welding alloys

Aluminum welding protection measures1, before welding by mechanical or chemical Welding Material means clear the groove and the surrounding part of the workpiece and the wire surface oxides;2, the welding process to be used to protect a qualified protective gas;3, in the welding, the use of flux in the welding process continuously welding wire prick pool surface oxide film. var addthis_config = {"data_track_addressbar":true};

aluminum welding industry range1, the refrigeration industry copper and aluminum tube sockets, central air conditioning copper and galvanized pipe, stainless steel, aluminum welding dissimilar.2, transformer industry, copper and aluminum terminals, copper and aluminum wire, copper and aluminum Welding Rod conductive row welding.3, the electrical and electronic industry, radiator pipes, motors, bus welding.4, and the other for the production of life faucets, coupling connector, supporting nuts, etc. var addthis_config = {"data_track_addressbar":true};

Aluminum welding weld cleanup requirements1, in hot water using a stiff brush scrub carefully welded joints.2, the weldment at a temperature of 60 ~ 80 ℃, mass fraction of 2% to 3% aqueous solution of chromic acid or potassium dichromate solution dipping about 5 ~ 10min, and carefully Welding Electrode Materials scrubbing with a stiff brush. Or put in the weldment 15 ~ 20 ℃ mass fraction of 10% nitric acid solution, dip 10 ~ 20min.3, washed in hot water washing weldment.4, the weldment or drying with hot air drying oven at 100 ℃ for var addthis_config = {"data_track_addressbar":true};

cleanup work before welding aluminum weldingWelding aluminum requires the cleanest preparatory work, otherwise its corrosion resistance decreased, but prone to porosity. Welding aluminum welding steel habits should be completely separate. Welded steel tools have been used, the use of non-welded Gas Shielded Welding Wire aluminum. Trimming region oxide film impurities, try to use stainless steel brush or cleaned with acetone. Grinding wheel can not be used, because the use of grinding wheel will only make the surface oxide film is fused in the welding consumables, without actually removing. If the wheel and rigid, one of the impuritiesWill enter the weld, causing thermal cracking. Further, since the Al2O3 film in a very short period of time will regenerate and stacked, the oxide film in order to influence as little as possible weld should be cleaned immediately after welding. var addthis_config = {"data_track_addressbar":true};
