EN ISO 5178:2011 (E) DIN EN ISO 5178:2011-05 31 ScopeThis International Standard specifies the sizes of test specimens and the test procedure for carrying out longitudinaltensile
22、tests on cylindrical test specimens in order to determine the mechanical properties of weld metal in a fusionwelded joint.This International Standard applies to metallic materials in all forms of product with joints made by any fusionwelding process, having joint sizes that are sufficient to obtain
23、cylindrical test specimens with dimensions inaccordance with ISO 6892.Unless specified otherwise for specific points in this International Standard, the general principles of ISO 6892apply.2 Normative referenceThe following normative document contains provisions which, through reference in this text
24、, constitute provisions ofthis International Standard. For dated references, subsequent amendments to, or revisions of, this publications donot apply. However, parties to agreements based on this International Standard are encouraged to investigate thepossibility of applying the most recent edition
25、of the normative document indicated below. For undated references,the latest edition of the normative document referred to applies.

26、reasing tensile load is continuously applied until rupture occurs in a cylindrical test specimen takenlongitudinally from the weld metal in a welded joint.Unless otherwise specified, the test shall be carried out at ambient temperature (23 Gb1 5) C.4 Symbols and abbreviated termsThe symbols and abbr
27、eviated terms to be used for the longitudinal tensile tests are specified in ISO 6892.EN ISO 5178:2011 (E) DIN EN ISO 5178:2011-05 45 Removal of test specimens5.1 LocationThe test specimen shall be taken longitudinally from the welded joint of the manufactured product or from the testpiece. After ma
28、chining, the parallel length of the test specimen shall consist only of weld metal (see Figures 1and 2).To enable correct positioning of the test specimen in the joint, the joint cross-section at both ends of the testspecimen can be macroetched.5.2 MarkingEach test piece shall be marked in order to
29、identify its exact location in the manufactured product or in the jointfrom which it has been removed.Each test specimen shall be marked in order to identify its exact location in the test piece from which it has beentaken.When removed from the test piece, each test specimen shall be marked.5.3 Heat
30、 treatment and/or ageingNo heat treatment shall be applied to the welded joint or to the test specimen unless it is specified or permitted bythe relevant application standard dealing with the welded joint to be tested. Details of any heat treatment shall berecorded in the test report. If natural age
31、ing of aluminium alloys takes place, the time between welding and testingshall be recorded.NOTE The presence of hydrogen in ferrous weld metals may adversely affect the test results and suitable hydrogenrelease treatment may be necessary.5.4 Extraction5.4.1 GeneralThe mechanical or thermal processes
32、 used to extract the test specimen shall not change the properties of the testspecimen in any way.5.4.2 SteelShearing is excluded for thicknesses G3e 8 mm. If thermal cutting or other cutting methods which could affect the cutsurfaces are used to cut the test specimen from the welded plate, or from
33、the test piece, the cuts shall be made ata distance W 8 mm from the surfaces of the final parallel length of the test specimen. Thermal cutting shall not beused parallel to the original surface of the welded plate or of the test piece.5.4.3 Other metallic materialsShearing and thermal cutting are ex
34、cluded and only machining (e.g. sawing and turning) shall be used.EN ISO 5178:2011 (E) DIN EN ISO 5178:2011-05 55.5 Machining of test specimens5.5.1 LocationUnless specified otherwise in the particular application standard dealing with the welded joint under examination,the test specimens shall be t
35、aken from the centre of the weld metal as shown in Figure 1 and the cross-section asshown in Figure 2. In the case where the test specimen is not taken from mid-thickness, the distance from thesurfaces, t1, shall be recorded (see Figures 2 a) and b). In the case of very thick or double-sided welded
36、joints,more than one test specimen may be taken at different locations through the thickness (see Figure 2 c), in whichcase the distances, t1and t2, of each test specimen in the joint cross-section shall be recorded.Figure 1 Examples of location of test specimens Longitudinal plane sectionEN ISO 517

If this is not possible, the diameter shall be as large as possible but notless than 4 mm. The actual size s
39、hall be recorded in the test report.The gripped ends of the test specimens shall be compatible with the tensile testing machine used.5.7 Surface qualityThe tolerances specified in ISO 6892 shall apply.Strain-hardening or excessive heating of the material shall be avoided.6 Conditions of testingThe t
