碳弧气刨的应用日趋广泛。目前,除了用来对封底焊缝进行抠槽外,还被逐渐推广到焊接坡口的加工和消除铸钢件缺陷等方面。几年来的实践证明,这种工艺方法,不仅生产效率高,切口质量好,更重要的是消除了手工风铲的噪音和振动,降低了劳动强度,从而从根本上避免了耳聋和骨骼变形对人体的威胁。碳弧气刨是利用碳棒与工件产生的电弧热量加热金属至熔点,并借压缩空气的吹力,吹除已熔化金属而完成其加工过程的。在气刨过程中生成的一氧化碳和金属粉尘,
The use of carbon arc gouging is becoming more widespread. At present, in addition to the back seam weld groove, but also has been gradually extended to the welding groove processing and elimination of castings defects and so on. Years of practice has proved that this method not only has the advantages of high production efficiency and good incision quality but also more importantly eliminates the noise and vibration of the manual wind shovel and reduces the labor intensity so as to fundamentally avoid deafness and skeletal deformation Human threat. Carbon arc gouging is the use of carbon rods and the workpiece arc heat generated by heating the metal to the melting point, and by the compressed air blowing, blowing off the molten metal to complete its processing. Carbon monoxide and metal dust generated during gouging,
