These tests can be peformed immediately after welding and will give information about types, sizes and distribution of internal imperfections such as porosity, cracks, lack of fusion, lack of penetration and solid inclusion on the fracture surface. They will indicate whether any imperfections revealed are within the specified level. These simple tests may be carried out preferably in workshops with suitable devices. The fracture can be indiced by bending or by tension under static or dynamic load. The use of fracture test may be required by the relevant application standard, by the agreement between the parties concerned or may be used by the manufacturr to check his welding quality. This standard applies to butt and fillet fusion welded joints in plates, pipes or branch connections with a thickness ≥ 2 mm carried out by all fusion welding processes according to EN 24063. The principles of these tests may also be applied to some other welding processes. The standard specifies several test methods and test pieces. In the nock-break test, fracture is produced along the centerline of the weld. The recommended type may be defined by the relevant pplication standard as well a by contract between the parties concerned at the stage of contract review, or at the latest design review, or by the manufacturer for his own purposes.
