Almost all kinds of welding methods can be used to weld aluminum, but aluminum has different adaptability to various welding methods, and various welding methods have their own application occasions.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 for the repair welding of aluminum alloy castings.The inert gas shielded welding (TIG or MIG) method is the most widely used welding method for aluminum and aluminum alloys.Aluminum and aluminum alloy sheet can be tungsten arc welding or tungsten pulse argon arc welding.The thick plate of aluminum and aluminum alloy can adopt tungsten poly-helium arc welding, argon-helium mixed tungsten poly-gas welding, fusion poly-gas welding and pulse fusion poly-gas welding.Fusion gas arc welding and pulse fusion gas arc welding are more and more widely used (argon or argon/helium mixture).

1. Low-temperature M51 welding with m51-f wire is operated at a working temperature of 179 degrees, which has good compatibility for welding materials. It is mostly used for welding under extremely strict deformation control requirements or extremely thin conditions.

2. WE53 low temperature weld for seven series of aluminum alloy welding, welding working temperature at 380-400 degrees, is don't need any auxiliary when welding flux welding, thus preventing some solder residue in the process of welding, and welding strength is very high, can solve 3 series aluminum alloy and casting, welding or die casting.

3. Q303 low-temperature aluminum welding wire also has some special advantages for aluminum alloy weldability, that is, narrow gap welding with bad Angle.
