[NEVER USED] Welding Rods, 20 pieces of 2.0 mm low-temperature aluminum welding electrodes - Easy-to-melt welding rods - Corrosion resistant (33 cm)

Product never used, packaging damaged during transport. Unopened product, repackaged in our warehouses, in perfect working condition, warranty available.

Easy to use: These welding electrodes are suitable for complete welding by novice welders. They only require a small heating device. The weld strength after welding is generally higher than the strength of the base metal itself.

No welding powder required: You don't need to use additional flux powders with aluminum alloys because the weld core and coating are self-contained. 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, high electrical conductivity, and excellent processing properties. Welding effect: It can repair aluminum alloys that some people think cannot be repaired; even heavily corroded or oil-contaminated white metals 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.

Diameter: 2 mm.

Instructions:

Step 1: Polish the surface by physical cleaning.

Step 2: Heat the base metal surface until the temperature reaches the welding wire working temperature of 450°C or above. This allows the weld to be formed by the thermally conducted welding wire to the base metal. Do not use flame welding wire. When the surface temperature is sufficient, the wire can flow and penetrate well.

Step 3: When repairing relatively thin aluminum, simply heat the aluminum to a suitable working temperature, then use A wire and a wire brush for back-and-forth rubbing to form a weld.

Caution:

1. The surface must be clean.

2. The base metal temperature must be maintained at 450°C during the welding process, and the temperature cannot be lowered.

3. Avoid using flames to deliberately burn the wire. After the temperature reaches 450°C, the wire's thermal conductivity will naturally depend on the base material.
