在大量工艺实验的基础上，研究了钛合金激光填丝焊接中影响焊接过程稳定性的主要因素和影响焊缝成形的主要工艺参数，获得了一定条件下送丝速度与焊接速度的合理匹配范围。研究结果表明，熔滴过渡方式和离焦量是影响焊接过程稳定性的主要因素，送丝速度和焊接速度是影响焊缝成形的主要工艺参数，为了获得良好的焊缝成形，送丝速度与焊接速度必须合理匹配。

The factors influencing the welding stability and the procedure parameters affecting the weld shaping in laser welding with filler wire of titanium alloy are investigated experimentally, and the reasonable matching sketch between wire feeding rate and welding speed is obtained. It shows that the melting dropt transition and the focus position have significant influences on laser welding stability, while the procedure parameters such as wire feeding rate and welding speed have important effects on weld shaping. In order to obtain the weld shaping with good quality, it is necessary that wire feeding rate must reasonably match with welding speed.
