摘要:
焊缝导向弯曲试验的目的是检查焊接接头的完好性和塑性以及材料的焊接工艺和表面缺陷。在西气东输二线用X80级螺旋焊管焊缝导向弯曲试验中,由于钢管具有高强度、高韧性、大壁厚的特点,其弯曲试验明显不同于低钢级薄板的焊缝弯曲试验,在试验中发现了大量因试样加工硬化造成的表面微裂纹,也发现一些由于夹渣、气孔等原因引起的表面破裂,对于此类现象应该进行正确的分析和评判。
Abstract:
The purpose of weld guide bending test is to detect plasticity of welding joint,welding process and surface defects of materials.The weld bending test of X80 grade SSAW pipe used in the Second West to East Gas Pipeline Project was obvious different with that of thin steel plate with low steel grade,and these steel pipes possess characteristics of high strength,high toughness and heavy thickness.The surface tiny crack generating by sample hardening were found in test,and some surface fracture caused by inclusion and gas pocket,and these appearance should be correctly analyzed and judged.
