Low Temperature Aluminum Welding Wire, 50pcs 2mm Aluminum Repair Rods No Need Solder Powder Convenient Welding Wire (33CM)

• Low Temperature Welding Wire: Low temperature aluminum welding wire is an aluminum-silicon eutectic welding wire with 12% silicone. It has a lower melting point and finer solidification range than 4043 solder wire. It has a high silicone content, good fluidity and minimizes the tendency to thermal cracking. Increases the shear strength of the weld.
• No Solder Powder Needed: You don't need to use other core powders with aluminum alloys because the solder core and coating are the base. Very practical and easy to solder
• Welding Effect: It can repair aluminum alloy that some people think cannot be repaired, even white metal which is seriously corroded or contaminated by oil can be repaired.Melting Temperature: 380℃-400℃
• Wide Use: Low temperature aluminum welding wire is suitable for welding or welding alloy surface with high strength, good formability and good corrosion resistance
• Easy to Operate: Suitable for all-round welding by junior welding operators. It only needs a small heating device. The welding strength after welding is usually higher than the strength of the base metal itself.

Low Temperature Welding Wire: Low temperature aluminum welding wire is an aluminum-silicon eutectic welding wire with 12% silicone. It has a lower melting point and finer solidification range than 4043 solder wire. It has a high silicone content, good fluidity and minimizes the tendency to thermal cracking. Increases the shear strength of the weld. Instructions for use of low-temperature aluminum welding wire Step 1: Physically clean and polish the surface. Step 2: Heat the surface of the base material at the welding point until the temperature reaches the working temperature of the welding wire 380℃-400℃, so that the welding wire can be melted by the heat conduction of the base material to form a weld. Do not burn the welding wire with a flame. Only when the surface temperature of the base material is sufficient can the welding wire flow and penetrate into the metal capillary well. Step 3: When the aluminum is relatively thin, just heat the aluminum base material to a suitable working temperature, and then use the welding wire to rub back and forth to melt and form a weld. Only by brushing the molten welding wire with a metal brush can the weld be formed. Four steps: Small pieces are welded with propane gas, large pieces are welded with industrial gas or induction heating device, and naturally cooled after welding Precautions: The thicker the piece, the more troublesome it is to heat, so it is critical to use a reasonable heat source. As long as the surface temperature of the base material reaches the working temperature of the welding wire, welding can be carried out. When using oxyacetylene welding, use neutral flame welding, but do not burn the welding wire directly with fire Applicable heat source: It can be used for many kinds of heat sources, such as propane, oxyacetylene, etc. Storage: Place in a ventilated and dry place for long-term storage Operation attention to details 1. Clean the surface of the base material. Clean and weld 2. The temperature of the base material must be 400℃, including the temperature of the base material during welding. It must be maintained at 400℃, and the temperature can be high but not low. 3. It is taboo to deliberately burn the welding wire with a flame. After the base material temperature reaches 400℃, the welding wire will naturally melt by heat conduction from the base material.
