Method and apparatus for GMAW welding |
摘要 |
A method and apparatus of welding along a pass line on a steel workpiece, which method and apparatus comprises simultaneously feeding two welding wires in generally parallel relationship toward a workpiece with extended welding wires generally intersecting the workpiece at individual points spaced from each other a distance in the range about 3/16 inch to about 3/8 inch; then creating a separate arc between each of the wires and the workpiece; passing a single protective envelope of shielding gas axially along two welding wires simultaneously and around said two separate arcs extending between welding wires and the workpiece; and, causing relative movement between the two gas shielded welding wires and the workpiece in the direction corresponding to the desired pass line on the workpiece.
