Abstract

A method of affixing a plurality of tubes into a plurality of corresponding openings in the header wall of a heat exchanger in which the wall has an inner, liquid-facing side and an outer, air-facing side. Ends of the tubes are welded to corresponding collar openings in the header wall, such that the tubes extend toward the air-facing side of the wall, to form a plurality of welded tube-to-header joints. Flux is applied by spraying or the like to the air-facing side of the tube-to-header joints. Thereafter, a lead/tin or other molten solder is applied to the liquid-facing side of the tube-to-header joint by dipping or wave solder techniques and flowed into any voids in the welded joints to substantially seal the joints against leakage of liquid.
Only those joints having potential liquid leaking voids receive the solder; sound, liquid-tight welded joints are not solder sealed.
