摘　　要：熔化极药芯割丝电弧切割是一种高效优质的水下切割方法,采用该方法切割不锈钢材料的研究较少。本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;实验设计时,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;通过观察割口研究水深、电流、电压等主要工艺参数。结果表明,不锈钢切割时,主要工艺参数的影响与低碳钢切割时类似,但由于不锈钢的导热性较低以及异种金属切割时割缝中残渣更容易去除,切割时可以适当降低热输入。Flux-cored wire arc cutting is an efficient and high quality underwater cutting method. The cutting procedure of stainless steel based on this method was rarely studied,so relative research was done in this paper. Firstly,a pressure vessel with welding device was used to simulate different water depth,and relative hall current and voltage sensor was used to acquire data during cuning 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 pressure,current and voltage on cuning process were researched by observing the cutting edge. 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 low thermal conductivity,and easy removing of residue in dissimilar metal cutting,the heat input could be reduced during stainless cutting process.
