Welding method:
Almost all kinds of welding methods can be used for welding aluminum and aluminum alloys, aluminum and aluminum alloy but with different adaptability to a variety of welding methods, various welding methods have their respective applications. Gas welding and arc welding methods, devices, simple and easy to operate. Welding can be used for less demanding welding quality aluminum sheet and castings welding. SMAW welding aluminum alloy castings can be used. Inert gas welding method is the most widely used method for welding aluminum and aluminum alloys. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Aluminum and aluminum alloy plate can use tungsten arc welding helium, argon-helium mixed gas tungsten arc welding, MIG welding, pulsed MIG welding. MIG welding, pulsed MIG welding is widely applied, before welding preparation.(3003 h14 aluminum)
Clean up before welding:
1, aluminum and aluminum alloy welding, welding should be strictly removed before oxide film and the oil and the workpiece weld wire surface; clean up after such long time storage, reprocessing.(aluminum floor plate sale)
2, plate: aluminum at low temperature strength, good flow properties of liquid aluminum weld metal during welding prone to staying phenomenon. In order to ensure penetration but will not collapse, welding often used to hold the plate and around the metal bath. Pad can be graphite plate, stainless steel, carbon steel, copper, or copper and the like. Surface of the pad to open a circular grooves, in order to ensure that the weld negative shape. May not add side welding plate forming, welding operation but requires skilled arc welding or take strict energy automatic feedback control and other advanced technological measures.
3, preheat: thin, small pieces of aluminum generally do not preheat thickness 10 mm ~ 15mm preheat time can be, depending on the type of aluminum alloy preheating temperature can be 100 ℃ ~ 200 ℃, available oxygen a acetylene flame, furnace or other heating blowtorch. Preheat weldment can reduce distortion, reduce porosity and other defects. After the welding process.(aluminum alloy 5052)
Stay clean up after welding and seam welding in the vicinity of the residual flux and welding slag will destroy the aluminum surface passivation film, sometimes corrode aluminum parts, should be cleaned. Simple shape, the general requirements of the workpiece can be a simple way with hot water or steam blowing scouring brush to clean. Demanding and complex shape of aluminum parts in hot water after brushing with a stiff brush, and then at about 60 ℃ ~ 80 ℃, concentration of 2% to 3% aqueous solution of chromic acid or potassium dichromate solution immersion 5min ~ 10 min, and scrub with a stiff brush, then washed in hot water washing, drying oven or with hot air drying, can also be dried naturally.
Post weld heat treatment of aluminum containers generally do not require post-weld heat treatment.
