AS NZS 2205.3.1:2020 pdf free 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
3  Principle
Submitting a test specimen, taken transversely or longitudinally from a welded joint, to plastic deformation by bending it, without reversing the bending direction, in such a way that one of the surfaces or cross-sections of the welded joint is in tension.
Unless otherwise specified, the test shall be carried out at an ambient temperature of (23 ± 5) °C.
The test shall be made in accordance with one of the methods described in Clause 6.
