Abstract
PURPOSE: Small and large diameter pipes are overlapped and ultrasonically soldered in a soldering bath. While the pipes are moving up from the bath, one or more of ultrasonic vibrations are applied to them to remove imperfect solder portions and to provide a good joint with high reliability.
CONSTITUTION: A copper or other inside pipe 12 is soldered at its tip end and inserted into an aluminum or other outside pipe 11 to a predetermined depth. Both pipes are soldered together in a soldering bath using ultrasonic vibration. When pipes 11 and 12 are lifted from the bath, ultrasonic vibration is again applied. This causes to lower the molten solder between pipes, to remove unalloyed portion 13a produced on joint surface, and maintain wettability between solder and pipes. The pipes are then cooled. To be more effective, ultrasonic may be applied more than one times before the end of outside pipe 11 leaves the surface of soedering bath.
