A wished that the Shenzhou No. 9 manned spacecraft was successfully docked. As everyone knows, the aerospace project is an extremely complicated and huge project. The selection of spare parts is extremely demanding, even if it is as small as a screw, in fact, as early as the last century 70 In the 1980s, nylon fastener products manufactured by Wulian Plastics Nets were used in the NASA (NASA) aerospace project, as well as in the satellite and Hubble Space Telescope projects.
When welding the bent pipe, if there is an inadvertent phenomenon, it will definitely cause damage to the components, or it may cause poor welding. If the pipe is welded, it is lead alloy or welded. When the surface belongs to copper, the solder should first be wetted, and the solder will gradually diffuse into the metal copper, and the solder and the metal copper can be effectively adhered to ensure a firm and reliable combination. Before welding, the elbow is usually processed. When the elbow is processed, the roughness of the outer wall surface of the workpiece is related to the surface roughness of the ring groove on the bender wheel, and also related to the nature and quality of the pipe. In order to make the workpiece look smoother after processing, as long as the surface of the ring groove of the wheel is coated with a suitable lubricating oil to reduce the friction between the surfaces in contact with each other during operation, the curved metal can be ensured.
The roughness of the outer wall surface of the pipe meets the requirements of the index. After that, Tianjin CNC bending process is used to wet the elbow. The wetting mainly refers to the molten solder, the capillary and the surrounding flow along the base material, and can form a surface on the base material to be welded. The layer adhesion layer ensures that the atoms between the solder and the base material can be close to each other. When we start to wet the elbow, the interdiffusion between the solder and the base metal has actually begun. An intermediate layer is formed between the two metals. In fact, it is often called a metal compound, if you want to get better welding. At the point, a good metal compound must be formed between the base metal and the solder to ensure the firmness of the base material.
