Abstract
A fixture for explosively welding a tube to a tubesheet in which a plug extends within a cup which in turn is inserted into a fixture tube. A first explosive extends within the chamber defined by the cup and the plug and a second explosive extends within a bore defined within the plug. The sensitivity of the second explosive is greater than that of the first explosive so that, upon detonation by an externally actuated elongated detonation member, sequential detonation of the second explosive and the first explosive occurs.
