在金属材料的切割、焊缝清根和焊接坡口加工中广泛应用的碳弧气刨工艺,存在粉尘大、有气味、产生渗碳等缺点。为改善这一状况,采用了水碳弧气刨工艺。水碳弧气刨的原理,与碳弧气刨基本相似,只是压缩空气中含有大量水雾。水碳弧气刨枪,可用废旧的射吸式气焊枪改制:将原气焊咀和连接气焊咀的弯管切除,焊上碳弧气刨咀原乙炔入口改为压缩气入口,原氧气入口改为水入口。压缩空气与水在混合室混合后,即从气刨枪咀喷出饱含水雾的强力气流,水雾中水量的多少,可用针阀控制;为使
In the cutting of metal materials, weld roots and welding groove processing widely used carbon arc gouging process, there is dust, odor, carburizing and other shortcomings. To improve this situation, a carbon arc gouging process was used. Water carbon arc gouging principle, and carbon arc gouging basically the same, but the compressed air contains a large number of water mist. Water carburizing gas gouging gun, can be used to waste gas suction gun restructuring: the original gas welding nozzle and connecting the elbow cut off the gas welding, carbon arc welding gas welding original acetylene inlet into the compressed gas inlet, the original oxygen inlet to change For the water inlet. Compressed air and water mixed in the mixing chamber, that is, from the gas gun nozzle spray powerful air full of water, the amount of water in the mist can be needle valve control; to make
