Release time:
2022-08-12
Almost all kinds of welding methods can be used for welding aluminum and aluminum alloy, but the adaptability of aluminum and aluminum alloy to various welding methods is different, and each welding method has its own application.
Almost all kinds of welding methods can be used for welding aluminum and aluminum alloy, but the adaptability of aluminum and aluminum alloy to various welding methods is different, and each welding method has its own application. Gas welding and electrode arc welding method, simple equipment, easy to operate. Gas welding can be used to repair welding of aluminum sheet and castings with low welding quality requirements. Electrode arc welding can be used to repair welding of aluminum alloy castings. Inert gas shielded welding (TIG or MIG) is the most widely used welding method for aluminum and aluminum alloys. Aluminum and aluminum alloy sheet can be tungsten AC argon arc welding or tungsten pulse argon arc welding. Aluminum and aluminum alloy thick plates can be tungsten helium arc welding, argon-helium mixed tungsten gas welding, fusion gas welding, pulse fusion gas welding. More and more applications of pulsed MIG welding (argon or argon/helium)
