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.
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 member 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 636 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This third edition cancels and replaces the second edition (ISO 636:1989), which has been technically revised.

Introduction
This International Standard 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. Users should note that 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 consumable should be made by reference to
column 3 of Table 1A or Table 1B.
It should be noted 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.
The classification according to system A is mainly based on EN 1668:1997, Welding consumables — Rods,
wires and deposits for tungsten inert gas welding of non alloy and fine grain steels — Classification. The
classification according to system B is mainly based upon standards used around the Pacific Rim.
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 which can be found at
www.iso.org.

INTERNATIONAL STANDARD ISO 636:2004(E)
Welding consumables — Rods, wires and deposits for tungsten
inert gas welding of non-alloy and fine-grain steels —
Classification
1 Scope
This International Standard 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.
This International Standard 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.
1) 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 International Standard.
2) 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 International Standard.
3) 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 International Standard.

3 Classification
Classification designations are based upon two approaches to indicate the tensile properties and the impact
properties of the all-weld metal obtained with rods or wires. The two designation approaches include
additional designators for some other classification requirements, but not all, as will be clear from the following
sections. In most cases, a given commercial product can be classified to the classification requirements in
both systems. Then either or both classification designations can be used for the product.
Rods or wires shall be classified according to their chemical composition in accordance with Table 3A or
Table 3B.
3A Classification by yield strength and 3B Classification by tensile strength and
47 J impact energy 27 J impact energy
The classification is divided into four parts:
