Research on Arc Cutting Technology in Seawater Environment
Aiming at the problems of large electrode loss or poor seam quality in existing thermal cutting methods,a rod-shaped electrode cutting method using in seawater environment was proposed according to the principle of high-speed arc discharge machining.High-energy arc plasma was used to thermally corrode the workpiece,and the corroded particles in the cutting process were discharged through the action of high-speed fluid between electrodes.It can achieve high efficiency and low cost underwater cutting,and obtain neat slit,less slag hanging phenomenon and no bridge phenomenon.Tungsten electrode is used to cut 10 mm thick stainless steel plate.The influence of pulse width,pulse interpulse and flush pressure on feed speed,slit width and electrode loss is analyzed.The results show that the efficient cutting process in seawater environment can be realized by selecting suitable machining parameters.
