| Abstract: | The guide bending test can inspect many properties of samples,including judging plasticity of weld and HAZ,inner defects of welded joints,weld compactness,coordinating deformation ability of welded joints in different areas.The guide bending test is conducted in the routine tests of SAW pipe,welding procedure qualification test and repair welding qualification test.It briefly introduced the relevant regulations to guide bending tests in commonly applied standards for transporting oil and gas,analyzed various factors of occurring face bend and foot bend unqualified samples during guide bending test,and gave various measures to prevent generating unqualified guide bending. |
