6、lding and allied processes” in collaboration with Technical Committee CEN/TC 121 “Welding and allied processes” (Secretariat: DIN, Germany).

This International Standard is a “cohabitation standard” in which two different approaches to the same subject are specified, designated as “system A” and “system B”. System A classification mainly reflects the European approach,
8、 while classification according to system B is mainly based on standards used around the Pacific Rim. When using this standard, it is to be established according to which classification designation (A or B) the product is manufactured and delivered. The DIN Standards corresponding to the Internation
9、al Standards referred to in this document are as follows: ISO 544 DIN EN ISO 544 ISO 3690 DIN EN ISO 3690 ISO 6847 DIN EN ISO 6847 ISO 13916 DIN EN ISO 13916 ISO 14174 DIN EN ISO 14174 ISO 14344 DIN EN ISO 14344 ISO 15792-1:2000 DIN EN ISO 15792-1:2012-01 ISO 15792-2:2000 DIN EN ISO 15792-2:2008-08

39、national 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
40、 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
41、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 a
42、re to 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 is i
43、ntended to 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 i
44、n 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 in production joints because of differences in welding procedures such as electrode size and parent material composition.
45、EN ISO 14171:2016 (E) DIN EN ISO 14171:2016-12 5 1 ScopeThis International Standard specifies the 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 g
46、rain steels with 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.This Internation
47、al Standard 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.a) Paragraphs and tab
48、les which carry the suffix letter “A” are applicable only to electrode/flux combinations and wire electrodes classified using the system based upon the yield strength and the average impact energy for weld metal of 47 J, in accordance with this International Standard.b) Clauses and tables which carry the suffix letter “B” are applicable only to electrode/flux combinations and wire electrodes classified using the s
