Welded cans
 A tinned steel sheet having a tin deposit obtained by evenly plating tin on the surface of a base steel sheet at a deposition rate of 0.5-1.7 g/m.sup.2 is used as a surface-treated steel sheet for forming a can body. A biaxially oriented polyester film having a thickness of 5-50 .mu.m is caused to adhere to the surface-treated steel sheet with a thermosetting resin adhesive at a temperature of 180.degree.-225.degree. C. as a protective coat. The tinned steel sheet has, on its both ends, two layers of a tin-iron alloy layer having a deposition rate of 0.35-1.60 g/m.sup.2 in terms of tin content and a tin layer having a tin deposition rate of 0.10-1.35 g/m.sup.2 at a stage after the adhesion of the polyester film but before welding. Said both ends of the surface-treated steel sheet are welded to each other, and another protective coat is applied to a portion of the inner surface, which is not covered with the first-mentioned protective coat, thereby forming a welded can.
