Description

Technical Field

[0001] The utility model belongs to the field of bellows welding, in particular to a bellows rotary brazing welding device. Background Art

[0002] Brazing is a metal-to-metal welding method in which a filler metal (a material with a melting point lower than the melting point of the workpiece) and the workpiece are heated simultaneously to the melting point of the filler metal. Liquid filler metal then fills the gap between the solid workpieces, creating a joint. During brazing, the oxide film and oil stains on the contact surface of the parent metal must be removed to facilitate capillary action after the filler metal melts, thereby increasing the filler metal's wettability and capillary flow. Brazing is categorized into hard soldering and soft soldering, depending on the filler metal's melting point.

[0003] In the prior art, when brazing bellows parts, workers need to place and position the parts one by one, and heat and weld them one by one. This has poor work efficiency, and the heating coils heat the parts for a short time, resulting in different temperatures at different circumferential positions of the parts' welds, making the welding quality uncontrollable.
