Ti-3Al-2.5V钛合金是一种冷加工成形性优异的钛合金,广泛用于制造航空液压管路系统。虽然该合金具有很好的焊接性能,但采用传统的化学方法清理焊件污染层时受浸蚀液成分、温度及浸蚀时间变化易产生过浸蚀或欠浸蚀,因此进行了脉冲激光清洗焊管表面研究,并借助脉冲钨电极弧焊技术焊接管材接头。
Ti-3Al-2.5V titanium alloy is a cold forming workability of titanium alloy, widely used in the manufacture of aviation hydraulic piping system. Although the alloy has good welding performance, but when using conventional chemical methods to clean up the contamination layer of the weldment, the composition of the etching solution, the change of temperature and etching time are easy to cause over-etching or under-etching, so the pulse laser cleaning Welded pipe surface studies and welding of pipe joints with pulsed tungsten electrode arc welding.
