摘要
针对某钢厂研制的08Ni DR钢板进行试验,根据确定的焊接工艺和焊接参数分别研究焊条电弧焊和埋弧自动焊焊接接头的拉伸性能、系列冲击性能等。各项力学性能表明,焊接接头综合力学性能优良,可满足温度不低于-100℃的低温压力容器的设计要求。
Experimental studies are conducted on welding of 08Ni3DR steel developed by one steel mill. According to the determined welding technology and parameters,mechanical properties of welded joints of 08Ni3DR steels welded by SMAW and SAW respectively, such as tensile,series impact and oilier properties are systematically studied. The results show that welded joints of 08Ni3DR steel have excellent eomprehensive mechanical properties,and can meet the design requirements of pressure vessel which applied in temperature not lower than -100℃.
