Temperature definition The melting point of pure aluminum: 660.37 degrees Celsius, while the aluminum alloy with its different alloying elements, the melting point of 482-660 degrees Celsius. When aluminum and aluminum alloy are heated from normal temperature to melted state, there is no color change. It is very difficult to judge the temperature of the base metal during welding, which makes it easy to overheat or melt the base metal. Low temperature aluminum wire temperature is currently defined in three temperature intervals. Low temperature aluminum wire temperature is currently defined in three temperature intervals 1,580-620 degrees Celsius low temperature aluminum wire. Representative wire ER4047, ER4043 2,380-450 degrees Celsius low temperature aluminum wire. Representative wire Q303, WE-Q303B, WE53 and so on 3,179 degrees Celsius low temperature aluminum wire. Representative wire M51, M51-F 2 welding principle By the base material of the heat conduction, and slightly to assist the flame melting wire molding. 3 welding method 1, clean up: cleaning is to be welded parts to mechanical cleaning as the best, the purpose is to remove the surface oxide film. 2, heating: focus on thick parts heating, heating can be a little farther away from the welding distance, without having to go directly to the welding mouth. 3, cutting: to reach 400 degrees temperature, under the wire. Point of view as far as possible perpendicular to the welding point, point the moment with a little flame on the end of the tip of the wire melting melt shape, the tip of the wire, instead of deliberately burning wire. 4 industry range 1, the cooling industry, the socket of aluminum tubes, central air-conditioning copper and galvanized pipe, stainless steel pipe, aluminum pipe of dissimilar welding. 2, the substation industry aluminum terminals, aluminum leads, aluminum conductive row of welding. 3, electronic industry, radiator pipe, motor, bus welding. 4, the other for the production of life faucet, coupling connector, supporting the nut and so on.
