| 主权项 | 1. A twin wire welding apparatus comprising: a first contact tube for guiding a first consumable electrode toward a weld puddle and for transferring welding current to the first consumable electrode; a second contact tube for guiding a second consumable electrode toward said weld puddle and for transferring welding current to the second consumable electrode; a single power source connected to said first and second contact tubes for providing a same potential to said two consumable electrodes; and a feeding arrangement for feeding a cold wire into said weld puddle, said arrangement configured to feed said cold wire essentially orthogonally into said weld puddle. | ||
