摘要
对计算焊接冷却时间t_(8/5)的理论经验公式进行了验证,首先利用热电偶和函数记录仪等设备测量了单丝埋弧堆焊X80管线钢板的t_(8/5),然后采用理论经验公式计算得到相应的t_(8/5),最后利用概率论的方法分析t_(8/5)测量值和计算值的吻合程度,分析结果表明两者是吻合的,因此理论经验公式可以用来计算管线钢在单丝埋弧焊接过程中的t_(8/5),可以为合理制定X80管线钢的焊接工艺提供了重要依据。
The weld cooling time t8/5 theoretical empirical formula was verified.t8/5 of single wire submerged arc welding in X80 pipeline steel was measured by thermocouple and function recorder first,then t8/5 was calculated by theoretical empirical formula,the coincidence between measured values and calculated values were analyzed by probability theory at last.The results show that the calculated values coincide with the measured values.So the theoretical empirical formula can be used to calculate t8/5 of single wire submerged arc welding of pipeline steel,and the theoretical empirical formula can provide important reference for making reasonable welding technology of X80 pipeline steel.
