FIELD: technological processes, metal working. ^ SUBSTANCE: invention is related to electric arc welding and may be used in manual or automatic welding in machine building. Method of electric arc welding includes arc ignition between product and two parallel electrodes insulated from each other by coating layer. Electrodes are connected to welding DC generator through parallel-connected ballast rheostats. Electrodes are used, ends of which are located at the angle of 45 to product. ^ EFFECT: provision of possibility to use direct welding current of electric arc welding with two electrodes insulated from each other, with provision of permanent arcing between two electrodes and product. ^ 3 dwg |
