How can argon arc welding welding aluminum plate?
Argon arc welding, that is, arc welding plus argon gas protection.
Is the argon arc welding with argon as the gas protection welding, melting pole argon arc welding (MIG) and non melt pole argon arc welding (TIG welding), aluminum can only use the AC argon arc welding machine, gas with 4 9 argon; DC argon arc welding machine can also be used, but is the only reverse welding machine (the torch is connected with the cathode of tungsten), but the capacity is relatively large, can be welded solid, but relatively poor weld formation.
Thin aluminum sheet shall be AC welded by TIG. The thick ones can be welded by MIG
1, AC argon arc welding machine is selected. It has the function of cathode breaking.2 choose the right current3, pay attention to the temperature of the bath, the parent material does not melt, welding wire will roll to roll.4 the welding wire should be directly added into the bath5 the end of the welding wire should be protected by argon gas
