Low-temperature aluminum wire can weld almost all white metals, including aluminum, aluminum alloy, cast aluminum, aluminum magnesium alloy and dissimilar welding between the above metals, even for the white metal that has been seriously corroded or polluted by oil, and even the aluminum alloy that is considered to be irreparable can be repaired. It is suitable for the primary welding operator to weld in all direction, only need a small heating device, the strength of the weld after welding is generally higher than the strength of the base metal itself, know the gas welding operation.
Instructions for use of low temperature aluminum wire
Step 1: Sand the surface through physical cleaning.
Two steps: heat the surface of the base metal at the welding place, until the temperature reaches the working temperature of the welding wire of 380ºC-400ºC, so that you can rely on the heat conduction of the base metal to melt the welding wire to form a weld. Do not use the flame to burn the welding wire, and only when the surface temperature of the base metal is enough, the welding wire can flow well and penetrate into the metal capillary.
Three steps: when repairing the thin aluminum, as long as the aluminum base metal is heated to the appropriate working temperature, and then the welding wire is rubbed back and forth to form a weld, only the metal brush is used to fill the molten welding wire in the welding place to form a weld.
Operation attention to detail
1. The surface of the base metal must be cleaned. Is the qing is welding
2. The temperature of the base metal must reach 400ºC, including the temperature of the base metal in the process of welding to maintain 400ºC, and the temperature can be high or low.
3, taboo flame deliberately to burn welding wire, base metal temperature reaches 400ºC, welding wire will naturally rely on the base metal heat conduction melting.
