TANK MANUFACTURING METHOD, MIRROR PLATE OF TANK, AND TANK

In a tank (1) including a body (10) and an end plate (20) that are joined together by welding, an end portion (21) of the end plate (20) has a concave portion (31), and a protrusion (32) protruding outward beyond the body (10). An abutting step of making the end portion (21) of the end plate (20) an...

Beschreibung
Zusammenfassung:	In a tank (1) including a body (10) and an end plate (20) that are joined together by welding, an end portion (21) of the end plate (20) has a concave portion (31), and a protrusion (32) protruding outward beyond the body (10). An abutting step of making the end portion (21) of the end plate (20) and an end portion (11) of the body (10) abut against each other, and a joining step of welding portions of the end plate (20) and the body (10) abutting against each other together are sequentially performed to manufacture the tank (1). This reduces corrosion and stress concentration caused by clearance in the tank (1), and allows the end plate (20) and the body (10) to be welded together in their correct relative positions.
