Abstract
A cylinder is closed to form a sealed container for gases and the like. The cylinder is closed by means of a pair of specially constructed end caps each having annular recesses formed around their circumference. The ends of the cylinders are engaged within the recess and joined by magnetic pulse forming. The magnetic pulse foxing force is asserted radially inward against a mandrel which mates with a depression formed in the caps so that the assembled cylinder and cap are squeezed into sealed relation.
