| The depth of the notch is approximately 2 to 3mm depending on the thickness of the weld | Contact LMATS' laboratory nearest to you on 1300 707 365 in Melbourne, Sydney, Albury, Newcastle, Brisbane or Perth for further information |

| LMATS has several other innovative advanced NDT capabilities | This test is performed to reveal internal imperfections such as slag inclusion, lack of fusion, incomplete penetration, porosity, etc in a butt weld |
An artifical notch or a groove is intentionally introduced by a hacksaw or a cutting disc on the weld face, along the primary axis of the weld to facilitate fracture in the centre line of the weld.
21| The weld specimen is then mechanically bent to fracture along the weld centre line and the cross section is visually examined for imperfections | 2 and ASME IX QW 182 are some of the common standard method utilised to perform this test |
