| 摘 要： | 在传统双电极角焊焊接工艺基础上,为了进一步提高焊接效率,采用三电极高速CO2双边角焊工艺,分析不同焊接工艺参数对焊缝成形参数的影响.结果表明,采用不同极性组合的焊缝成形参数差别不大;随着速度的减慢和焊接工艺参数的增大,脚长、熔深和熔宽均呈增大趋势,但焊脚长度有一个最大值限制.下脚长、上脚长受中间焊枪的指向位置影响更为明显,当左右两侧焊枪对中时,脚长最小.另外,随着焊丝之间距离的增大,脚长和熔宽逐渐减小,余高随焊丝距离增大而增大,但差别不大.

| Abstract: | In order to improve the welding efficiency, tripleelectrode high-speed CO2 fillet welding process was adopted based on the twin-electrode CO2 welding, and the effect of welding conditions on weld geometry parameters was analyzed.The results show that weld geometry parameters are more or less the same by DCEP/DCEN/DCEP and DCEN/DCEP/DCEN polarities.Leg length, penetration and weld width increase with the speed slowdown and welding combination parameters increase, but leg length has a maximum limit.Middle-electrode offset plays an important role in welding geometry parameters, and the leg length is the smallest when the electrodes shift from one side to the other side is ±30mm in this experiments.In addition, the leg length and weld width gradually decrease with increasing the distance of wire to wire. |
