摘要
采用气胀成形方法对TA15钛合金四层结构芯板加强结构的激光焊接(LBW)/超塑成形(SPF)技术进行了研究。结果表明,满足超塑成形的最佳激光穿透焊接工艺参数为:功率2300W,焊接速率0.8m·min-1,离焦量+1;最佳超塑成形参数为:成形温度930℃,成形压力2.0MPa,成形时间60min;芯板加强结构成形效果良好。
The laser beam welding/superplas- tic forming technology of TA15 titanium alloy strengthen core board in four layers structure by inflatable forming method is studied. The most appropriate parameters of laser beam welding process for superplastic forming are that power 2300W, welding speed 0.8m·min^-1 and the de- focusing amount ＋1. The most appropriate parameters of superplastic forming are that temperature 930℃, forming pressure 2.0MPa and forming time 60 min. The forming effect of the strengthen board is good.
