Abstract

PURPOSE: To form the weld zone having a superior mechanical property with a high welding efficiency without producing a bad bead by deoxidation product, by carrying out direct current gas shielded arc welding with shielding gas, core wire and more than two electrodes applied different welding current.
CONSTITUTION: On occasion of using two electrodes, the distance between the preceding electrode 1 and the succeeding electrode 2 is kept apart more than 100mm. Shielding gas mixed more than 30% of CO2 gas or less than 5% of O2 gas with inactive gas, such pure Ar gas or He gas etc., is used in the ratio of 15W100l/ min. at the electrode 1 and 0.6W1.6mmϕ of the core wire 12 and 100W500A of welding current, are used. Shilelding gas mixed 7.5W50% of CO2 or 1W10% of O2 gas with pure Ar gas or He gas, is used in the ratio more than 50kg/min. at the electrode 2. 3W6.4mmϕ of large core wire is used for the core wire 22 and 600W1500A of welding current is used. The deoxidation product 8 is not moved in fron of arc and the weld zne 7 havig a superior impact value, is able to obtain.
