    摘要
  • 摘要: 以ABAQUS软件为平台,开发热-弹-塑性有限元方法模拟了V形坡口和K形坡口Q345/SUS304异种钢多层焊对接接头的温度场、残余应力和焊接变形.同时采用试验的方法测量了接头的残余应力和角变形.计算结果与试验测量结果吻合良好,验证了计算方法的妥当性.数值结果表明,不同坡口Q345/SUS304异种钢接头的Q345母材与焊缝交界处的应力分布均出现不连续性,且SUS304侧的高拉伸残余应力区明显宽于Q345侧;K形坡口开口朝向Q345侧相较于开口朝向SUS304侧的接头,Q345/焊缝交界处附近的峰值应力和高拉伸残余应力区均明显较小.试验和数值结果表明,坡口形式对接头的角变形有明显的影响.
    Abstract: Based on ABAQUS software, a computational approach was developed to simulate welding temperature field, residual stress distribution and deformation for Q345/SUS304 dissimilar steel multi-pass joint into groove shape of V and K type with 10 mm thickness. Meanwhile, experiments were carried out to measure welding residual stresses and angular distortion in the butt weld. Through comparing the simulated results with the measured data, we found that both residual stresses and angular distortion predicted by the numerical model were in good agreement with the experimental measurements. The simulation results show that the longitudinal residual stress distribution is discontinuous near the fusion line between Q345 and weld metal, and the region with high tensile stress in SUS304 side is wider than that in Q345 side. Comparing K groove welded joints of opening toward the Q345 side with opening toward the SUS304 side, the peak value of residual stress and the high tensile residual stresses near the intersection area of the Q345/weld were significantly smaller. The experimental and simulation results show that groove shape has prominent influence on angular distortion.
