In the paper special attention is given to application of pulsed-arc tandem welding by coated electrodes. Mock-ups of equipment for tandem welding and surfacing were developed and studied. A scheme was proposed for tandem arc welding by stick coated electrodes, fitted with capacitive energy storage devices, as well as a device-attachment that allows using any welding current source to perform this kind of welding operations. The attachment operation is based on the principle of controlling the electrode melting rate that ensures their uniform mutual burnout. Also shown are time diagrams, which clarify the principle of operation of the device, photos of surfaced samples, oscillograms of currents supplied to the welding electrodes. 7 Ref., 8 Fig.
Keywords: tandem arc welding, capacitive energy storage devices, pulse-time regulation of electrode melting rate
