    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

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

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
