VERFAHREN ZUR ABDICHTUNG VON HOCHDRUCKBEHÄLTERN UNTER VERWENDUNG VON MAGNETISCHER IMPULSGEBUNG MIT HOHER RADIALAUFPRALLGESCHWINDIGKEIT

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.
