ARC-NZG7-1r roller press automatic repairing system
Two methods:one is automatic submerged arc overlaying by usingΦ1.2~4.0mm flux-cored or solid wire below the flux layer.Second one is open-arc overlaying by Φ1.2~3.2mm self-protective flux cored wire.
In the codition of open-arc welding,the protective flux and slag remover,saving labor,cut cost,less intensity of labor,improvd welding quality and the anti-wear performance.
Weld torch can move simplely after start the welidng torch oscillating device,weling seam can be adjust casually,the welding seam cooling speed can be controlled well,the hardness of the surface and the crack tendency can be improved.
