    Abstract: A method of repairing defect in cast iron workpiece, including: machining the workpiece in the area of the defect to remove the defective material and form a chamber opening at a surface of the workpiece; anchoring a receptacle to the workpiece above the chamber (2), the receptacle is provided with an orifice in communication with the chamber; adding molten iron (4) into the receptacle so that it at least part of it flows into the chamber; adding slagging agent (5) into the receptacle; heating the slagging agent and the molten iron with an electrode (6); adding nodulizing agent into the molten iron so as to segregate graphite; and allowing the molten iron and the workpiece to cool down slowly. The above-described technique also has applicability for connecting two cast iron workpieces (11, 12) together.

    Abstract: The invention is a consumable guide tube comprising a thin first elongated strip, a second elongated strip and a plurality of insulators. The thin first elongated strip has a front face and a back face and the front face has at least one longitudinal channel. The second elongated strip has a front face and a back face and the front face of the second elongated strip is configured to be coupled to the front face of the thin first elongated strip. The plurality of insulator modules are deposited on the back face of the thin first elongated strip and on the back face of the second elongated strip. Preferably, the thin first elongated strip is a low carbon cold rolled steel strip, and the second elongated strip is a low carbon hot rolled steel strip. The guide tube can also be configured to comprise two or more longitudinal channels.

    Abstract: A method of fabricating a structural member such as a wicket gate for water turbines by electro slag forming comprises the steps of mounting a water-cooled metal mold on a part of a previously formed structural member, such as a stem; melting electrodes inserted in the water-cooled metal mold to form the other part of the structural member such as a vane portion of the wicket gate on the previously formed structural member. The previously formed structural member has a concave portion which is exposed in the water-cooled metal mold and the water-cooled metal mold is mounted so as to contact with the previously formed structural member at the lower portion than the top of the concave portion. The previously formed structural member is melted gradually from the central portion of the concave to the outer periphery and then such a portion as the vane portion is formed by molten metal of the electrode.

    Abstract: In an apparatus for electroslag welding of steel sheets with the aid of at least one wire electrode pair, a welding gap defined between the electrodes of the electrode pair, current-carrying conduits for the electrode pair, and a supply tube for supplying metal in a powdered state, and welding flux into the welding gap, the improvement includes a shielding device creating a duct along the current-carrying conduits. The duct, owing to the shielding device, is substantially free of any magnetic field, and the supply tube is positioned in the duct.
