【Summary Description】 1, first of all, according to the material characteristics of the workpiece processing, dimensions, the actual welding conditions to design the appropriate sensor; 2, select the power of the power supply, for small workpieces, roughly estimate can do equipment selection. For the large volume of the workpiece and the short heating time, detailed power calculation is required to avoid insufficient welding power; 3. Calculate the specifications of the solder according to the external dimensions and welding requirements of the welding workpiece. Note: The melting point of the solder must be lower than the melting point of the base metal; After melting, the solder can wet and flow well on the surface of the base metal; Can be combined with the base metal to form a strong joint; The ingredients are stable, non-toxic and harmless. 4. Remove the oxide film and oil on the surface of the workpiece; 5. When positioning, supporting and fixing the workpiece to ensure mass brazing production, the relative position of the workpiece and the inductor will remain unchanged, and the brazing filler metal will be added in a ring shape to the part to be welded. 6. Setting of heating parameters: control the brazing temperature and heating speed by adjusting the heating current and heating time; When setting the heating parameters, first switch to the manual mode. In the "manual mode", observe the melting of the solder, and manually "click" to heat to achieve a good welding effect. At the same time, record the approximate heating time to make a good basis for the next adjustment of automatic parameters. Switching the "automatic mode" According to the heating current and the required time in the "manual mode", an automatic parameter can be roughly called out, and heating is performed under the parameter, the heating situation is observed, and the parameter is fine-tuned accordingly, and finally A suitable parameter is obtained. 7, brazing post-treatment: directly put the workpiece into the water, or use other chemical cleaning agent.
