The entire system is controlled by a fully digital system, meaning that no analog components are present, and only digital signal processing (DSP) methods are used. This configuration provides full control over the parameters, eliminates disturbances caused by environmental influences, and allows for smooth robot movements thanks to the fast response of the bus. All of these factors contribute to achieving consistent welding results. Another key component is the welding power source. The discussed station utilizes a Fronius MagicWave 4000 model power source. This digitally controlled module supports two welding methods, TIG AC/DC and MIG, characterized by a stable arc. It has an output of 400A. This power source can weld aluminum alloys, low and high alloy steels, and non-ferrous metals. 3. Welded Structure The door frame for rail vehicles has been designed in accordance with functionality requirements and standards, with each section of the panel needing to meet specific strength parameters [13]. During the design phase, each joint is analyzed, and the appropriate type of joint and weld is selected. According to the requirements of EN-15085-3, the
