Influence of technological parameters on friction hydro pillar processing

基于摩擦焊技术特点,研究摩擦叠焊单元成形工艺,分析转速、进给速度和轴向压力这三个主要工艺参数对摩擦叠焊单元成形过程的影响。结果表明:焊接过程中选用高转速,可以显著提高产热速率,填充材料更容易达到塑性状态而与预制孔侧壁紧密结合,在与转速匹配较好的进给速度和轴向压力范围内,选用较高的进给速度和轴向压力更容易获得质量优异的接头。

Based on the characteristics of friction welding technology,the friction hydro pillar processing is studied,and the influence of three main technological parameters on the friction hydro pillar processing is analyzed. The results show that the rate of heat production can be significantly improved under the condition of high rotation speed in the welding process, and filling material can be processed more easily into the plastic state and integrated closely with side wall of pre-drilled hole. In the range of feed rate and axial pressure which better match with rotation speed ,the high quality joints can be acquired under high feed speed and high axial pressure.
