Plasma arc cutting is a process method that uses plasma arcs with temperatures up to 15000~30000CC for cutting. The basic principle is: using high temperature and high speed plasma arc as the heat source to melt the part to be cut, and using the mechanical scouring force of compressed Jet stream to blow away the melted metal or non-metal to form a narrow incision. This new process method can not only cut ordinary materials, but also cut difficult to machine materials.
The characteristics of plasma arc cutting: it can cut any black and non-ferrous metals as well as various non-metallic materials; Fast cutting speed and high productivity; High cutting quality.
Plasma arc cutting technology
The process parameters of plasma arc cutting include cutting current, arc voltage, cutting speed, type and flow of working gas: quantity, nozzle aperture, tungsten electrode shrinkage, distance from nozzle to cutting piece, etc.
The selection method of process parameters: Firstly, select the appropriate power based on the thickness of the cutting piece and material properties, and select the cutting current and working voltage according to the power; Then select the nozzle aperture and electrode diameter, and finally select the appropriate gas flow rate and cutting speed.
