Abstract
A sheet of work-hardenable, non-heat-treatable, corrosion-resistant steel is cold rolled into a tube (12) and welded (10). The cold rolling strengthens the material. The welding causes the weld area (10) to revert to its annealed condition, but the ends (24, 30) of the tube (12) are then swaged into open domes (14, 16) to form a symmetrically-swaged tube having further work-hardened ends which overcome the apparent weakness of the weld (10). A spherical disk (20) is then welded on to one end to form a bottom and a port section (26) is welded on to the other end to complete the bottle construction.
