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.
