磁控焊接技术的研究现状
|
摘要
介绍了磁控焊接技术的基本原理及装置,并从其对电弧形态、熔滴过渡形式、熔池内液态金属温度场及流动状态等的影响进行了阐述。与普通的焊接技术相比,磁控焊接技术将磁场产生的磁场力引入到焊接过程中并对其进行干涉,通过调节磁场的方向和大小能够改善焊缝成形、改变接头组织及提高力学性能等。因此开展磁控焊接技术的研究具有很高的工程实用价值。
The basic principle and equipment of magnetic controlled welding technology are introduced,and its influence on arc shape,droplet transfer mode,liquid metal temperature field and flow state in weld pool during welding are expounded. Compared with ordinary welding technology,magnetic controlled welding technology introduces magnetic field force generated by magnetic field into welding process and interferes with it. By adjusting the direction of magnetic field and its strength,so it can improve the weld formation,change the microstructure of weld metal and improve mechanical properties. Therefore,the research on magnetic controlled welding technology has high practical engineering value.
