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.
Claims2
In an apparatus for electroslag welding of steel sheets with the aid of at least one wire electrode pair, a welding gap being defined between the electrodes of said electrode pair, current-carrying means for the electrode pair, and supply means for supplying metal in a powdered state, and welding powder into said welding gap,
- the improvement comprising:
- shielding means creating an elongated area along said current-carrying means, said elongated area, owing to the shielding means, being substantially free of any magnetic field, and wherein said supply means includes at least one supply tube positioned in said elongated area.
