Zusammenfassung:PROBLEM TO BE SOLVED: To provide a welded boiler drum in which a welded part is not conspicuous, and excellent appearance can be obtained. SOLUTION: A cylindrical welded boiler drum 1 is formed by welding end parts 1a, 1b of a metallic boiler drum blank.

A welded part 2 is covered by the synthetic resin film 4 to overlap the end parts 4a, 4b at the prescribed position of the outer surface of the boiler drum.
