Electro-Gas Welding(EGW)

 Electro-Gas Welding(EGW)

EGW use gas as arc protection & weld spool via. Gas media. It is divided by the electro consumption and gas protection. Consume electro or non-consume electrode are shielding with shielding gas, oxides mixed gas, CO2 shielding gas, pipe style gas shielding is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied.
