摘要： An electromagnetic forming apparatus for forming an essentially planar metal plate into a dish having a three-dimensional pattern, is provided. The apparatus comprises a mould having a forming surface with a contour corresponding to said three-dimensional pattern; a forming coil device; and an electric discharge circuitry for discharging a short and intense electric current pulse through the forming coil device to yield a pulsed magnetic forming (PMF) force for deforming said plate.

摘要： Two workpieces are joined together or welded to one another by inducing movement in a first of the two workpieces or a portion thereof by means of a pulsed magnetic force, whereby the first workpiece or portion impacts onto the second of the two workpieces and the two then become joined or welded to one another.

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

摘要： A pulsated magnetic welding method and a welding induction coil for sealing a vessel (10) are provided. The method includes providing a vessel's body (11) having an open end (12) a cover (13) including a welding part and a brim par t (15). A diameter of the cover (13) at the welding part (14) is less than the diameter of the vessel's body (11) for providing an air gap (16) between the vessel's body (11) and the welding part (14). The cover (13) is placed withi n said open end (12) of the vessel's body (11). A welding induction coil (18) is provided around the vessel's body (11) at the place where the welding part (14) of the cover (13) is located. The welding induction coil (18) is energized to generate a pulsed magnetic force sufficient to cause bending a portion (19) of the vessel's body (11) in a radially inward direction around the cover (13) in the air gap (16). The pulsed magnetic force has such a val ue so to provide mutual diffusion of atoms of the vessel's body (11) and the cover (13) at their impact, thereby to weld the vessel's body (11) and the cover (13) to each other.
