It relates to a shot blast using.

The ship's construction is composed by welding several steel plates, and the construction of a single hull is used as a general method. Therefore, welding is an essential work process for building a ship and a work process having a large specific gravity. .

Therefore, in construction of ships, the construction of welding is fast and the connection of steel plate is used, but it is widely used, but it is used for welding surface by welding and the fire surface damage and impurities such as welding dregs due to welding residues. This was always dirty, and when inspecting the welded site, it was difficult to determine whether the weld was correctly welded.

When the welding work is finished, the surface is painted by the following work. Before the surface is painted, the preceding work is to clean and clean the welding line and the welded area, and the surface cleaning work is performed to facilitate the painting work that is performed later. This is to prevent the paint job from being smooth due to dust or impurities on the surface.

Surface cleaning work is performed by hand using grinder, sandpaper, and other abrasives to clean up dirty surfaces due to welding work. On the other hand, since the quality of the work for surface cleaning is not uniform, there is a problem that a lot of difficulties arise in the process of painting work that is carried out later.
