29、t different approaches in the global market to classifying a given wire electrode, tubular cored electrode or 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) id

30、entifies a product as classified in accordance with this International Standard. The classification in accordance with system A is mainly based on EN 12070:19992. The classification in accordance with system B is mainly based upon standards used around the Pacific Rim. This International Standard pr

31、ovides a classification system for solid wire electrodes in terms of their chemical composition, solid wire electrodes and 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

32、 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 metal. Users should note that matching weld metal yield strength to parent metal yield strength does not necessarily ensure that the

33、weld metal tensile strength matches that of the parent material. Where the application requires matching tensile strength, therefore, selection of the consumable should be made by reference to column 3 of Table 1A or Table 1B, as appropriate. Although combinations of wire electrodes and fluxes suppl

34、ied by individual companies can have the same classification, the individual wire electrodes and fluxes from different companies are not interchangeable unless verified in accordance with this International Standard. It should be noted that the mechanical properties of all-weld metal test pieces use

35、d to classify the wire electrodes vary from those obtained in production joints because of differences in welding procedure, such as electrode size, welding position and material composition. 4DIN EN ISO 24598:2012-08 EN ISO 24598:2012 (E) 1 Scope This International Standard specifies requirements f

36、or classification of solid wire electrodes, tubular cored electrodes and electrode/flux combinations (all-weld metal deposits) for submerged arc welding of creep resisting and low-alloy elevated-temperature steels. One electrode can be tested and classified with different fluxes. The solid wire elec

37、trode is also classified separately based on its chemical composition. This International Standard is a combined specification providing for classification utilizing a system based upon the chemical composition of the solid wire electrode and all-weld metal deposit, or utilizing a system based upon

38、the tensile strength of the all-weld metal deposit and the chemical composition of the solid wire electrode and all-weld metal deposit obtained with the electrode/flux combination. a) Clauses, subclauses and tables which carry the suffix letter “A” are applicable only to solid wire electrodes, tubul

39、ar cored electrodes and all-weld metal deposits classified in accordance with the system based upon chemical composition. b) Clauses, subclauses and tables which carry the suffix letter “B” are applicable only to solid wire electrodes, tubular cored electrodes and all-weld metal deposits classified

40、in accordance with the system based upon the tensile strength of all-weld metal deposits and the chemical composition of solid wire electrodes and all-weld metal deposits. c) Clauses, subclauses and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all

45、cation designations are based upon two approaches to indicate the chemical composition of the solid wire electrode, the chemical composition of the all-weld metal deposit obtained with a solid wire electrode or tubular cored electrode, and the tensile properties and impact properties of the all-weld

46、 metal deposits obtained with a given electrode/flux combination. The two designation approaches include additional designators for some other classification requirements, but not all, as is clear from the provisions given in this International Standard. In many cases, a given commercial product can

47、 be classified in accordance with both systems. Then either or both classification designations can be used for the product. A solid wire electrode shall be classified in accordance with its chemical composition as given in Table 3. An all-weld metal deposit from a solid wire electrode or tubular co

48、red electrode shall be classified in accordance with the all-weld metal deposit composition, as given in Table 4, obtained with a particular flux. When the solid wire electrode or tubular cored electrode is classified in combination with a flux for submerged arc welding, the classification shall be prefixed with a symbol in accordance with Clause 4 as appropriate. 3A Classification by chemical composition 3B Classification by tensile strength and chemical composition The classifica
