Abstract
Application of automatic and robotic welding systems in modern welding fabrication requires development of algorithms for welding mode parameter control, namely parameter assigning and adaptive correction, depending on conditions. In addition to the main parameters of welding mode (welding current, voltage, speed) and groove geometry, electrode extension and shielding gas composition also have their effect on parameters, determining weld formation and effectiveness of using arc thermal energy for welded joint formation. Dependences of bead cross-sectional area and total thermal efficiency of welding process on electrode extension and shielding gas composition were experimentally established. These dependences were taken into account when improving the earlier developed procedure for calculation of welding mode parameters. Equations take into account both the technological parameters (groove angle, electrode position in the groove, welding speed), and shielding gas composition and electrode extension. 7 Ref., 2 Figures.
