Tracking experiment of MIG on V shapewelding groove is made with this method, and the experiment result validates the validity of this method.
利用该方法对V形坡口进行了金属熔化极气体保护电弧焊的跟踪试验，试验结果验证了所用方法的有效性。

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。

In addition, the choice of the weld shape strongly affects the welding process and the manufacturing costs.
