摘　　要：药芯割丝电弧切割是一种高效优质的水下切割方法,目前该方法对铝合金材料切割的研究较少,为此开展了相关工艺研究。利用能模拟不同水深的切割装置,附加霍尔电流、电压传感实现对切割过程的数据采集;设计试验时,考虑水下切割工艺范围较窄,在保持其他工艺参数不变的情况下考察某一参数变化对切割过程的影响;通过观察割口、分析数据等方式研究水深、电流、电压等主要工艺参数。结果表明,5052铝合金切割时主要参数的影响与低碳钢类似。但由于铝热反应使其切割过程更容易进行,过程更剧烈。此外异种金属切割使得割口中的残渣容易去除,其所需的热输入相比碳钢更低。Flux-cored wire arc cutting is an efficient and high quality underwater cutting method. The cutting procedure of aluminum alloy based on this metllod was rarely studied,so relative research was done in this paper. Firstly,a cutting device was used to simulate different water depth,and relative hall current and voltage sensor was used to acquire data during cutting process. Secondly, the influence of one parameter on cutting quality was studied with other parameters being constant because of the narrow cutting parameter range. Finally, the effect of water depth, current and voltage on cutting process were researched by observing the cutting edge. The result showed that the influence of main parameters on stainless steel cutting process was similar with that of low carbon steel cutting. Due to the thermite reaction,the cutting was easier and more violent than that of low carbon steel. In addition,dissimilar metal cutting made the remainder in cutting area easier to remove ,so the heat input could be properly reduced.
