The u-shaped copper tube is one of the more materials used in industrial equipment. The u-shaped copper tube is not only hard in texture, is not easily deformed, and has a long service life and does not need to be replaced. But many times, the use of u-shaped copper tubes requires some processing, and welding is one of the most important steps.
Brazing principle of U-shaped Copper Tube welding: Brazing is to use a solder having a lower melting point than the base material to be heated together with the base material. In the case where the base material is not melted, the solder is melted, wetted and filled into the two parent materials. The gap at the place forms a brazed joint in which the solder and the base material dissolve and diffuse each other, thereby obtaining a firm bond. Brazing of copper tubes is to heat copper tubes and copper tubes together with copper-phosphorus solder or tin solder having a lower melting point than copper.
When the copper tubes and copper tubes are not melted, they are heated until the solder melts, and then The molten solder is filled into the gap of the socket, and the crystal is cooled to form a brazed joint, which becomes a firm joint. When the copper tube is brazed, the gap of the socket is small, the solder needs to pass through the capillary to enter the gap of the joint, and the capillary action can only be formed when the liquid solder can wet the copper surface, otherwise the liquid solder Under the action of surface tension, it will agglomerate into a spherical shape, which will form a non-wetting phenomenon. Therefore, the wetting of the copper surface by the liquid solder is the key to whether the solder can flow into the brazing seam and fill the brazing seam.
