EXPLOSIVE BONDING OF TUBES TO FITTINGS

摘要

A method of explosively joining tubes to fittings by first inserting the tube into a double tapered hole bored in the fitting and then positioning a close fitting wooden dowel having a charge of sheet explosive wrapped therearound in the tube under the tapered area. The double tapered cavity between the outer wall of the tube and the fitting is then evacuated by withdrawing the air therefrom and the explosive is detonated causing the tube to expand radially outward against the wall of the double tapered cavity producing a high integrity bond between the tube and the fitting.
