The main difficulty, appearing in solution of the problem of automatic «tracking» the line of joint welded in tandem arc welding, is connected with measurement of side deviations from this line of each of electrodes located close to each other in the process of welding. Besides, together with side correction of movement of the electrodes, deviating from the line of joint welded, a need in angular correction of a torch is appeared, which could provide «parallelism» between the line of joint welded and the line, connecting the electrodes. A new approach to the solution of the above-mentioned problem was proposed, based on application of electric arc methods of measurement and application of recurrent procedures of linear and angular correction of the welding torch movement. The results of computer modeling are given in the paper. 8 Ref., 3 Figures.
