Abstract

The invention discloses a precision resistance brazing method for stranded conductors and fine wires. The method comprises the steps of filling brazing filler metals and brazing flux into a groove ofa grooved graphite block; matching the size of the brazing filler metal with the size of the groove of the grooved graphite block; flat placing the part, to be welded, of the stranded conductors ontothe brazing filler metals; energizing and heating the grooved graphite block with a welding power supply, and obtaining the stranded conductors infiltrated with the brazing filler metals; moving awaythe stranded conductors infiltrated with the brazing filler metals from the groove of the grooved graphite block; filling the brazing filler metals and the brazing flux into the groove of the groovedgraphite block; putting the fine wires on the center part of the brazing filler metals; putting the stranded conductors infiltrated with the brazing filler metals on the fine wires; and energizing andheating the grooved graphite block with the welding power supply so that the stranded conductors are connected to the fine wires by brazing. The brazing method disclosed by the invention is easy to operate, and a joint obtained is filled with the brazing filler metals; and the joint performance is superior to the performance of a conventional resistance brazed joint.

Description

technical field [0001] The invention relates to the field of welding of small-sized joints, in particular to a precision resistance brazing method for multi-strand wires and fine wires. Background technique [0002] Sensing components in avionics systems are important parts, and their manufacture often requires welding multi-strand wires and micro-wires together. The welding quality of the joints is very high, but the diameters of multi-strand wires and micro-wires vary greatly, and the materials used Generally, they are dissimilar materials, and the fine wires are easily softened by heat. These problems make the multi-strand wires and the fine wires unsuitable for connection by fusion welding. At present, the connection of such parts is mainly by brazing, mainly including flame brazing and resistance brazing. Flame brazing is mainly manual operation, which requires high level and experience of welders, and manual operation cannot Strictly control the heat input of the join...
