摘　　要：为充分了解HFW焊管焊缝沟槽腐蚀机理,及其对高频电阻焊管力学性能的影响,从而探索出有效降低HFW焊管沟槽腐蚀敏感性的方法,从沟槽腐蚀影响规律、测试方法等方面对国内外现阶段沟槽腐蚀研究成果进行分析汇总,着重分析了几种主要的沟槽腐蚀敏感性测试方法,对其优劣性进行了对比。同时,根据沟槽腐蚀研究现状以及相关知识产权的情况,发现目前国内外尚无统一标准的焊缝沟槽腐蚀深度的测量设备或装置,对沟槽腐蚀敏感系数临界值也缺乏工程依据,其失效判定的有效性有待进一步探讨。In order to fully understand the mechanism of HFW welded pipe weld groove corrosion and its influence on the mechanical properties of resistance welded pipe,and explore the methods to effectively reduce the groove corrosion sensitivity of welded pipe,the research results of groove corrosion at home and abroad at this stage are analyzed and summarized from the aspects of groove corrosion impact law,testing methods and so on.Several main groove corrosion sensitivity test methods are emphatically analyzed,and their advantages and disadvantages are compared.At the same time,according to the research status of groove corrosion and relevant intellectual property rights,it is found that there is no unified standard equipment or device for measuring the groove corrosion depth of weld at home and abroad,and there is also a lack of engineering cases for the critical value of groove corrosion sensitivity coefficient,and the effectiveness of its failure determination needs to be further discussed.
