Welding consumables - Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels - Classification (ISO 636:2017)
ISO 636:2017 specifies requirements for classification of rods and wires in the as-welded condition and in the post-weld heat-treated condition for tungsten inert gas welding of non-alloy and fine-grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.
ISO 636:2017 is a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.
a) Paragraphs and tables which carry the suffix letter "A" are applicable only to rods and wires classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this document.
b) Paragraphs and tables which carry the suffix letter "B" are applicable only to rods and wires classified to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in accordance with this document.
c) Paragraphs and tables which have neither the suffix letter "A" nor the suffix letter "B" are applicable to all rods and wires classified in accordance with this document.

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 World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www . i so .org/ iso/ foreword .html.
The committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This fifth edition cancels and replaces the fourth edition (ISO 636:2015), of which it constitutes a minor
revision with the following changes:
— updates to the latest ISO style (including mandatory Clause 3 and subsequent renumbering of
clauses and subclauses);
— in Table 3B, the limits for Ti in the last column have been correctly assigned against NCCT1, NCCT2
and N1M2T and not against N9, NCC and NCC1 as in the 2015 edition;
— the newly agreed wording for Clause 8, “Rounding procedure”, has been introduced.
Requests for official interpretations of any aspect of this document 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

Introduction
This document provides a classification for the designation of rods and wires in terms of their chemical
composition and, where required, in terms of the yield strength, tensile strength, and elongation of
the all-weld metal. The ratio of yield to tensile strength of weld metal is generally higher than that of
parent metal. Matching weld metal yield strength to parent metal yield strength will not necessarily
ensure that the weld metal tensile strength matches that of the parent material. Where the application
requires matching tensile strengths, selection of consumables is made by reference to column 3 of
Table 1A or Table 1B.
Of note is that the mechanical properties of all-weld metal test specimens used to classify the rods and
wires vary from those obtained in production joints because of differences in welding procedure such
as diameter, width of weave, welding position, and material composition.
[1]
The classification according to system A is mainly based on EN 1668:1997 . The classification
according to system B is mainly based upon standards used around the Pacific Rim.
