    Abstract: An electroslag welding method utilizing, as its heat source, the resistance heat created in a molten slag during passage of current therethrough, in which a consumable guide is disposed in an opening that is, the groove defined by parent metals for guiding a welding electrode and fixed relatively centrally of groove by means of solid pieces of a flux so as to preclude electric shorting occurring between guide and the groove faces of said parent metals, and then a welding electrode in the form of a ribbon is fed through said consumable guide from a reel of said welding electrode.

    Abstract: A method for joining the electrodes for electroslag remelting comprises arranging the electrodes in a feeding position in which they are fed downwardly one above the other relative to an ingot to be remelted and welding at least the core regions of the two electrodes together by subjecting them to currents of high intensity. An electrode feeding device comprises a vertical stand with first and second electrode holders on the stand which are independently vertically movable thereon. Each holder is insulated from the associated stand and from each other and from ground and it is provided with clamping means for clamping an electrode in a position in which its axis extends substantially vertically above the ingot to be remelted. During operation, the holders are moved vertically such that the electrode held by the uppermost holder is positioned into abutting contact with the top of the electrode held by the lowermost holder. The apparatus also advantageously includes a centering, packing and insulating ring which surrounds the space between the two abutting electrodes and which may advantageously be made with a funnel-shaped upper portion which may be filled with a slag.

    Abstract: In an electroslag welding method employing a steel plate electrode inserted into the gap between the opposing surfaces of the base metal to be welded, at least that portion of the inserted electrode extending into the gap, when the overall width of the electrode is in excess of 300 mm., is divided into plural equal width sections each having a width of less than 300 mm. All of the sections of each electrode are commonly electrically connected to one terminal of a source of welding current. The electrode may comprise two physically separate sections commonly interconnected electrically to one terminal of the source, or may comprise a single electrode having that portion extending into the welding gap divided into two sections with the two sections being physically united to each other by that portion of the electrode outside the welding gap.
