Description

Ship segment folding weld surface treatment device Technical Field The invention relates to the field of ship surface treatment, in particular to a ship segment folding weld surface treatment device. Background When the ship is built by sections, the sections are coated, but the welding seams between the sections are kept at a certain distance without coating, generally only the shop primer with weldability is coated, and after the sections are folded and welded, the welding seams and the surrounding welding seams are subjected to surface treatment. However, because the sectional welding area is narrow, the sand blasting can damage the nearby normal coating, and the polishing effect of the traditional polishing device on the sectional welding area is poor, a new ship sectional folding weld surface treatment device is required to be provided. Disclosure of Invention The invention aims to overcome the defects in the prior art, and provides the ship segment folding weld surface treatment device which has a good surface treatment effect on a segment welding area of a ship.
