Abstract
Robotization of gas-shielded consumable electrode arc welding provokes a series of problems. They are caused by necessity to equip welding robots with special sensing devices, which could communicate information on real process of arc welding to control system in very complicated for observation conditions. This work considers the possibilities of practical application of arc sensors, which in contrast to other sensing devices do not need special protection from light and heat flows, spattering of molten metal and intensive emission of fumes in measurement zone itself. Given are analytical relationships for numerical evaluation of welding tool deviation from joint line on the results of current measurements coming from the arc sensor. These relationships can be used for construction of algorithms of automatic correction of welding tool movement directly in process of arc welding. 29 Ref., 3 Figures.
