Research progress and application of magnetically impelled arc butt welding technology in tubes welding

介绍了磁控旋转电弧焊的工艺特点和原理,综述了目前磁控旋转电弧焊在焊接工艺试验、焊接性能测试、焊接质量评价和焊接过程仿真的研究进展及其应用。研究结果表明,磁控旋转电弧焊焊接参数较多,参数之间存在相互影响;不同材料厚度、实心或空心都会对磁通密度产生影响,改变电弧速度进而影响焊接质量;磁控旋转电弧焊受磁通密度的影响较大,只适用于磁性材料的焊接,在非磁性材料应用几乎没有。最后展望了磁控旋转电弧焊未来的研究和发展方向。

The technological characteristics and principle of magnetically impelled arc butt welding were introduced.The research progress and application of magnetically impelled arc butt welding were reviewed on welding procedure test,welding performance test,welding quality evaluation and welding process simulation.The research result showed that there are many welding parameters in magnetically impelled arc butt welding,and the parameters affected each other.Different material thickness,solid or hollow would influence magnetic flux density,change arc velocity,and then affect welding quality.The magnetic flux density had a great influence on magnetically impelled arc butt welding,and it was only suitable for welding of magnetic materials,but hardly used in non-magnetic materials.Finally,the future research and development direction of magnetically impelled arc butt welding were prospected.
