摘要

使用摆动光束对 TC11 钛合金进行激光焊接。研究了不同参数下焊缝的气孔率、微观结构和机械性能。研究发现，提高振荡频率可有效抑制气孔。当振幅小于或等于 1 毫米、激光功率约为 3 千瓦、焊接速度小于 15 毫米/秒时，气孔可以得到有效抑制。振荡频率和振幅都能增加α′相的数量。振荡频率可促进柱状晶中α′相和α″相的交叉分布。振荡振幅可促进α′相在柱状晶中的均匀分布。提高振荡频率和振荡幅度有利于提高抗拉强度。在缺陷率较低的情况下，焊缝的抗拉强度可达母材的 90% 以上，最大伸长率为 7.5%。

Effects of beam oscillation on porosity and microstructure of laser welded TC11 titanium alloy

Oscillating beam was used for laser welding of TC11 titanium alloys. The porosity, microstructure, and mechanical properties of welds with different parameters were studied. It was found that increasing the oscillation frequency could effectively suppress porosity. When the oscillation amplitude was less than or equal to 1 mm, the laser power was about 3 kW, and the welding speed was less than 15 mm/s, porosity could be effectively suppressed. Both oscillation frequency and amplitude could increase the number of α′-phase. The oscillation frequency promoted the cross distribution of α′-phase and α″-phase in the columnar crystal. The oscillation amplitude promotes the uniform distribution of α′-phase in the columnar crystal. Increasing the oscillation frequency and the oscillation amplitude was beneficial to increase the tensile strength. In the case of low defect rates, the tensile strength of the weld could reach more than 90% of the base metal, and the maximum elongation was 7.5%.
