C12300 brass pipe has the following welding methods:

1. Brass welding wire is used for high temperature welding with flux paste. This welding method is more suitable because the melting point of brass is relatively low, while the temperature of brass welding wire such as HS221 welding material is high, which is closer to the melting point of brass.

2. Silver welding can be divided into low-silver and high-silver welding according to the content, low-silver representative 202A solder, high-silver representative A203, among which the toughness and strength of high-silver solder are significantly better than that of low-silver. The soldering process The melting point temperature of medium and high silver is 600 degrees, and that of low silver is 650-700 degrees.

3. Low-temperature brazing can be welded with low-temperature tin alloy. This is used when there is no special requirement for mechanical strength. Generally, after preheating with a small flame gun or electric soldering iron, the welding wire is then coated with flux to the welding part. The heat conduction of the mother body is used to melt the flux-dipped solder wire forming, which represents, for example, the low temperature 179°C M51 alloy solder combined with the M51-F flux soldering.

4. Argon arc welding. This kind of C12300 brass pipe is relatively thick and thick. Generally, brass with a thickness of 2 mm or more takes into account that the temperature uniformity control is not as good as thin materials. Therefore, argon arc welding is generally used, and the brass contains zinc. The quantity is relatively high. There may be smoke when welding with traditional HS221, and welding cannot be performed normally. Therefore, this kind of Weiolding brass argon arc welding wire, which is generally used for argon arc, has an air pressure of 8L/min and a welding current. Taking the ability to open the molten pool as the standard, the welding method is mainly to add wire.
