Endorsement notice The text of ISO 3580:2010 has been approved by CEN as a EN ISO 3580:2011 without any modification. EN ISO 3580:2011 (E) DIN EN ISO 3580:2011-05 3Introduc

24、tion This International Standard proposes a method for classification of covered electrodes, in terms of chemical composition of the all-weld metal (system A) and in terms of tensile strength and chemical composition (system B). The mechanical properties of all-weld metal test specimens used to clas

25、sify the electrodes vary from those obtained in production joints because of differences in welding procedure such as electrode diameter, width of weave, welding position and material composition. The classification according to system A is mainly based on EN 1599:19971. The classification according

26、 to system B is mainly based upon standards used around the Pacific Rim. EN ISO 3580:2011 (E) DIN EN ISO 3580:2011-05 41 Scope This International Standard specifies requirements for classification of covered electrodes, based on the all-weld metal in the heat-treated condition, for manual metal arc

27、welding of ferritic and martensitic creep-resisting and low alloy elevated temperature steels. This International Standard is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and impact

28、energy of the all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of the all-weld metal. a) Paragraphs and tables which carry the suffix letter “A” are applicable only to electrodes classified to the system based upon chemical composition, with requirem

29、ents for the yield strength and impact energy of the all-weld metal under this International Standard. b) Paragraphs and tables which carry the suffix letter “B” are applicable only to electrodes classified to the system based upon the tensile strength and the chemical composition of all-weld metal

30、under this International Standard. c) Paragraphs and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all covered electrodes classified under this International Standard. For comparison purposes, some tables include requirements for electrodes classifi

31、ed according to both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the particular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system

32、is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, and/or its packaging, may be marked with the classification in eith

33、er or both systems. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

In most cases, a given commercial product can be classified in both systems. Then either or both classification designations can be used for the prod

39、uct. The classification includes all-weld metal properties obtained with a covered electrode as given in 3A and 3B. The classification is based on the electrode size 4,0 mm with the exception of the symbol for welding position which is based on ISO 15792-3. 3A Classification by chemical compositionT

40、he classification is divided into six parts: 1) the first part gives a symbol indicating theproduct/process to be identified; 2) the second part gives a symbol indicating thechemical composition of the all-weld metal (seeTable 1); 3) the third part gives a symbol indicating the typeof electrode cove

41、ring (see 4.4A); 4) the fourth part gives a symbol indicating thenominal electrode efficiency and type of current (seeTable 4A); 5) the fifth part gives a symbol indicating thewelding position (see Table 5A); 6) the sixth part gives a symbol indicating thehydrogen content of the deposited metal (see

42、Table 6). 3B Classification by tensile strength and chemical composition The classification is divided into five parts: 1) the first part gives a symbol indicating the product/process to be identified; 2) the second part gives a symbol indicating the strength of the all-weld metal (see Table 2); 3)

43、the third part gives a symbol indicating the type of electrode covering, the type of current, and the welding position (see Table 3B); 4) the fourth part gives a symbol indicating the chemical composition of all-weld metal (see Table 1); 5) the fifth part gives a symbol indicating the hydrogen conte

44、nt of deposited metal (see Table 6).EN ISO 3580:2011 (E) DIN EN ISO 3580:2011-05 6In order to facilitate the use of this InternationalStandard, the classification is split into two sections:a) Compulsory section This section includes the symbols for the typeof product, the chemical composition and t
