description: The subject of the graduate qualification work is âDevelopment and research of working of transistor welding invertor DC source for TIG welding of aluminum plates with thickness of 4 mmâ. The given work is devoted to developing of welding invertor model and investigating of it modes of operation. Main points of this work are: 1. Modeling of TIG welding modes using COMSOL Multiphysics 2. Selection and calculation of elements of TIG welding source. 3. Developing of TIG welding source using Matlab/Simulink 4. Mathematical modeling of operations of developed source using Matlab/Simulink The work was carried out using the COMSOL Multiphysics and Matlab/Simulink software packages. In the COMSOL Multiphysics environment, 9 different modes were calculated, of which 3 are associated with changes in the argon supply rate to the welding area, 3 show the dependence of the parameters of the simulated system on changes in the arc current, and 3 illustrate the effect of the arc length on its potential. Then, using the Matlab/Simulink package, a model of a welding inverter was built, on which 9 experiments were conducted with different loads. As a result, the arc resistances of each of the modes were calculated, the power high-frequency transformer was calculated, and the output current and voltage of the welding inverter were obtained when operating in different modes.
