Welding Rod, 20 pieces 2.0 mm low temperature aluminum welding electrodes - Easy to melt welding rods - Corrosion resistance (33 cm)

Easy to use: welding electrodes suitable for complete welding by young welding operators. It only requires a small heating device. The welding strength after welding is generally higher than the strength of the base metal itself. No welding powder required: you do not need to use other flux powders with aluminum alloys because the welding core and coating are the base. Very convenient and easy to weld. High performance: By using the internal powder, the welding wire has a sufficient and smooth welding effect. It also has a low melting point, high weldability and corrosion resistance, high thermal conductivity, a conductivity high electrical 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 and magnesium alloy, etc. High strength, good forgeability and good corrosion resistance. Material: aluminum. Color: silver. Melting point: 647 / 658. 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 working temperature of the welding wire of 450 °C or above, so that the welding can be formed by the welding wire to heat conduction of the metal of base, and the welding wire to the flame should not be used, and when the surface temperature is sufficient, the wire can circulate and penetrate well. Step 3: When repairing relatively thin aluminum, it is sufficient to heat the aluminum to a suitable working temperature, then use a wire and wire brush to rub back and forth to form a weld. Attention: 1. The surface must be cleaned. 2. The temperature of the base metal must be maintained at 450 °C during the welding process, and the temperature cannot be lower. 3. Avoid using flames to deliberately burn the wire, after the temperature reaches 450 °C, the wire will naturally depend on the thermal conductivity of the base material. Contents: 20 aluminum welding wires (33 cm/50 cm). Note: All data are manual measurements, please allow an error of 1 - 3cm. Due to differences in light and display, there will be some color difference, subject to the physical object received. Delivery quantity: (according to the main picture)
