1 Scope
This standard specifies bend test methods on welded joints.
This standard is applicable to the bend tests of metallic material melt welded joints.
2 Terms and Definitions
For the purposes of this International Standard, the following terms and definitions apply.
2.1
Face bend test specimen for a butt weld, FBB
Specimen for which the surface in tension is the side which contains the greater width of the weld or the side from which the welding arc was first applied, applicable to both transverse and longitudinal butt weld specimens (See Figures 1 and 3).
2.2
Root bend test specimen for a butt weld, RBB
Specimen for which the surface in tension is the side opposite to that of the face butt weld bend test specimen (See Figures 1 and 3).
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 2)
2.4
Face bend test specimen for cladding without a butt weld, FBC
Specimen for which the cladding is in tension (See Figure 4)
2.5
Side bend test specimen for cladding without a butt weld, SBC
Specimen for which the cross-section of the cladding overlay is in tension (See Figure 5).
2.6
Face bend test specimen for cladding with a butt weld, FBCB
Specimen for which the cladding is in tension and which contains a butt weld (See Figures 6)
2.7
Side bend test specimen for cladding with a butt weld, SBCB
Specimen for which the cross-section is in tension and which contains a butt weld (See Figures 7)
3 Principles
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 ambient temperature (23± 5) °C. The test shall be made in accordance with one of the methods described in clause 6.
