Abstract

898,151. Welding by fusion. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 3, 1960 [Oct. 6, 1959], No. 33838/60. Class 83 (4). In carbon dioxide shielded arc welding using two consumable electrodes 8, 9 in tandem, the electrodes are insulated from one another and are each connected to a direct-current source and their tips are separated by a distance such that the depressions 11, 12 in the weld pool produced under the welding arcs 14, 15 are separated by a dam 16 of liquid weld metal. The electrodes 8, 9 which may be round or flattened in section are fed through insulated guides 6, 7 surrounded by a common gas nozzle 10 having a cross-section made up of two equal semicircles centred on the electrodes and joined by their common tangents. The spacing of the electrodes 8, 9 is at most equal to twice the radius of the semicircles and is greater than that radius. Thus, with a radius of about 7.5 mm. and an electrode diameter of 1.5-2 mm. the spacing is 8-15 mm.
