针对典型的马鞍形焊缝进行数学建模，并利用MA TLAB软件计算焊接位姿参数。
The mathematical model of typical saddle-shape weld was established, and the welding pose parameters were calculated with MATLAB.
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。
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.
