| 摘 要： | 基于高速摄像的研究手段,对纵向磁场控制下的MAG焊旋转射流过渡过程的稳定性以及焊接工艺性等方面进行试验研究。结果表明,外加纵向磁场可以有效控制MAG焊接的旋转射流过渡过程,在送丝速度为45 m/min、保护气体为80%(体积分数)Ar+20%(体积分数)CO2时,可得到稳定性好、可控性好的旋转射流过渡,大大提高焊接生产效率。

| Abstract: | Based on high-speed photography, experimental study on the stability of rotating transfer and welding process under the control of longitudinal magnetic field is discussed. And the results show that the process of rotating transfer can be controlled by the additional longitudinal magnetic field. Under the shielding gas of 80% Ar＋ 200/40 CO2, a stable and better controlled rotating transfer is realized with the wire feed speed of 45 m/min. Thus the melting efficiency of the welding materials increases obviously. |
