7.碳极空气等离子弧堆焊机该机采用碳棒作电极,压缩空气为等离子弧工作气体,使用特殊的等离子弧焊枪,堆焊自熔性耐磨合金。合金过渡系数不低于氩气等离子弧堆焊;气体和电极消耗比氩气等离子弧堆焊的成本降低90％。这种方法主要用于金属表面耐磨强化。堆焊机由一台堆焊机床、1～2把等离子弧焊枪,1～2台硅整流弧焊机、一个控制箱组成。其主要技术参数为:堆焊电流100～400A,堆焊宽度60mm,生产率0.025m~2/h,可堆焊面积1×2m~2。
7. Carbon air plasma arc welding machine The machine uses carbon rods as electrodes, compressed air for the plasma arc working gas, the use of special plasma arc welding gun, self-welding surfacing wear-resistant alloy. Alloy transition factor is not less than argon plasma arc welding; gas and electrode consumption than argon plasma arc welding costs reduced by 90%. This method is mainly used for metal surface wear-resistant. Overlay welding machine by a surfacing machine, 1 ~ 2 plasma arc torch, 1 ~ 2 silicon rectifier arc welding machine, a control box. The main technical parameters are: welding current 100 ~ 400A, welding width 60mm, productivity 0.025m ~ 2 / h, welding area can be 1 × 2m ~ 2.
