Abstract
To stabilize a melting state of a filler material to improve welding quality when a worker performs welding while inserting the filler material into an arc in a double shield tig welding method.SOLUTION: In a double shield tig welding method, a welding torch WT including an inner nozzle 4 which jets an inner gas 7 and an outer nozzle 5 which jets an outer gas 9 is used and the welding torch WT is energized with a welding current Iw to generate an arc 3. A flow rate Fi of the inner gas is set according to an average value Iar of the welding current Iw. When a worker performs welding while inserting a filler material 10 into the arc 3, correction is made to reduce the set flow rate Fi of the inner gas.SELECTED DRAWING: Figure 1
