22、N EN ISO 15792-2:2008-08 IntroductionConsumables for both submerged arc welding and metal arc welding with tubular cored electrodes can be suitablefor welding by the single- or two-run technique and the methods for testing and classification are specified. When awelding consumable is offered for use
23、 by these techniques, it should be noted that all-weld metal test pieces maynot be required by the consumable classification standard.Test conditions prescribed and results required should not be considered to be requirements or expectations for aprocedure qualification.4 DIN EN ISO 15792-2:2008-08
24、EN ISO 15792-2:2008 (E) 1 ScopeThis part of ISO 15792 specifies the preparation of butt weld test pieces and specimens. The purpose is to definetest methods in order to determine strength and impact strength of the welded joint when testing weldingconsumables with single-run and two-run technique, n
25、ot suitable for electro-slag or electro-gas welding.This part of ISO 15792 is applicable to welding consumables for arc welding of steel.2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions ofthis part of ISO 15792.

30、on of the test pieceThe plates of the test piece shall be preset or restrained in such a way that a sufficiently flat test piece is producedfor extraction of specimens. The welded test piece shall not be straightened. A suitable backing system for single-run technique may be used. Run-on and run-off
31、 plates may be used. See Table 1.6 Welding conditionsThe test piece shall be welded in the flat position. The welding shall be started at room temperature or afterapplying any preheating if required by the welding consumable standard. The interpass temperature shall be inaccordance with the welding
32、consumable standard.The preheating and interpass temperatures shall be measured using temperature indicator crayons, surfacethermometers or thermocouples, see ISO 13916.The welding conditions used, such as current, voltage, travel speed, weld bead size, shall be within the rangerecommended by the ma
33、nufacturer and where the test is performed for classification purposes in accordance withthe limits specified in the relevant consumable standard.7 Heat treatmentAll heat treatments required for the butt weld, except hydrogen removal treatment shall be carried out on thecompleted test piece, or on s
34、ections thereof with a machining allowance.The heat treatments are specified in standards relating to welding consumables.Hydrogen removal treatment may be carried out on the test piece for tensile testing before or after final machining.The test piece may be held at a temperature not exceeding 250
35、C for up to 16 h.8 Position of specimens, specimen dimensions and testingFigures 1 and 2 show the position of the tensile test specimen and of the notched impact specimens. The test piecemust be divided by cutting (machining) or by thermal cutting. In the case of thermal cutting, machining allowance
36、sof 10 mm at least on either side shall be provided for the subsequent machining of the specimens.The specimens for transverse tensile tests and testing shall be in accordance with ISO 4136. Table 2 ofISO 4136:2000 shall be used for specimen dimensions.When applicable, the specimens for the impact t
37、est and testing shall be in accordance with ISO 9016. The impactspecimen shall be in accordance with the designation VWT 0/b in ISO 9016:2000. The position of the impactspecimens shall be at the midline of the plate thickness for types 2.1 and 2.2 and from the last welded run asshown in Figure 2 for
38、 type 2.5. Impact specimens are not applicable for type 2.3 and 2.4.The size of impact specimens shall be 10 mm Gb4 10 mm. If impact testing is required for types 2.3 and 2.4 subsizespecimens 5 mm Gb4 10 mm shall be used.NOTE It is recommended that the test piece be subjected to radiographic and/or
39、macrographic examination of theprepared and etched surface to ascertain if there are any defects in the weld prior to the preparation of test specimens.9 RetestsIf any test fails, repeat tests shall be performed in accordance with relevant requirements.6 DIN EN ISO 15792-2:2008-08 EN ISO 15792-2:200
