What is the acceptable condition after a bend test?

The condition that is considered acceptable after a bend test in the context of welding inspections is that no defect may exceed 1/8" or half the nominal wall thickness, whichever is smaller. This criterion ensures that the integrity of the welded joint is maintained and that the weld has sufficient ductility and strength in its intended application.

A defect exceeding this measurement could indicate weaknesses that compromise the overall performance of the weld under operational conditions. Therefore, adhering to this standard is crucial for safety and reliability in pipeline construction and maintenance.

The other conditions mentioned may seem relevant, but they do not encompass the comprehensive standard of acceptability as specified in industry guidelines. The specific measurement limits for defects provide a clear and quantifiable parameter for evaluating the weld's quality.
