JJHXSM Copper Aluminum Welding Rod 20PCS General Low-temperature Welding Core Wire Multi-purpose Repair Rods for Welding Alloys, Stainless Steel, Galvanized Steel, Copper 0.06x13Inch/1.6x330mm

Instructions for use of aluminum welding wire Step 1: Physically clean the polished surface. Step 2: Heat the surface of the base material to the temperature of 380-400degree centigrade on the welding line at the welding place, so as to form the welding with the thermally conductive welding line of the base material. Do not burn the wires with flames. Only when the surface temperature of the substrate is sufficient, the wires can flow into the metal capillary well. Step 3: When repairing relatively thin aluminum materials, heat the aluminum-based material to a suitable working temperature, and then friction and melt back and forth to form a welded joint. Only metal brushes are used for filler welding to form a weld. Step 4: Use propane gas to weld shopping mall objects, use industrial gas or induction heating device to heat and weld large objects, and cool down naturally and slowly after welding.
