20-100X Aluminium Low Temp Welding Rods Durable Flux Cored Brazing Repair Sticks

Feature:

1. Made of high-quality aluminum, high hardness and high strength, strong and durable.
2. The welding rod is smooth and shiny, and the welding effect is full and smooth. With low melting point (about 480℃), great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance.
3. No other flux is required. Easy to use and easy to weld.
4. Four different product specifications are available for you to choose to meet your different needs.
5.Suitable for aluminum alloy welding, such as aluminum, aluminum alloy, aluminium-magnesium alloy and so on. (Cannot be used for welding copper or stainless steel.)

How to Use:
1. Clean and polishe the physical surface.
2. Heat the surface of the base material, until the temperature of the wire up to the operating temperature of 380℃～400℃, so you can rely on the parent metal heat transfer welding wire to form welds. Do not use the flame to burn wire. When the surface temperature of the base metal is sufficient, the wire can flow well and penetrate the metal capillary.
3. When repairing thin aluminium, as long as the aluminium base metal is heated to the appropriate working temperature, use the wire back and forth friction melting to form a weld, only with a metal brush melt welding wire to weld at the weld.

4. Use propane gas to weld small object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding.

Note:

 1. Scrub the base with a stainless steel brush until it is shiny, thoroughly cleaning the area to be soldered. The area to be soldered is then uniformly heated. When heating, rub the rod vigorously over the heating area until the rod begins to flow.
 2. Don't use the fire to burn welding rod directly as it may break. ( If you try to melt the welding rod directly, the weld will easily break. )
 3. Keep in mind that directly melting the welding rod is the wrong method and will create welds.
 4. The base metal temperature should reach 400℃, including the process of welding the base metal, the temperature should be maintained at 400℃ or above.
