30pcs(pcs Welding Rod Welding Wire, Powder-free Welding Rod Universal Soldering Tin Welding Accessories, Low Temperature Aluminum Welding Wire (Color : 50PCS-1.6MM*50CM)

Product Name Aluminum Aluminum Welding WireUnit weight 0.5kg/1.0kgFlux content 15-20%Type of coreMelting point: 577℃-582Wire diameter 1.6mm/2.0mmScope of application: aluminum and aluminum brazingApplicable process It can be used for automatic flame brazing, manual brazing, brazing in an atmosphere protection furnace, high-frequency brazing, etc.Instructions for use of low-temperature aluminum and aluminum welding wireThe first step: through physical cleaning, polishing the surface, cleaning the surface of the welded material, and using a steel brush or copper brush to remove the electroplating layer, corrosion, paint, oil, oxide, etc.Step 2: Heat the surface of the base material at the welding place (do not directly burn the welding rod) until the temperature reaches the working temperature of the welding wire 550 degrees, the welding rod can be heated close together, so that the welding rod can be melted by the heat conduction of the base material to form a weld. , And only when the surface temperature of the base metal is sufficient, the welding wire can flow and penetrate to the Jinzhan capillary well.The third step: when repairing thin aluminum parts, just heat the aluminum base material to a suitable working temperature, and then use the welding wire to friction and melt back and forth to form a weld. .
