It showed that the weld cross section with both laser welding processes transformed from nail shape to near X shape with increase of laser power and decrease of welding speed.
结果表明，随激光功率增大和焊接速度降低，复合焊与单一激光焊焊缝的横截面形貌均由钉形向近X形转变。

Then use the coil ring machine rolled into a circle, with the electrode to weld the interface firmly, welding mouth to carry out X spectroscopy.
然后用卷环机卷制成圆圈，用焊条把接口处焊接牢固，焊口处要进行X光谱检验。

With increase of heat input and laser power density, the cross section of the weld transformed from nail shape to near X shape.
