焊管常用标准对焊缝接头拉伸试样是否去除焊缝余高要求不一。本文从焊接接头拉伸的实际意义出发,探讨了是否去除焊缝余高及断裂位置对试验结果的影响。不去除焊缝余高的情况,更偏重于焊缝结构的整体强度,而不是严格意义上的焊接接头的抗拉强度。为避免分歧及便于对比,西气东输二线管道工程技术条件中统一规定了焊接接头拉伸试验必须去除焊缝余高,且报告断裂位置。 Welded pipe commonly used standard weld joint tensile test specimen whether to remove the weld remaining high requirements vary. In this paper, starting from the practical significance of the tensile welding joint, whether to remove the weld height and location of fracture on the test results. Not remove the remaining high weld situation, more emphasis on the overall strength of the weld structure, rather than the strict sense of the tensile strength of welded joints. In order to avoid disagreement and facilitate comparison, the technical conditions of the second-phase West-East Gas Pipeline Project stipulate uniformly that the weld joint tensile test must remove the excess weld height and report the fracture location.
