Abstract
PURPOSE: To automatically perform good melt-sticking free from any defect such as lack of fusion by plastically deforming a consumable electrode into waveform and directing the tip thereof alternately toward a pair of welding work sides.
CONSTITUTION: A consumable electrode 19 out from a guide 18 is meshed with the tooth parts 22 of feed rollers and is further fed into a guide cylinder 20. At the instant when its tip passes through the guide cylinder 20, the operation of feed roller driving motors is stopped for a moment. The consumable electrode 19 is plastically worked to sigzag waveform by the meshing with the tooth parts 22. After this, the guide cylinder 20 is inserted into a narrow groove part 26 and an arc 33 is generated between the consumable electrode 19 and the members to be welded 24, 25; at the same time, the guide cylinder 20 is moved at a constant speed along the narrow groove part 26 and further the consumable electrode 19 is fed into the cylinder 20. A pair of the members 24, 25 are progressively welded via a melt- sticking part 34, and since the tip of the electrode 19 is of waveform, it directs alternately to the members 24, 25 sides along with its consumption, thereby forming the good meltsticking part 34 free from any welding defect such as lack of fusion.
