Abstract
A method of manufacturing a vehicle radiator including joining the liquid conducting tubes to the tank headers by punching holes with upstanding collars in the headers and inserting a tube end in each collar, each collar to tubing joint being formed by welding an intermediate portion of the joint and filling the rest with solder thereby forming a composite joint of weld and solder with additional solder forming a fillet behind the weld.
Claims2
The method of joining a plurality of liquid conducting tubes to a header in a storage tank of a vehicle radiator, said method comprising the steps of forming a plurality of openings in said header plate, each opening being formed with an upstanding collar facing the tank side of the header, placing a tube in each of the header openings so that an end portion of each tube defines a peripheral gap with an associated collar, placing the tubes and header in a welding fixture with the tube and collars facing upwardly beneath linearly movable welder, moving the welder in a linear path to form focused welds at medial portions of each peripheral gap, and filling the remaining portions of the peripheral gap with solder.
