Welding consumables - Solid wire electrodes, tubular cored electrodes and electrode/flux combinations for submerged arc welding of non alloy and fine grain steels - Classification (ISO 14171:2010)
ISO 14171:2010 specifies requirements for the classification of electrode/flux combinations and weld metal in the as-welded condition and in the post-weld heat-treated condition for submerged arc 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. One flux can be classified with different solid wire electrodes and tubular cored electrodes. The solid wire electrode is also classified separately based on chemical composition.
ISO 14171:2010 is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy for weld metal of 47 J, or utilizing a system based upon the tensile strength and the average impact energy for weld metal of 27 J.

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 14171 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 3, Welding consumables.
This second edition cancels and replaces the first edition (ISO 14171:2002), which has been technically
revised.
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

Introduction
This International Standard recognizes that there are two somewhat different approaches in the global market
to classifying a given electrode/flux combination, and allows for either or both to be used, to suit a particular
market need. Application of either type of classification designation (or of both where suitable) identifies a
product as classified in accordance with this International Standard.
This International Standard provides a classification system for the designation of solid wire electrodes in
terms of their chemical composition, tubular cored electrodes in terms of the deposit composition obtained
with a particular submerged arc flux and, where required, electrode/flux combinations in terms of the yield
strength, tensile strength and elongation of the all-weld metal deposit. The ratio of yield to tensile strength of
weld metal is generally higher than that of parent material. Users should note that matching weld metal yield
strength to parent material yield strength does not necessarily ensure that the weld metal tensile strength
matches that of the parent material. Thus, where the application of the material requires matching tensile
strengths, selection of the consumable should be made by reference to column 3 of Table 1A or 1B, as
appropriate.
Although combinations of electrodes and fluxes supplied by individual companies may have the same
classification, the individual wire electrodes and fluxes from different companies are not interchangeable
unless verified in accordance with this International Standard.
The mechanical properties of all-weld metal test specimens used to classify the electrode/flux combinations
vary from those obtained i
