Abstract
Abstract An end portion of a first tubular member is inserted within the end portion of a second tubular member and a die means is disposed in surrounding relation to said second tubular member. Explosive means is disposed adjacent to said die means, and the components are confined within a closed chamber. Detonation of explosive means moves the die means along the second tubular member to cold-forge the second tubular member to the first tubular member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
78 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an enlarged end portion of said second tubular member, said end portions of the tubular members being cold-forged together through both a radially inward swaging and a longitudinal extrusion of said second tubular member, developed by die members driven explosively along the outer surface thereof, over the outer surface of said first tubular member.
Claim 2
Dependent Claim
78 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an enlarged end portion of said second tubular member, said end portions of the tubular members being cold-forged together through both a radially inward swaging and a longitudinal extrusion of said second tubular member, developed by die members driven explosively along the outer surface thereof, over the outer surface of said first tubular member.
Claim 3
Dependent Claim
35 words
Apparatus as defined in claim 1 wherein the inner surface of a non-enlarged portion of said second tubular member is of substantially the same inner dimension as the inner surface of said first tubular member.
Claim 4
Dependent Claim
93 words
Apparatus as defined in claim 1 including a third tubular member, an end portion of said third tubular member being disposed within the opposite and also enlarged end portion of said second tubular member, the contacting end portions of said third tubular member and said second tubular member also being cold-forged together due to a radially inward swaging and a longitudinal extrusion of said opposite end portion of said second tubular member, developed by further die members driven explosively along the outer surface thereof, over the outer surfaces of said second tubular member.
Claim 5
Dependent Claim
106 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an end portion of said second tubular member, said end portions of the tubular members being cold-forged together through a longitudinal extrusion and also through a radially inward swaging of said second tubular member developed by die members driven along the outer surface thereof by a force generated by the burning of a propellant charge, the outer surface of said first tubular member and a portion of the outer surface of said second tubular member being of substantially the same outer dimension.
Claim 6
Dependent Claim
106 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an end portion of said second tubular member, said end portions of the tubular members being cold-forged together through a longitudinal extrusion and also through a radially inward swaging of said second tubular member developed by die members driven along the outer surface thereof by a force generated by the burning of a propellant charge, the outer surface of said first tubular member and a portion of the outer surface of said second tubular member being of substantially the same outer dimension.
Claim 7
Dependent Claim
98 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an end portion of said second tubular member, said first and said second tubular members having said end portions cold-forged together through a longitudinal extrusion and also through a radially inward swaging of said second tubular member developed by die members driven explosively along the outer surface thereof, the outer surface of said first tubular member and a portion of the outer surface of said second tubular member having substantially the same outer dimension.
Claim 8
Dependent Claim
98 words
A tubular connection comprising a first tubular member and a second tubular member, an end portion of said first tubular member being disposed within an end portion of said second tubular member, said first and said second tubular members having said end portions cold-forged together through a longitudinal extrusion and also through a radially inward swaging of said second tubular member developed by die members driven explosively along the outer surface thereof, the outer surface of said first tubular member and a portion of the outer surface of said second tubular member having substantially the same outer dimension.
Claim 9
Dependent Claim
174 words
A tubular connection comprising a first elongated tubular member of a predetermined constant outer diameter, a second elongated tubular member also of the same predetermined constant outer diameter, and a tubular coupling member having a central portion of a given inner diameter and two opposed end portions of an inner diameter larger than said center portion, an end portion of said first tubular member being disposed within one of the end portions of said tubular coupling member and an end portion of said second tubular member being disposed within the other end portion of said tubular coupling member, said first and said second tubular members having said end portions cold-forged to the respective end portions of said tubular coupling member through a longitudinal extrusion and also through a radially inward swaging of the said end portions of said tubular coupling member developed by die members driven explosively along the outer surFace thereof, and the outer diameter of the central portion of said tubular coupling member being substantially equal to said predetermined constant outer diameter.
Claim 10
Dependent Claim
174 words
A tubular connection comprising a first elongated tubular member of a predetermined constant outer diameter, a second elongated tubular member also of the same predetermined constant outer diameter, and a tubular coupling member having a central portion of a given inner diameter and two opposed end portions of an inner diameter larger than said center portion, an end portion of said first tubular member being disposed within one of the end portions of said tubular coupling member and an end portion of said second tubular member being disposed within the other end portion of said tubular coupling member, said first and said second tubular members having said end portions cold-forged to the respective end portions of said tubular coupling member through a longitudinal extrusion and also through a radially inward swaging of the said end portions of said tubular coupling member developed by die members driven explosively along the outer surFace thereof, and the outer diameter of the central portion of said tubular coupling member being substantially equal to said predetermined constant outer diameter.
