摘要:
焊缝气孔是一种体积性缺欠,对焊缝强度的影响不可忽视,因而气孔缺欠的判定是焊缝缺陷评判的重要内容之一。链状气孔是螺旋埋弧焊管焊缝中最常见的缺欠之一,因其气孔数量多且间距不等,因而准确判定具有一定的难度,且评判过程比较繁琐。介绍了链状气孔常用的评定方法,即以点数评级和以气孔直径评级,说明了评定链状气孔应注意的事项。
Abstract:
Porosity in weld is a kind of cubage imperfection,which can not be ignored that it has great influences to weld intensity.Therefore,the verification to porosity imperfection is one of important items in weld defect judgment.The chain porosity is one kind of common imperfections in weld of SSAW pipe.There are some difficulties to actually verify and complicated determination course due to quantity of porosity and irregular interval.This article introduced common method in verifying chain porosity,they are using points quantity and porosity diameter to verify.It outlines caution proceedings in verifying chain porosity.
