    摘要： An electroslag welding process is described for welding metal workpieces, in which a consumable electrode is melted by contact with a molten slag pool supported in contact with surfaces of the workpieces onto which the metal from the electrodes is deposited. According to the novel feature, the workpiece surfaces together form a horizontally extending groove and the consumable electrode is placed horizontally within the groove surrounded by flux and at a distance from the workpieces greater than that at which arcing to the workpieces occurs during welding, whereby the electrode is progressively melted by the molten slag pool along the length of the groove with the molten electrode metal collecting at the bottom of the slag pool to form a weld joining the workpieces.

    摘要： Welding electrodes are disclosed including an elongated ribbon or strip coated with insulating and fluxing material for closefitting insertion in a gap between conductive plates or other shapes to be welded. The width of the electrode strip is substantially the same as the thickness of the members to be joined, while the thickness of the electrode is substantially equal to the width of the gap so that the gap is substantially filled when the electrode is inserted endwise through the gap. Very little electrode length need be subsequently inserted into the gap as welding proceeds to compensate for flux coating displacement and gap clearances. The electrode is coated with a glasslike or ceramic fluxing material having (e.g. for welding steel) a melting point above 900* F. The coating is a strong dielectric at lower temperatures but exhibits fluxing characteristics when molten at higher temperatures. The dielectric flux can be applied by dipping, spraying or painting, or by applying a sleeve of woven, matted or wrapped glass or glasslike fibers.
