Welding bent pipes is a technical activity. The principle of bent pipe welding is to use a heated soldering iron to directly heat and melt the solid solder wire, and then use flux to ensure that it can flow smoothly into the metal being welded. After it is completely cooled, a reliable and sturdy welding point can be formed.
If the welding surface of the tin lead alloy is mainly made of copper during bending pipe welding, it is necessary to ensure that the solder is wetted on the surface of the welding. Due to the continuous occurrence of wetting, it is necessary to ensure that the solder is dispersed in the direction of the copper metal and effectively ensure the effect of the adhesion layer, promoting favorable bonding on both sides.
What are the issues to pay attention to when welding bent pipes?
Ensure that the bent pipe is wetted during welding: The wetting process of the bent pipe is actually to spread the melted solder along the metal base material using capillary force, forming small concave convex crystals, and then attaching them to the surface of the welded base material, ensuring sufficient contact between the solder and the metal base material and exerting atomic attraction. And bending pipes also have requirements in humid conditions and environments, among which the cleanliness of the surface of the welded base material is very important. It cannot show pollutants or oxides, which are necessary conditions to ensure the welding of the base material. Therefore, everyone should be careful and not be careless during the welding process.
The phenomenon of dispersion of bent pipes during welding: Due to the continuous wetting of bent pipes, the solder and base metal will be dispersed from each other. Normally, the lattice points at this time are in a state of thermal oscillation. When the temperature continues to rise, the activity of atoms will also increase, ensuring that the melted solder and base metal are closer together.
The metallurgical bonding situation when welding bent pipes: Due to the dispersed state between the solder and the base material of the bent pipe, and the fact that both metals form an intermediate layer with each other, which is actually what we commonly refer to as a metal compound, the obtained welding points are also quite outstanding. Therefore, it is necessary to present the chemical properties of the metal between the base material and the solder to be welded物。
