摘要

为优化X80管线钢MIG焊的工艺参数

对MIG焊过程中的电弧电压、焊接电流、焊接速度、坡口间隙四个工艺参数进行了正交试验

以焊接接头应力峰值为评价指标

使用极差分析方法

获得了最优的工艺参数.借助ANSYS软件对最优的工艺参数进行模拟计算

得到了应力峰值在接头处的分布情况.结果表明:极差分析法能有效获得最优工艺参数

且焊接速度是接头处应力峰值的主要影响因素

其次为电弧电压、焊接电流、坡口间隙.研究结果为优化X80管线钢焊接工艺、有效减小焊后应力峰值提供了参考.

Abstract

In order to optimize the process parameters of MIG welding of X80 pipeline steel

four process parameters of arc voltage

welding current

welding speed and groove clearance in MIG welding process were carried out orthogonal test. Taking the peak stress of welded joint as the evaluation index

the optimum process parameters were obtained by using the range analysis method. With the help of ANSYS software

the distribution of welding stress at the joint was obtained by numerical simulation of the optimal process parameters. The results show that the range analysis method can effectively obtain the optimal process parameters

and the welding speed is the main factor affecting the peak stress at the joint

followed by arc voltage

welding current and groove clearance.The results provide the guidance for optimizing the welding process of X80 pipeline steel and reducing the welding residual stress effectively.
