Abstract: A pulsed magnetic method of sealing a vessel (20) is provided. The method includes providing a vessel's body (21) having at least one open end, providing a cover (23) having a welding part (24). The welding part (24) of the cover (25) is placed over the open end of the vessel' s body (21) to overlap at least a portion of the vessel's body (21), thereby to define an air gap (26) between the portion of the vessel's body (21) and the welding part (24) of the cover (23). A welding induction coil (22) is provided around the vessel's body (21) at least at the place where the welding part (24) of the cover (25) is located. The welding induction coil (22) is energized to generate a pulsed magnetic force sufficient to cause bending the welding part (24) of the cover (21) in the air gap (26) in a radially inward direction around the portion of the vessel's body (21). The pulsed magnetic force has such a value so as to provide an effective radial velocity value of the cover's welding part (24) in the range of 150m/sec to 600m/sec at the moment of impact with the vessel's body (21), thereby to provide mutual diffusion of atoms of the vessel's body (21) and the cover (23) at their impact.
