Abstract
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 portion 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. The process is of value in providing an hermetically sealed chamber, cavity or envelope having improved sealed properties.
Claims8
A method of producing an hermetically sealed envelope or chamber between a first metal and a second metal, said first metal comprising a first portion and a second portion, wherein said first portion has a surface defining a closed loop;
- said loop having a first substantially longitudinal surface and a second substantially longitudinal surface in spaced apart parallel relation to said first longitudinal surface;
- said loop formed with a first terminal portion and a second terminal portion in diametrically opposed relationship;
- said method comprising:
- (a) positioning said second portion and said second metal in spaced apart relation placing an explosive along the loop formed in the first portion to form a substantially identical explosive lop;
- (b) propelling said first portion into collision with said second metal so as to produce said hermetically sealed envelope or chamber between said first portion and said second metal comprising connecting a detonator to said first terminal portion of the explosive, and detonating said detonator at said first terminal portion, whereby said detonation travels said explosive loop, simultaneously along said first longitudinal surface and said second longitudinal surface to terminate in said second terminal portion.
