description: The aim of the work is to design a model of a transistor inverter DC power source for non-consumable electrode welding of copper plates up to 6 mm thick in a helium environment. In the course of the work, the following tasks are performed: 1.Investigation of the process of welding with a non-consumable electrode in a helium medium of metal structures and welding properties of copper 2.simulation of the process of welding copper plates up to 6 mm thick in helium environment, determination of the key parameters of the welding process 3.Selection of the optimal power source circuit for welding copper plates of the selected thickness 4.Construction and calculation of the transistor inverter DC power supply circuit 5.analysis of the results obtained In the course of the work, programs such as "Matlab Simulink" and "Comsol Multiphysics" were used. In the program "Comsol Multiphysics" a model of the welding process of copper plates in a helium environment was built, in the program "Matlab Simulink" a diagram of the power source of the welding torch was made. As a result of the work performed, a two-dimensional model of a transistor inverter source was obtained, which provides an uninterrupted supply of energy to the welding torch. This model very accurately reflects real electrical processes and takes into account the features of the task assigned to it.
