Abstract
The method of joining the contiguous surfaces of telescoped end portions of tube members wherein at least one of the surfaces to be joined is coated with a layer of solder. A heated forming means is applied to the telescoped end portion to reflow the solder while simultaneously applying sufficient pressure in a radial direction to progressively reduce the radial clearance between the end portions in an axial direction toward the open end of the female member. The temperature and pressure applied is sufficient to provide melted solder between the surfaces to be joined as the crimping action proceeds axially so that excess solder is forced hydraulically out of the open end of the female member as the radial clearance is progressively reduced to a minimum. The scrubbing action of the molten solder as it is forced progressively from the radial clearance is effective in removing the oxide from the surfaces to be joined thereby completing a joint between the members.
