    摘要: The process is characterized in that hot gas are blown at right angle with the front face of the parts to be brazed into the contiguous areas of an enclosure. The speed of the hot gas in a first area is regulated in order to ensure pre-heating, the speed in a second area is regulated in order to increase the temperature to the brazing temperature and the speed in a third area is regulated in order to ensure at least a partial cooling of the parts before they are withdrawn from the enclosure.

    摘要: Tube passages slightly bigger than the tubes are formed in a plate. A soft resilient sheet is placed on one side of the plate. The tube is forcibly inserted in the tube passages and draws a portion of the sheet which is then cut. In the assembly the sheet, which has a bigger thickness than the interval between the tube and the tube passage, forms a flange beyond the tube plate.
