Abstract: A butt welding system and a butt welding method of steel plate by which the quality of a product can be ensured. Butting portions of blank members (1,2) to be joined together are butted and a predetermined butting load is applied to the butting portion, wherein the blank members (1,2) are moved relatively in the direction of the welding line thus matching the butting portions. Protrusions and recesses formed on each butting portion of each blank member (1,2) are flattened, whereby linear precision at each butting portion of each blank member (1,2) is enhanced as compared with a case where the butting portions are not matched. Since the gap is reduced extremely at the butting portion, welding is facilitated at the butting portion. Good welding beads are thereby obtained at the butting portion and the quality of a product is ensured.
