Electroslag welding of 75 to 100 ton ingotsA new process for joining large cross-section components by electroslag welding is reported that utilizes four consumable electrodes made of the same material as the ingots. A bifilar current supply provides the very large energy input to the consumerable nozzle for heating the ingots being welded. This process produces better and more homogeneous mechanical properties, better chemical composition and structure uniformity, and requires no prior or simultaneous heating of ingots during welding. It is now possible to obtain medium size ingots and join as many as are required to produce 500 or 600 ton ingots.
