Easy to use: Welding electrodes suitable for complete welding by young welding operators. It only requires a small heating device. The weld strength after welding is usually higher than the strength of the base metal itself. No solder powder required: you don't need to use other solder powders. fluxes with aluminum alloys because the solder core and coating are the base. Very convenient and easy to solder. High Performance: Using the internal powder, the solder wire has sufficient and smooth soldering effect. It also has a low melting point, high weldability and corrosion resistance, high thermal conductivity, high electrical conductivity and excellent processing properties. Welding effect: it can repair aluminum alloy that some people think cannot be repaired, even heavily corroded or oil contaminated white metal can be repaired. Applications: This low temperature aluminum welding wire can weld almost all white metals, including aluminum, aluminum alloy, cast aluminum, aluminum magnesium alloy, etc. High strength, good forgeability and good corrosion resistance. Material: aluminum. Color: silver. Melting point: 647 / 658.< /p> Diameter: 2 mm. Instructions: Step 1: Polish the surface by physical cleaning. Step 2: Heat the surface of the base metal until the temperature reaches the welding wire working temperature of 450C or above, so that the weld can be formed by the base metal thermal conduction welding wire , and the flame welding wire should not be used, and when the surface temperature is sufficient, the wire can flow well and penetrate. Step 3: When repairing the relatively thin aluminum, simply heat the aluminum to a suitable working temperature, then use a wire and wire brush to rub back and forth to form a weld. Caution: 1. The surface must be cleaned. 2. The base metal temperature should be maintained at 450C during the welding process, and the temperature cannot be lower. 3. Avoid using flames to deliberately burn the wire, after the temperature reaches 450, the wire will naturally depend on the thermal conductivity of the base material.
