How to weld automobile aluminum water tank with gas welding 4047 welding wire?

The methods and skills of gas welding 4047 welding wire welding aluminum water tank generally focus on mastering the temperature control and the cooperation of aluminum welding powder.

Key points: the temperature of 4047 is close to 600 degrees, which is very close to the melting point of the base material, especially the riser of the thin water tank. When the temperature is a little higher, the riser will break, so it is very important to adjust the fire when heating, and then reduce the heating mode to match the process of lifting the flame up when heating, because this short cooling is to heat the base metal more safely.

Details: Small-angle heating and dipping welding powder with welding wire are also small-angle applications of weldments. At the same time, the welding wire dipped in welding powder is heated by flame. If the temperature is enough, the welding powder will change from powder to water, and then when the substrate turns white, the temperature is enough, and the welding wire will flow like water.

Suggestion: 4047 is generally suitable for experienced gas welders. If you are a novice, you can also use low-temperature welding wires with M5 1-F flux, such as 179 degrees, with Viodin 303 at 430 degrees and WEWELDING 53 at 385 degrees. These operations are relatively simple, because there is no need to worry about burning the base material at low temperature.
