| 摘 要： | 焊接热输入和冷却时间是影响焊接温度场分布的重要参数.本文利用有限元软件ANSYS对X80管线钢复合坡口多道焊的焊接过程进行二维模拟,研究每道填充焊层T8/5的变化规律.结果表明,热输入对T8/5的影响最大;T8/5随热输入的增加而增大;由于前一道焊对后一道焊的预热作用,T8/5随焊道数的增多而增大;当层间温度等于预热温度时,各层的T8/5趋于一致.合理选择预热温度和层间温度可以有效控制各焊道的T8/5. |

| Abstract: | Welding heat input and cooling time are important technical parameters that affect the welding temperature distribution field.2D simulation of multi-pass compound groove of welding process for X80 pipeline steel is carried out by finite element software ANSYS,in which the distribution of T_(8/5) of welding filling layer is analyzed.The results show that the effect of heat input to T_(8/5) is significant.The T_(8/5) becomes longer with the increase of the heat input.Because of the obvious preheat influence o... |
