In bend test qualification, what indicates a pass?

In bend test qualification, the focus is on the weld's ductility and structural integrity when the joint is bent to the prescribed angle. The specimen is bent to the required radius, and a pass is achieved when the weld zone remains crack-free after bending, showing the weld and surrounding metal can deform without fracturing. Cracking or separation in the weld metal or heat-affected zone indicates the joint cannot withstand plastic deformation and thus fails. The test isn't about just measuring the bend radius, surface finish, or the welder’s experience; those factors may be part of the setup, but the pass/fail outcome rests on whether cracks appear in the weld area under bending.
