Tests were made on a high-speed side-seam welder. Its maximum speed was 50 m/min at a current frequency of 500 Hz. Cans of various diameters ranging from 52 to 99 mm were produced from thin-gauge steels. The type of annealing, the temper rolling reduction rate, the hardness and the surface coating were varied. The intention was to investigate the rounding behaviour of the body blank, the welding and the flanging behaviour of the can body. The inside lacquer coating was applied by different processes to welded cans, which were then subjected to storage tests. It was found that the normal procedure - lacquered body blanks used for making the cans and the welded side seams covered with a protective coating - could only be used with organosol lacquers. If the lacquer spray coating process was applied after beading of the cans, both organosol and epoxy lacquers were satisfactory.
