高压开关合金触头是油断器、空气断路器及其它类型断路器在分断时耐电弧的重要部件。其材料种类很多,如钨铜合金、钨银合金、银—碳化钨等。目前,国内高压开关合金触头的焊接大都处于手工氧—乙炔气焊的落后水平。为适应祖国社会主义建设事业的发展,在史无前例的无产阶级文化大革命中,我厂焊接工人和技术人员,高举“鞍钢宪法”伟大红旗,对多种焊接新工艺(真空钎焊、氢气炉钎焊、爆炸焊、摩擦焊及电阻钎焊等)进行了试验,认为电阻钎焊技术是比较适合于高压开关合金触头大量生产和高效率的一种好方
High-voltage switch alloy contacts are breakers, air circuit breakers and other types of circuit breakers in arc resistance when an important component. Many kinds of materials, such as tungsten copper alloy, tungsten silver alloy, silver - tungsten carbide. At present, the welding of the domestic high-voltage switch alloy contacts mostly lies behind the manual oxygen-acetylene gas welding. In order to meet the development of the cause of socialist construction in the motherland, in the unprecedented proletarian cultural revolution, our factory welding workers and technicians held high the great red banner of the Ansteel Constitution, and applied various new welding techniques (vacuum brazing, hydrogen furnace brazing , Explosion welding, friction welding and resistance brazing, etc.) were tested, that resistance brazing technology is more suitable for high-voltage switch alloy contacts mass production and high efficiency of a good side
