摘要
详细介绍了双面螺旋埋弧焊焊趾部位缺欠的超声检测工艺和方法,通过金相分析验证了其有效性。分析了焊趾部位缺欠对焊缝力学性能的影响及焊趾部位缺欠产生的原因。为了我国油气输送管网建设的百年大计,提出应通过订货附加技术条件来弥补现行的焊趾部位缺欠超声波验收标准的不足。
It introduces clearly UT inspection procedure and methods on submerged arc weld toes indication,and also its effectiveness is verified with micro-metal analysis.Also it analysis weld toes indication causes and weld toes indication influence on mechanical property.In order to national oil-gas pipelines plan,it also raises the shortage of practical Standards and also states the measurement to revise the standards to UT inspection on weld toes in technical requirements.
