Abstract: Bending test was a test method to determine the plastic deformation capacity of welded joints. The relevant domestic and foreign standards for weld bending test of metal materials were introduced briefly, and compared and analyzed the differences between the current standards GB/T 2653—2008 and ISO 5173:2023. It was suggested that the coordination between different standards should be enhanced as far as possible in combination with the actual situation in China, so as to make the newly revised standard clearer and easier to operate.
