AS NZS 2205.3.1 pdf download.Destructive tests on welds in metallic materials
1  Scope
This International Standard specifies a method for making transverse root, face and side bend tests on test specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to assess ductility and/or absence of imperfections on or near the surface of the test specimen. It also gives the dimensions of the test specimen. In addition, this International Standard specifies a method for making longitudinal root and face bend tests to be used instead of transverse bend tests for heterogeneous assemblies when base materials and/or filler metal have a significant difference in their physical and mechanical properties in relation to bending. This International Standard applies to metallic materials in all forms of product with welded joints made by any fusion arc welding process.
2  Terms and definitions
For the purposes of this document, the following terms and definitions apply. 2.1 transverse face bend test specimen for a butt weld TFBB specimen for which the surface in tension is the side that contains the greater width of the weld or the side from which the welding arc was first applied, applicable to transverse butt weld specimens See Figure 1 2.2 transverse root bend test specimen for a butt weld TRBB specimen for which the surface in tension is the side opposite to that of the face butt weld bend test specimen, applicable to transverse butt weld specimens See Figure 2 2.3 transverse side bend test specimen for a butt weld SBB specimen for which the surface in tension is a cross-section of the weld See Figure 3 2.4 longitudinal face test specimen for a butt weld root bend test specimen for a butt weld LFBB LRBB specimen whose direction is parallel to butt weld direction, applicable to face and root bend specimens See Figure 4 2.5 face bend test specimen for cladding without a butt weld FBC specimen for which the cladding is in tension, applicable to both transverse and longitudinal specimens See Figure 5 2.6 side bend test specimen for cladding without a butt weld SBC specimen for which the cross-section of the cladding overlay is in tension, applicable to both transverse and longitudinal specimens See Figure 6 2.7 face bend test specimen for cladding with a butt weld side bend test specimen for cladding with a butt weld FBCB SBCB specimen for which the cladding is in tension or for which the cross-section of the cladding overlay is in tension and which contains a butt weld See Figures 7 and 8
5  Preparation of test specimens
5.1  General Specimens shall be prepared in such a manner that the preparation does not affect either the base material or the weld metal. 5.2  Location For transverse bend testing of butt welds, the test specimen shall be taken transversely from the welded joint of the manufactured product or from the welded test piece in such a way that after machining the weld axis will remain in the centre of the test specimen or at a suitable position for testing. For longitudinal bend testing of butt welds, the test specimen shall be taken longitudinally from the welded joint of the manufactured product or from the welded test piece. The location and orientation of bend test specimens of cladding material shall be specified by the application standard or by agreement between the contracting parties. 5.3  Marking Each test piece shall be marked to identify its exact location in the manufactured product or in the joint from which it has been removed. If required by the relevant application standard, the direction of working (e.g. rolling or extrusion) shall be marked. Each test specimen shall be marked to identify its exact location in the test piece from which it has been removed. 5.4  Heat treatment and/or ageing No heat treatment shall be applied to the welded joint or to the test specimen unless it is specified or permitted by the relevant application standard dealing with the welded joint to be tested. Details of any heat treatment shall be recorded in the test report. If natural ageing of aluminium alloys takes place, the time between welding and testing shall be recorded.
