Welding requirements for aluminum tubes

The inner and outer layers of the large diameter aluminum tube are made of special polyethylene material, which is clean and non-toxic. The most important thing is that the middle layer of the large-diameter aluminum tube is aluminum, which not only can block light, but also block oxygen. Large-diameter aluminum tubes add a large amount of antioxidants to prevent material degradation. Antioxidants are extracted into the water retained in the pipeline, which is easy to cause water pollution. Moreover, because there is no light-blocking oxygen-blocking material in large-diameter aluminum tubes, it is easy to breed. Microorganisms cause secondary pollution of water quality.
The welded pipe cannot be heated by the welding torch and then the welding powder is taken because the melting point of the electrode is too low. The successful one-time welding effect is better, because the large-diameter aluminum tube melting cutting tool point is too low, and the aluminum tube is easily deformed when the second time is reheated. The inner liner must be placed with a wet towel to protect it in place, because the welding space is very small, so be sure to pay attention to the protection of the refrigerator.
The welding time should not be too long. Because the melting point is too low, the aluminum tube wall will melt or become thin, and the pressure will be easily leaked. What are the welding requirements for large-diameter aluminum tubes? Aluminum tubes are an auxiliary type of pipe that is used in industry and are mainly used for welding of large pipes.
