Explosive bonding device

Claim 2

An explosive bonding device for bonding together disjointed metal pieces for the conduction of electricity comprising a. one or more metal bonding strips; b. one or more electrical conductors attached to each of said metal bonding strips; c. one or more spacing means attached to the bonding surface portion of each of the bonding strips; d. at least one explosive charge means attached to each of the bonding strips on the opposite side of said bonding surface; and e. one or more explosive detonating means connected to each of said charges.

Claim 3

An explosive bonding device as in claim 1 comprising: a. two or more separate bonding strips interconnected by an electrical conducting means; b. two or more spacing means attached to each bonding surface of said bonding strip; c. at least one charge means for each bonding surface and; d. an explosive charge detonating means connected to each charge.

Claim 4

An explosive bonding device as in claim 2 wherein a. the bonding strips are prepared from metals selected from the group consisting essentially of copper, copper alloys, aluminum, steel and stainless steel having a thickness of from 0.015 to 0.375 inches; b. the bonding strips are electrically interconnected by copper cable; c. the spacing means maintain the bonding surfaces a distance of at least 25 to 150 percent of the thickness of the bonding strip apart from the surface to be bonded; d. the explosive charge is an explosive having a detonation velocity of at least 6,000 to 18,000 ft./sec.; and e. the detonating means is selected from the group consisting of detonating cord, electrical blasting caps and fuse blasting caps.

Claim 5

A bonding device as in claim 3 wherein a. the bonding strips are annealed copper strips having a thickness of from 0.060 to 0.080 inch. b. the explosive charge is packed to a density of from 4 to 30 gms/cu. inch in charge containers permanently affixed to said bonding strips; c. the bonding surface is covered with a protective means; and e. the spacing means are substantially the same size.

Claim 6

A bonding device as in claim 4 wherein a. the spacing means are from 25 to 80 percent of the bonding strip thickness; b. the explosive charge is packed to a density of 10 to 15 gms/cu inch per square inch of bonding surface; and c. the explosive charge is an explosive having a detonation velocity of at least 6,000 to 10,000 ft./sec.
