The work of preparing International Standards is normally c
21、arried 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 wor
22、k. 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 Inter
23、national 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 th
24、e 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 14343 was jointly prepared by the International Institute of Welding (IIW), Commission II, Arc Welding and Filler Metals, and Technical Committee ISO/
25、TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables. IIW has been approved as an international standardizing body in the field of welding by the ISO Council. This second edition cancels and replaces the first edition (ISO 14343:2002), which has been technically revised. It al
26、so incorporates the Amendment ISO 14343:2002/Amd.1:2006. 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 http:/www.iso.org/.

28、approaches in the global market to classifying a given stainless steel welding consumable, and that either or both can be used to suit a particular market need. One is the nominal composition approach, which uses designators to indicate the principal alloying elements at their nominal levels, in a p
29、articular sequence, and which is sometimes followed by chemical element symbols to indicate compositional modifications to the original grade. The other is the alloy type approach, which uses tradition-based three- or four-digit designations for certain original grades, sometimes followed by one or
30、more chemical element symbols indicating compositional modifications of the original. In both approaches, classification is based upon the chemical composition of the product. In many cases, a given product can be classified using both approaches, because the composition ranges, although slightly di
31、fferent, overlap to a considerable extent between the two. Designation by either type of classification, or both where suitable, identifies a product as being classified according to this International Standard. Many, but not all, commercial products addressed by this International Standard can be c
32、lassified using both approaches, and suitable products can be so marked. Classification according to system A, by nominal composition, is based mainly on EN 1207211), while that of system B, by alloy type, is mainly based upon standards used around the Pacific Rim. For stainless steel welding consum
33、ables, there is no unique relationship between the product form (wire electrode, strip electrode, wire or rod) and the welding process used (gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding). For this reas
34、on, the wire electrodes, strip electrodes, wires or rods can 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. 1) This was replaced by “EN ISO 14343:2007” when CEN adopted the previous edition of this International

37、n 1 Scope This International Standard specifies requirements for classification of wire electrodes, strip electrodes, wires and rods for gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag welding and laser beam welding of stainless and he
38、at-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition. This International Standard is a combined specification providing for classification utilizing a system based upon nominal composition (system A), or utilizing a
39、 system based upon alloy type (system B). a) Paragraphs which carry the label “classification according to nominal composition” and the suffix letter “A”, or “ISO 14343-A”, are applicable only to products classified according to system A; b) Paragraphs which carry the label “classification according
40、 to alloy type” and the suffix letter “B”, or “ISO 14343-B”, are applicable only to products classified according to system B. c) Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both. 2 Normative references
