9、ved iii 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 w
10、hich 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
11、 matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are c
12、irculated 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 International Standard may be the subject of patent rights. ISO shall no
13、t be held responsible for identifying any or all such patent rights. International Standard ISO 14343 was prepared in collaboration with the International Institute of Welding which has been approved by the ISO Council as an international standardizing body in the field of welding.

15、ISO 14343:2002(E) iv ISO 2002 All rights reserved Introduction It is recognized that there are two somewhat different approaches in the global market to classifying a given stainless steel welding consumable, and that market allows for either or both to be used, to suit a particular market need. One
16、 is termed the “Nominal Composition” approach, which uses designators that indicate the principal alloying elements at their nominal levels, in a particular sequence, sometimes followed by chemical element symbols to indicate compositional modifications to the original grade. The other is termed the
17、 “Alloy Type” approach, which uses tradition-based three or four digit designations for certain original grades, sometimes followed by one or more chemical element symbols which indicate compositional modifications from the original. In both approaches, classification is based upon the chemical comp
18、osition of the product. In many cases a given product can be classified using both approaches, because the composition ranges, although slightly different, overlap to a considerable extent, in the two approaches. Application of either type of classification designation (or both where suitable) ident
19、ifies a product as classified according to this International Standard. Many, but not all, commercial products addressed by this International Standard can be classified using both approaches, and suitable products may be so marked. The classification according to system A is mainly based on EN 1207
20、2. The classification according to system B is mainly based upon standards used around the Pacific Rim. For stainless steel welding consumables, there is no unique relationship between the product form (wire electrode, wire or rod) and the welding process used (gas-shielded metal arc welding, gas tu
21、ngsten arc welding, plasma arc welding or submerged arc welding). For this reason, the wire electrodes, wires or rods may 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.
