Abstract:
1. A method for electroslag welding a first work piece and a second work piece comprising: arranging a first surface of the first work piece spaced apart from a second surface of the second work piece; securing a first side member, a second side member and a base member adjacent to the first surface and the second surface to form a void between the first work piece, the second work piece, the first side member, the second side member and the base member; placing a wire guide in the void; providing a flux material in the void and adjacent to the wire guide; placing a first electrode through a first opening in the wire guide; placing a second electrode through a second opening in the wire guide; passing an electrical current through the first electrode to form a molten slag from at least a portion of the flux material; feeding the first electrode into the molten slag at a first feed rate; feeding the first electrode into the molten slag at a second feed rate; corresponding to the feeding of the first electrode at the first feed rate, feeding the second electrode into the molten slag at a feed rate equivalent to the second feed rate; and corresponding to the feeding of the first electrode at the second feed rate, feeding the second electrode into the molten slag at a feed rate equivalent to the first feed rate, wherein the feed rates of the first electrode and the feed rates of the second electrode alternate with respect to each other over time facilitating an alternating pattern of feeding the first electrode and the second electrode.
