A method of producing an hermetically sealed bond between a first metal and a second metal wherein the first metal comprises a first portion and a second portion , the method comprising (a) positioning the second portion and the second metal in generally spaced apart parallel relation; and (b) propelling the first portion into collision with the second metal so as to produce the hermetically sealed bond between the first portio n and the second metal. The propulsion is preferably effected by a high velocity explosive charge of 5,500 - 9,000 m/s. The improved resultant bond is hermetically sealed. Th e process is of value in providing an hermetically sealed chamber, cavity or envelope having improved sealed properties.
