2. Description of the Related Art Generally, when manufacturing a box-type structural material, welding slag due to submerged arc welding adheres to the surface of a structural material side plate immediately after welding. Therefore, it is necessary to remove the welding slag, but conventionally, the welding slag has been removed by peeling off with a chisel.

[0003]

However, since this work is carried out at a fairly high temperature immediately after welding, it has been forced to work under extremely bad conditions, especially during the hot summer months. Further, the work requires at least two workers, one who operates the welding apparatus and the other who removes the welding slag, and since the welding and the welding slag removal work are performed before and after, the productivity is improved. It was extremely bad.

Further, since the labor cost and the production cost increase, it has been desired to improve the production efficiency by automation and reduce the production cost.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and an automatic welding slag recovery apparatus which can improve the productivity and reduce the production cost by automatically recovering the welding slag. The purpose is to provide.
