Title:
GAS-SHIELDED ARC WELDING SYSTEM AND GAS-SHIELDED ARC WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/187981
Kind Code:
A1
Abstract:
A plurality of welding torches (21A, 21 B), which are disposed in a welding device and are made movable in three-dimensional directions, are provided with welding wires (23A, 23B) that differ in composition and diameter from each other. When welding is performed in the horizontal direction, an arc (31) is generated by at least two of the welding torches (21A, 21B) to form a bead while the welding wires (23A, 23B) are being fed. When welding is performed in the vertical direction, the arc (31) is generated by any one welding torch (21B) of the two welding torches (21A, 21B) to form a bead while the welding wire (23B) is being fed. Thus, a steel sheet to which an anti-corrosion material has been applied can be welded continuously with high quality and high-efficiency in a horizontal orientation and vertical orientation.
