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。
With increase of heat input and laser power density, the cross section of the weld transformed from nail shape to near X shape.
随焊接热输入和激光功率密度的增大，焊缝截面由钉形向近X形转变。
Inferring from the flaw detection of X-ray, the sword possibly first forged the body by block casting iron, then cast the bronze handle, at last cast together to shape the sword.
从X射线探伤分析的情况推测，它很可能是先用块炼铁锻制刀身，之后再浇铸铜柄，而合铸成型的。
