摘要
提出了3种螺旋缝埋弧焊管焊接补焊工艺评定标准,即GB/T 9711—2011标准附录D、ASMEⅨ—2013和NB/T 47014—2011;从补焊评定焊缝焊接条件、焊缝力学性能取样方向及验收标准等方面,分析其差异性;并给出了具体的补焊焊接取样方法及力学性能验收标准。
Presented here in the essay are the three standards as for evaluating the repair-welding process for the SAWH pipe, namely GBFF 9711--2011, Appendix D, ASME IX--2013 and NB/T 47014--2011. The differences between these standards are analyzed in terms of repair-welding evaluation of welding conditions for the weld seam, direction of sampling for the weld mechanical property test and the acceptance criteria, etc. Moreover, specific sampling method and mechanical property acceptance criteria for repair-welding are presented.
