| 摘 要： | 用高速摄像系统和电流电压采集模块对带状电极MAG焊工艺电弧行为进行了研究.结果表明,带状电极MAG焊电弧呈非柱对称分布,电弧截面从钢带端部到母材逐渐由椭圆形过渡到圆形.随焊接工艺参数的增大,电弧能量提高,钢带端部由多个电弧共存转变为一个电弧燃烧,电弧沿钢带无规律的紊乱运动转变为较稳定的左右摆动,进而转变为不发生明显摆动...

| Abstract: | The arc behavior of MAG welding with strip electrode was investigated using a high speed CCD camera system and a current and voltage acquisition set.The results show the welding arc is not cylindrical symmetry,it has a pronounced elliptical shape at the strip electrode end,and tends to be more circular whereas at the workpiece.There are several arcs generated simultaneously at the strip electrode end with low current,and they move along the strip electrode with no regularity.With the increase of welding cur... |
