摘要
薄壁金属的连接和成型采用微束等离子弧焊的方法具有较多优点。微束等离子孤焊的工艺参数对焊缝的形状和焊接质量都有影响。文章研究了不同的焊接速度对12Cr18Ni10Ti薄板在腐蚀性介质中的低用腐蚀疲劳寿命的影响。结果表明,在其他工艺参数相同的情况下,焊接速度在60～125 m/h内变化,焊接试板在大气和3％NaCl溶液中的低用腐蚀疲劳寿命相差较大。
Connecting and forming metal sheets by micro-ray plasma arc welding process offers many advantages.Whereas the welding process parameters of micro-ray plasma arc welding affect the weld shape and welding quality.The impact of different welding speeds on the low-cycle corrosion fatigue life of 12Cr18Ni10Ti steel sheets in corrosive media was studied and the results showed that,at the same welding process parameters,the low-cycle corrosion fatigue life of steel sheets welded at the speeds ranging from 60 m/hr to 125 m/hr in 3% NaCl solution varied greatly.
