2mm 13 inch 20 Pack Universal Low Temperature Aluminum Repair Rods No Welding Fix Cracks Drill Tap Polish or Paint Silver Aluminum Welding Rods

Aluminum Welding Rods, 20 Pack Universal Low Temperature Aluminum Repair Rods No Welding Fix Cracks Drill Tap Polish or Paint, Silver, 2mm 13 inch - -. 【Dimension】- Diameter 2mm / 0.08", Length 330mm / 12.9“ . 【Great Welding Effect】- With full & smooth welding effect because of internal powder. With low melting point(380℃～400℃), great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance. . 【No Need Solder Powder】- You don't have to use other flux powder with aluminum alloy as the welding core and coating as the salt base. Very convenient and easy to weld. . 【Widely Application】- It is mainly used for argon arc welding and filling material for pure aluminum, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on. . 【Widely Use In Life】- Suitable for welding or surfacing welding alloy with high strength, good forgeability & good corrosion resistance. . Size:13 inch . Instructions for use of aluminum welding wire. Step 1: Polish the surface by physical cleaning.. Step 2: Heating the surface of the base material at the welding place until the temperature reaches the working temperature of the welding wire of 380 ° C - 400 ° C, so that the weld can be formed by the heat conduction welding wire of the base material. Do not use a flame to burn the wire, and only when the surface temperature of the base material is sufficient, the wire can flow well and penetrate into the metal capillary.. Step 3: When repairing the relatively thin aluminum, the aluminum base material is heated to a suitable working temperature, and then the wire is frictionally melted back and forth to form a weld seam. Only the metal brush is used to fill the weld to form a weld.. Step 4: Use propane gas to weld s mall object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding.. Operation attention detail. 1. The surface of the base metal must be cleaned. Clean immediately, weld immediately.. 2. The temperature of the base metal should reach 400 °C, including the temperature of the base metal during the welding process should also be maintained at 400 ° C, and the temperature can be high or low.. 3. Avoid using flame to deliberately burn the welding wire. After the temperature of the base material reaches 400 °C, the welding wire will naturally rely on the thermal conductivity of the base metal.. . . .
