The slag may be introduced either molten or as dry powder. The workpieces are preferably pre-heated, e.g. by induction. As shown, a metal trough 4 is surrounded by an AC.-connected, induction heater coil comprising a water-cooled serially-wound conductor 7 having stacked turns and insulated, e.g. by tape, from a trough coil support plate 5. Water-cooled melt-retaining shoes 12 are mounted on the ends of the trough. In operation, the coil 7 is energized and molten slag is passed into the trough. The slag may include oxides of silicon, calcium, aluminium, manganese, magnesium. Spaced, A.C. connected, consumable electrode wires 14 (e.g. of nickelchromium alloy) are motor-fed down into the molten slag through consumable guides 16 which are stood away from the workpieces by consumable insulating bobbins 17, e.g. of the same material as the slag. As the molten pool and overlaying slag rises, further water-cooled shoes 12 are progressively stacked. On weld completion, the underlying trough and surface irregularities are machined off. For non- rectangular workpieces, e.g. circular shafts, rectangular-section, circularly-apertured, adapter checks are welded over the workpiece ends and the trough placed beneath the checks, the latter being post-weld removed along with the trough. In Fig. 3 (not shown), the slag is heated by a resistance heater rod, e.g. of carbon, which, together with spaced insulating supports (e.g. of asbestos), is positioned in, and lengthwise of a channel-section trough.
