苏联乌克兰科学院电液压设计室对用电液压脉冲处理来降低金属构件焊接接头的残余应力的可能性进行了研究,认为这种方法处理简便,效果好,效率高,电能消耗较少,能实现机械化自动化,是一种具有发展前途的方法。电液压脉冲处理的原理是电液压效应,是几万个大气压的冲击波、高速液流、强大脉冲产生的气穴现象、几百个大气压的次声及超声
The research on the possibility of reducing the residual stress of the welded joints of metal components by electro-hydraulic pulse processing was conducted in the Electro-hydraulic Design Office of the Ukrainian Academy of Sciences in the Soviet Union. The method is simple and easy to handle with high efficiency, low power consumption and mechanization Automation is a promising method. Electro-hydraulic pulse processing principle is the electro-hydraulic effect, tens of thousands of atmospheric pressure shock waves, high-speed flow, strong cavitation cavitation phenomenon, hundreds of atmospheric pressure infrasound and ultrasound
