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 s ubject 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 t he work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the m ember bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 12153 was prepared by Technical Committee 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

INTERNATIONAL STANDARD ISO 12153:2011(E)

Welding consumables — Tubular cored electrodes for gas
shielded and non-gas shielded metal arc welding of nickel and
nickel alloys — Classification
1 Scope
This International Standard specifies requirements for the classification of tubular cored electrodes for metal
arc welding with or without a gas shield of nickel and nickel alloys. It includes those compositions in which the
nickel content exceeds that of any other element.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the r eferenced
document (including any amendments) applies.

3 Classification
A tubular cored electrode shall be classified according to the chemical composition of the all-weld metal as
given in Table 1 and the mechanical properties of the all-weld metal listed in Table 2.
The classification designation is divided into five parts:
a) the first part gives a symbol indicating the product/process to be identified;
b) the second part gives a symbol indicating the chemical composition of the all-weld metal;
c) the third part gives a symbol indicating the type of electrode core;
d) the fourth part gives a symbol indicating the type of shielding gas;
e) the fifth part gives a symbol indicating the welding position.
ISO 12153:2011(E)
4 Symbols and requirements
4.1 Symbol for the product/process
The symbol for the tubular cored electrode used in the metal arc welding process shall be the letter “T”.
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 digits are an indicator of the class of alloy deposited, as follows:
⎯ 4 indicates significant copper addition (nickel-copper alloys)
⎯ 6 indicates significant chromium addition, with iron less than 25 % (by mass) (nickel-chromium-iron and
nickel-chromium-molybdenum alloys)
⎯ 10 indicates significant molybdenum addition without significant chromium addition (nickel-molybdenum
alloys)
The remaining digits indicate the particular alloy deposited.
The tubular cored electrode classified in accordance with Table 1 and produced as described in Clause 5 and
Clause 6 shall also fulfil the requirements of Table 2.
NOTE In addition, the chemical symbol can be used.
4.3 Symbol for the type of electrode core
The third part of the designation indicates the type of electrode core and the slag characteristics (see Table 3).
4.4 Symbol for the shielding gas
The symbols for shielding gases shall be in accordance with ISO 14175 except that the s ymbol NO shall be
used for tubular cored electrodes without a gas shield.
4.5 Symbol for the welding position
The fifth part of the designation (see Table 4) describes the welding position in which the tubular cored
electrode can be welded. PA, PB, PC, PD, PE, PF, and PG are the symbols of the welding positions in
accordance with ISO 6947:2011.
5 Chemical analysis
Chemical analysis shall be performed on any suitable all-weld metal test specimen. In case of dispute, the test
specimen specified in ISO 6847 shall be used. The test results shall meet the requirements of Table 1 for the
classification under test. Any analytical technique may be used, but in cases of dispute, reference shall be
made to established published methods.
