Abstract

The invention provides a pulse current auxiliary self-resistance heating device and a method for partial quick brazing by utilizing the same, relates to a heating device and a method for quick brazing by utilizing the heating device, and aims to solve the problems that during existing welding, a base material and brazing filler metal need to be heated integrally, the energy consumption is high, the heating range is large when partial heating is performed, and a temperature field is uneven. The device comprises a press machine upper plate, a press machine main cylinder, two press machine guide rails, a press machine sliding block, a first ceramic insulating plate, a second ceramic insulating plate, a first electrode, a second electrode, a pulsed power supply, a press machine platform, a first wire and a second wire. The method comprises the steps of adjusting the press machine sliding block to press a first welding base body, the welding brazing filler metal and a second welding base body; causing the pulsed power supply to supply power to the first electrode and the second electrode, heating an area between the first electrode and the second electrode, applying pressure, maintaining the pressure, and performing welding. The device is suitable for partial quick brazing.

Description

technical field [0001] The invention relates to a heating device and a rapid brazing method using the same. Background technique [0002] The main principle of brazing is to use the characteristics that the melting point of the solder is lower than the melting point of the base material, and to realize the welding of the base material by controlling the temperature field to melt the solder. The area where the brazing of most parts actually needs to be heated is usually local, and how to meet the precise control of the local temperature field is the key to controlling the brazing quality. At present, the traditional brazing method mainly realizes heating by heating furnace, induction heating or flame heating. For the heating furnace, its temperature is uniform, but the unnecessary heating area is too large, and usually small-scale local welding also requires overall heating, and the energy utilization rate is not high. Although induction heating and flame heating can roughl...
