Abstract

PURPOSE: To well stabilize arc in MIG welding by letting shielding gas flow out from a hollow welding wire.
CONSTITUTION: When sheilding gas 8 such as helium gas is flowed out from the hollow part of a hollow welding wire 6, an arc flame 9 concentrates at melt zone 11 and gouge out molten metal, thereby increasing the depth of penetration of weld zone. In addition, the potential in the central part of the arc is increased. When the shielding gas 7 such as Argon is flowed out from a nozzle 2, the surroundings of the arm flame 9 are perfectly shielded and the inclusion of air becomes difficult to occur. At this time, the shielding gases 7 and 8 vary in specific gravity and therefore they are difficult to mix with each other, thus high effect is obtainable with a small rate of gas flow.
