ABSTRACT
Application of narrowed grooves is an effective method to increase welding process efficiency at simultaneous reduction of financial and energy expenses. One of the main difficulties in implementation of multi-pass welding technology 10 mm thick rolled metal structures using automated and robotized units is a high possibility of defect formation such as lack of penetration, in particular, in layer of the first pass (wall bead). Control of welding parameters determining heat input is one of the methods of penetration regulation. Dependencies between welding parameters in problem areas of the grooves and penetration depth were determined experimentally. On their basis the equations for determination of parameters of bead deposition at given coefficient of areas were obtained. These results became a part of algorithm development to control welding mode parameters in automated and robotized units.
