Problems solved by technology
This method only ensures the weld gap in the combined state. During the brazing process, the parts to be welded and the overlapping materials will be thermally deformed at the brazing temperature. At this time, the gap of the weld without support will also change, affecting Solder capillary action and overall component dimensions when filling welds

Abstract
The invention relates to the field of vacuum brazing, in particular to a vacuum brazing method which comprises the steps that the surface of a to-be-welded part is filled with alloy wires; the plane where the alloy wires are located is perpendicular to the welding face of the to-be-welded part. Bending one end of the alloy wire into the welding surface of the to-be-welded part; a plurality of to-be-welded parts are arranged; all the to-be-welded parts are combined, so that the alloy wires are attached between every two welding faces of the to-be-welded parts; and all the to-be-welded parts are fixed pairwise through alloy sheets. By means of the method, the welding seam gap can be accurately controlled, and the welding seam quality and the size of welded parts are prevented from being affected.
Description
technical field [0001] The invention relates to the field of vacuum brazing, in particular to a vacuum brazing method. Background technique [0002] Vacuum brazing is widely used to join high-end manufacturing components. The brazing process mainly relies on the capillary action of the filler metal in the weld to fill the weld, so the control of the weld gap has a great impact on the welding quality. At the same time, due to the high dimensional accuracy requirements of the welded parts, once the weld gap is not strictly controlled, it will affect the overall size of the welded parts. [0003] The existing welding seam gap control method mainly relies on the feeler gauge to measure the welding seam gap during spot welding positioning, and then realizes the welding seam gap during the combination process by overlapping the spot welding alloy wire or alloy sheet on the outside of the welding seam. control. This method only ensures the weld gap in the combined state. During ...
