Abstract

PURPOSE: To prevent occurrence of defective fusion and realize high efficiency welding, by disposing the succeeding electrode at a specified distance from the preceding electrode, and setting the current and voltage of the succeeding electrode higher than those of the preceding electrode by specified values.
CONSTITUTION: The distance 3 between a preceding electrode 1 and a succeeding electrode 2 is determined so that the succeeding electrode may be positioned at a distance where part of molten metal by the preceding electrode 1 starts to solidify. The electrode 1 continues to preheat while digging a base metal 4, and the produced molten metal 5 is blown in the direction of arrow 6, and part of the molten metal rapidly solidifies in part 7. The succeeding electrode 2 generates force in the direction of arrow 8 and prevents the molten metal 5 from being blow in the direction of arrow 6, and remelts the rapidly solidified part 7 including defective fusion part, thereby forming a sound bead. For this purpose it is essential to keep the arc length sufficiently long by setting the current range of the electrode 2 about 1W1.8 times of the current of the electrode 1 and the voltage of the electrode 2 higher than the voltage of the electrode 1.
