Method of magnetic impulse welding of sheets, one of the sheets having at least one attachment region inclined at an angle to the sheet plane

摘要

A first sheet (2) comprises at least one attachment region (4) inclined at an angle to a sheet plane (15). The first sheet (2) is arranged on a second sheet (3) so that the attachment region (4) of the first sheet (2) is spaced at a distance from the second sheet (3). A magnetic field pulse is applied so as to cause a force on the attachment region (4) in directions generally perpendicular to the first sheet plane (15) and the second sheet plane (16) so that the attachment region (4) of the first sheet (2) is driven against the second sheet (3) with sufficient force to produce a cold-welded joint between the attachment region (4) of the first sheet (2) and the second sheet (3).
