Background
At present, the alloy contact industry gradually moves to the way of saving silver and protecting environment, and electrical appliance manufacturers gradually use copper alloy contacts to replace silver alloy contacts and replace noble metals with cheap metals on the premise of ensuring the product quality. In order to improve the automatic soldering performance and the production efficiency of the alloy contact, a solder is generally coated on the soldering surface. In the traditional process, solder is manually added on the welding surface of a contact material strip, the solder is melted by high-frequency heating, and then a special tool is used for uniformly smearing the solder liquid, so that the compounding speed is low, the labor intensity is high, the uniformity of the solder and the consistency of the material are difficult to ensure after the added solder is melted, the compounding temperature and the compounding speed are inconsistent, and the infirm welding, the uneven solder layer or the missing welding can be caused.
At present, the sandwich type composite multilayer brazing filler metal is obtained by melting and rolling a brazing filler metal layer and a base material layer. When the brazing filler metal layer and the base material layer are compounded, because the melting point of the base material layer is higher and the melting point of the brazing filler metal layer is lower, if the brazing filler metal layer is preheated and rolled by an annealing furnace after being fixed at a position, the brazing filler metal layer is easy to melt in the annealing furnace; if preheat the laminating respectively with brazing filler metal layer and substrate layer and roll, work efficiency is low, and simultaneously, the substrate layer temperature after preheating is higher, and manual operation is more dangerous, and the brazing filler metal layer is met the easy melting of heat, in case the adhesion just stereotypes basically on the substrate layer, need control well relative position between them during consequently the laminating.
