The influence of laser power, scanning speed, powder feed rate, spot diameter and preheating on the temperature of molten pool were revealed in the process of single-pass cladding.

在单道熔覆中通过跟踪测量研究了激光功率、扫描速度、送粉速率、光斑直径和基体预热温度对熔池温度的影响规律。

Based on the model, the morphology with the growth direction same with scanning direction was obtained at the top of the melting pool through the match among the processing parameters.

据此通过工艺参数的匹配，在熔池顶部得到了与扫描方向完全一致的凝固组织。
