20pcs pcs(pcs Aluminum Welding Rod, Universal Low-temperature Welding Core Wire Multi-purpose Aluminum Repair Rod, Used for Welding Alloy, Stainless Steel, Galvanized Steel, (Color : 30PCS-1.6MM*

Low-temperature aluminum flux-cored welding wire can weld almost all white metals, including aluminum, aluminum alloy, aluminum-magnesium alloy and dissimilar welding between the above metals, even for white metals that have been severely corroded or contaminated by oil, and even aluminum that is considered irreparable. All alloys can be repaired. Suitable for all-round welding by primary welding operators, only a small heating device is needed. The strength of the weld after welding is generally higher than the strength of the base metal itself. It is enough to know the gas welding operation.Instructions for use of low temperature aluminum welding wireOne step: through physical cleaning, polishing the surface.Step 2: Heat the surface of the base metal at the welding place 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 metal to form a weld. When the surface temperature of the material is sufficient, the welding wire can flow and penetrate into the metal capillary well.Three steps:When repairing thinner aluminum, just heat the aluminum base material to a suitable working temperature, and then use the welding wire to friction and fuse to form a weld. Only use a metal brush to melt the welding wire to fill the weld to form a weld.Four steps:Small parts are welded with propane gas, and large parts are heated and welded with industrial gas or induction heating device. Naturally slow cooling after weldingPrecautions:The thicker the piece, the more troublesome it will be to heat up, so it is very important to use a reasonable heat source, as long as the surface temperature of the base material reaches the level of the welding wire.Working temperature, welding can be carried out. When using oxyacetylene welding, use neutral flame welding, but do not use fire welding wire directlyApplicable heat source: It can
