![]() Not exhibit any discontinuities greater than 1/8 in in length.Be bent according to the specifications of the code (different bend radii are specified depending on the base metals yield strength). ![]() In order to pass weld soundness by bend tests the specimens must: Additional requirements apply for tests that have an open root (no backing).Undercut must not exceed 1/32 in in depth.The weld must not exceed 1/8 in reinforcement.Craters must be filled to the full cross section of the weld.In order to pass visual inspection the weld must: ![]() Soundness is tested by performing bend tests or by radiographic inspection. In order for the welder to successfully pass this test, he or she must pass both visual inspection and meet the weld soundness acceptance criteria. It should be 1 in wide (3 in wide if it will not be removed when radiographic inspection is used for evaluating weld soundness in lieu of bend tests) and ΒΌ in to 3/8 in thick. The backing bar should extend the length of the test plates or could be slightly longer to allow for a run-on and run-off tabs. Welder performance qualification test for limited thickness.
