This diploma thesis deals with the design and virtual commissioning of a robotic welding workplace for a given component. The theoretical part of the thesis is focused on research in the field of virtual commissioning and industrial robotization. Furthermore, the basic knowledge in the field of arc welding is described. In the system analysis, the selection of the concept and composition of the robotic workstation is discussed. The selected variant is developed in the form of a 3D model of the individual components. The practical part describes the design of the model in the simulation environment Process Simulate, the creation of the PLC control program in the software TIA Portal and the creation of robotic programs in the software RobotSt...
