摘要:
选取12Cr1MoV异质接头作为试验材料,研究了焊接电压、焊接电流和焊前预热温度三种主要的焊接工艺参数之间的耦合关系,并通过试验和运用有限元法对焊接过程进行实例分析与模拟验证。结果表明:焊接残余应力分布情况曲线特征与模拟结果相吻合;焊接残余应力模拟影响区域与试验结果测量值相符;焊接电压、焊接电流能够较为集中的进行热输入,其与焊接残余应力线性正相关,焊前预热温度通过与焊接电压、焊接电流之间的交互作用会对焊接残余应力产生一定的影响。
Abstract:
In this article, it selected 12Cr1MoV heterogenic joint as experimental material, studied the coupling relationship among 3 main welding parameters, including welding voltage, welding current and pre-heating temperature before welding. The instance analysis and simulation verification were carried out for welding process through experiments and finite element method. The results showed that the curve characteristics of welding residual stress distribution and simulation results are identical with each other; simulation area of welding residual stress is consistent with the results measured value; the welding voltage and welding current can be obtained at relatively concentrated heat input, it is the linear positive correlation with the welding residual stress. Before welding, the pre-heating temperature will have certain influence on welding residual stress through the interaction between welding voltage and welding current.
