What does brazing mean? What are the characteristics of copper brazing furnaces? Kehua
Welding technology is used in various projects. However, the current welding technology has made great progress compared with the past, and brazing has gradually replaced electric welding. Next, Kehua will introduce to you what brazing means, and what are the characteristics of copper brazing furnaces? After the melting temperature, the liquid solder is used to fill the gap of the solid workpiece to connect the metals. When brazing, the oxide film and oil stains on the contact surface of the base metal should be removed first, so that the capillary can play a role after the solder is melted and increase the wettability and capillary fluidity of the solder. According to Kehua's understanding, brazing is divided into brazing and soft brazing according to the melting point of the brazing filler metal. The brazing deformation is small, the joints are smooth and beautiful, and it is suitable for welding precision, complex and components composed of different materials, such as honeycomb structure plates, turbine blades, carbide cutting tools and printed circuit boards. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and excessively thick oxide film to ensure the interface assembly gap. The gap is generally required to be between 0.01 and 0.1 mm. Copper brazing furnace What are the characteristics of copper brazing furnace? (1) The brazing heating temperature is low, the joint is smooth and flat, the change of structure and mechanical properties is small, the deformation is small, and the size of the workpiece is accurate. (2) It can weld the same metal or dissimilar materials, and there is no strict limit on the thickness difference of the workpiece. ⑶ Some brazing methods can weld multiple weldments and joints at the same time, and the productivity is very high. ⑷The brazing equipment is simple and the production investment cost is low. ⑸The strength of the joint is low, the heat resistance is poor, and the cleaning requirements before welding are strict, and the price of the solder is relatively expensive. Now the copper brazing furnace has been accepted by many enterprises. It has the advantages of low heating temperature and smooth joints, and the copper brazing furnace can also weld dissimilar materials.
