Soldering of aluminum tube for mobile communication antenna_Kehua
Soldering of aluminum tube for mobile communication antenna Soldering of aluminum tube for mobile communication antenna adopts the following welding methods: 1. Argon arc welding is commonly used, and the welding wire is 4 series, 5 series, and 6 series. Hardware stores sell them, but this type of welding does not meet the performance requirements of communication signals and is not recommended. 2. The low-temperature M51 and M51-F welding wire are operated in an environment with a working temperature of 179 degrees. They have good affinity for welding materials of series 1, 2, 3, 4, and 6, and are mostly used for particularly strict deformation control requirements. , or the welding in the case of special thinness, it is recommended to use tin brazing of the aluminum tube of the mobile communication antenna. 3. WE53 low temperature aluminum electrode For welding 7 series of aluminum alloys, the welding working temperature is 380-400 degrees. The advantage is that it does not need to assist any flux welding during welding, so as to prevent some flux during the welding process. Residues, and the welding strength is very high, which can solve the welding of 3 series aluminum alloys and castings, or die castings. If the temperature is too high, it is not recommended. 4. Q303 low-temperature aluminum welding wire also has some special advantages for the weldability of 1, 2, 3, 4, and 6 series of aluminum alloys. It is not recommended for narrow gap welding with poor angles, insufficient precision and performance.
