摘要:
利用夏比冲击、显微硬度和拉伸试验对6种焊材在相同补焊工艺下的全壁厚刨透补焊焊缝进行了性能对比研究, 筛选出焊缝性能较优的对应补焊焊材。并以此焊材作为 X80M级1 219 mm ×18.4 mm螺旋埋弧焊管焊缝缺陷手工修补用专用焊材,进行了不同补焊工艺参数的全壁厚刨透补焊试验,并对补焊焊缝进行低温冲击试验,通过比较确定出X80M级1 219 mm×18.4 mm螺旋埋弧焊管全壁厚刨透补焊工艺方案。结果表明, 上海焊接器材厂生产的SH J557焊条用于X80M级1 219 mm×18.4 mm螺旋埋弧焊管焊缝缺陷全壁厚刨透手工修补更为合适,各项性能指标更高;确定的补焊工艺参数合理可行,确保了补焊焊缝的质量和钢管的批量化生产。
Abstract:
The properties of full thickness repair welding seam that generated by 6 kinds of welding material under the same repair welding condition were comparatively investigated by V-notch Charpy impact toughness test, micro-hardness test and tensile test, and selected out the repair welding material matching with better weld performance. Taking the selected welding material as special welding material for manual repairing the weld defect in 1 219 mm×18.4 mm X80M SAWH pipe, the full thickness repair welding tests for the different welding process parameter were conducted, and the low temperature impact test for repair weld was carried out. Finally, it determined the repair welding process for 1 219 mm×18.4 mm X80M SAWH pipe. The results indicated that the SHJ557 welding electrode produced by Shanghai Welding Equipment Factory is more suitable for the above repair welding process of 1 219 mm×18.4 mm X80M SAWH pipe, the various performance indexes are higher; the determined repair welding process parameters are reasonable, it ensures the quality of repair weld and the mass production of steel pipe.
