Includes standard P-1 plunger. The qualification of welders can be accomplished by making radiographs or by using bend tests, as required by many welding codes. The stress condition which essentially determines the loading of the welded joint and thus causes the cracking can be changed by various clamping conditions. The heat from the welding process causes local tensile residual stresses at the weld toe, geometric distortions which lead to additional bending stress and changes in material properties near the weld. I buddy of mine does a lot of industrial fab work. HAJJAR1, and Sean C.

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. If you don't have 100% penetration, there will be cracks, or if the penetration is really poor, the edges of the 2 sides will simply pull apart. Guided bend tests are usually taken transverse to the weld axis and may be bent in plunger type test machines or in wrap-around bend test jigs. No mandrel bends there are no mandrel bend machines here and bring all the curves from the US was a bit pricey. Weld quality assurance is the use of technological methods and actions to test or assure the quality of welds, and secondarily to confirm the presence, location and coverage of welds. all over the world.
