Abstract: This is a process relating to improvements in the soldering of headers to conventional radiators. Tubular members of the radiator extend through holes in the header. The tubes are initially sealed to the header with a solder having a high temperature melting point T.sub.1. Infrared heat heats the header to a temperature T.sub.2 which is less than T.sub.1 but above a lower temperature T.sub.3 which is the melting temperature of a second solder. Upon the header reaching a selected temperature T.sub.2, a selected amount of the second solder in a molten state is poured in the header to puddle the entire pan area of the header, and allowed to cool to form a very strong soldered connection.

Abstract: A method of arc welding is disclosed. Specifically, a method of pulsed direct current (DC) arc welding is disclosed wherein special pulses of positive direct current are used to weld together work pieces. The special DC pulses are capable of dissipating difficult to reduce oxides which may be present on the surfaces of the work pieces without using a flux. The method is especially useful for fluxless arc welding of aluminum, particularly thin wall aluminum tubing used in making heat exchangers for air conditioning systems.

Abstract: The ultrasonic soldering of continuously drawn coilable aluminum tube to provide soldered socket joints is improved where the tube, after continuous and sequential drawing to produce a work hardened tube, is subjected to a burnishing operation by being drawn through a burnishing die. The burnishing operation differs from the drawing operation used to produce the continuously drawn tube in that the burnishing does not substantially alter the wall thickness of the tube. The burnishing dies condition the outer tube surface to be more wettable by molten solder metal in fluxless ultrasonic soldering processes.

Abstract: A method and apparatus for soldering tubular, metal return bends to the ends of tubes in which the article carrying the tubes with the bends secured thereto is first pivoted around a horizontal axis from a horizontal loading and unloading first position to a second position in which the bends and tube ends are immersed in molten solder in a pot and is then pivoted around such axis into a third position in which the bends are above the ends of the tubes, the solder between the ends of the tubes and the bends being permitted to cool and solidify in the third position. Intermediate the first and second positions and intermediate the second and third positions, pivotally mounted burners heat at least the bends to a temperature at least as high as the melting temperature of the solder, the heating between the second and third positions being for the purposes of causing any solder in the bends to flow out of the bends and of minimizing or eliminating icicles of solder on the bends. The apparatus includes a pivotable support for the article, skimming apparatus for stirring, and displacing dross on, the solder in the pot, ultrasonic solder agitating apparatus, burner oscillating apparatus and controls for automatically operating the parts in the desired sequence.

Abstract: This invention relates to apparatus for facilitating the construction of a heat exchanger, such as a condenser or evaporator employed in an air conditioning system, wherein exchanger tubes extending through a plate fin assembly are joined together by means of return bend connections or the like. The ends of the tube are provided with an oval shaped bell in which are telescoped the return bends. Diametrically opposed nibs are formed on the outer surface of the return bend connectors near the distal end thereof. The outside diameter over the nibs is slightly larger than the minor inside diameter of the oval bell. The nibs are inserted into the bell aligned along the minor diameter of the opening. The nibs are thus caused to ride in engagement against the wall of the bell to frictionally support the connector in assembly. The joint is then immersed in a molten solder bath whereby solder flows freely into the joint region along the major axis to create a highly reliable joint.
