 (NiCr22Mo9Nb) of Table 1 is designated:
