Welding method almost all kinds of welding methods can be used for welding aluminum and aluminum, but aluminum and aluminum alloy adaptable for different kinds of welding methods, various welding methods have their own applications. Gas welding and arc welding method for producing aluminum products processing price, simple equipment, easy to operate. Welding can be used for less demanding welding quality aluminum sheet and castings welding. SMAW can be used for welding aluminum alloy castings. Inert gas welding (TIG or MIG) is the most widely used method of aluminum and aluminum alloy welding methods. Aluminum and aluminum alloy sheet can be tungsten or tungsten AC TIG pulse welding. Aluminum and aluminum alloy plate can be tungsten arc welding helium, argon-helium mixed gas tungsten arc welding, MIG welding, pulsed MIG welding. MIG welding, pulsed MIG welding is widely applied (argon or argon / helium mixture) 2) mechanical cleaning: the workpiece size is larger, longer production cycle, multi-layer welding or chemical cleaning When and contamination, often using mechanical cleaning. With acetone, gasoline and other organic solvents to wipe the surface of the oil, followed directly with a diameter of 0.15 mm ~ 0.2 mm copper wire brush or steel wire brush aluminum products processing parts, brush onto the exposed metallic luster so far. Generally should not use the wheel or ordinary sandpaper, in order to avoid sand left on the metal surface, into the bath defects such as slag generated during welding. There is also available scraper, rasp and other clean-up surface to be welded. After clean-up, such as storage periods of time (such as more than 24 h) should be re-processed.
