压力容器焊接缺陷的安全评定一直是人们关注的问题。本文研究了单面焊未焊透对压力容器用钢焊接接头强度和寿命的影响,给出了含未焊透缺陷焊接结构的极限载荷和疲劳扩展寿命的估算方法。
Safety assessment of pressure vessel welding defects has always been a concern. In this paper, the influence of single-side welding on the strength and life of steel welded joints of pressure vessel was studied. The method of estimating the ultimate load and fatigue life of welded structure with non-welded defects was given.
