ABSTRACT:
A liquid storage tank can be manufactured with improved efficiency and greater strength by creating bent sheets to form the sides and bottom portions of the tank. The interior corner of the bend is reinforced by an extrusion weld. Two or more of the side/bottom bent sections are then butt jointed together to form a rectangular, t-shaped, or other shaped tank. The tank is completed by two end pieces extrusion welded to the bent side/bottom pieces and a lid extrusion welded to the sides.
