ALCU-Q303 low copper aluminum copper and aluminum wire copper and aluminum flux cored welding flux cored aluminum cryogenic WE genuine brand Weiou Ding Wei Ouding from copper and aluminum flux cored wire (Tianjin) Co., copper and aluminum cored wire welding technology technical parameters : Working temperature brazing ℃: 385-400 Tensile strength MPa: 150 ~ 160 color matching aluminum good conductivity Good Good resistance to high temperature corrosion resistance of copper and aluminum flux cored good range of applications: 1) copper and aluminum tube refrigeration industry The socket, central air conditioning copper and galvanized pipe, stainless steel, aluminum welding dissimilar. 2) copper and aluminum terminals, copper and aluminum wire, copper and aluminum conductive row welding transformer industry. 3) electrical and electronic industry, radiator pipes, motors, welding bus. 4) Another life for the production taps, coupling connector, supporting the nut and so on. Copper and aluminum flux cored use of technology: 1) with special stainless steel brush to clean under WE53 is welded metal weld oil, dirt, insulation, exposed metallic luster allowed. 2) tooling up the required welding parts, welding parts generally recommended clearance required for 0.05-0.1mm, with WE53 special porous gun (WE53 that burn liquefied LPG gun, which will emit a wide flame with flame more suitable for regional heating, which can be of a more uniform heating member) uniformly heating the base material to be welded, until the temperature of the base material uniformly increased to about 300 degrees, the main heat source concentrated at the heat welding predesigned while moving the heating base metal to be welded, the heating sequence is thick pieces of thin pieces after the first, after the first copper aluminum. 3) to be welded at the welding temperature reaches about 400 degrees to fill a certain angle welding seam weld at (angle sufficient to melt the wire welded to weld appropriate), the temperature of the base material must reach 400 degrees. When parts to be welded to form a uniform weld filler metal in welding, torch away, natural cooling, the entire welding process is complete, this process does not try not to burn ALCU-Q303 copper and aluminum wire, because it is different from traditional wire This principle is the thermal conductivity of the base material by melting copper and aluminum cored wire forming ALCU-Q303, you can use a little flame burn at the end of the wire flux, but do not directly burn with fire wire. 4) After cooling does not need further treatment, the weld surface visible non-corrosive flux, if the conditions are available a wire brush or a dry cloth to wipe the paint!
