How to finish the grinding process after the completion of the box welding to ensure the surface smoothness
Processing method is used with emery cloth wheel polishing grinder, grinding surface to reach and no bulge as smooth, so that it is not in the spray after local anomalies and in welding to adjust the welding parameters in welding firmly under the premise to reduce welding deformation and bulging.
By the way, the welder used for welding is carbon dioxide gas shielded welding machine. Compared with the ordinary electric welding machine, the bulging and hot deformation are much smaller.
When grinding, we use a corner grinder to grind it slightly, and the amount of polishing is not large. In addition, it is better to spray the thickness of the coating in the parts of the grind when it is sprayed.
