In the introductory part of the thesis, hybrid welding is described and an overview is presented of the best-known hybrid welding processes, general characteristics of hybrid processes and their application. In addition to the previously mentioned, the TIG and MIG welding process is described - the principle of operation is presented, advantages and disadvantages of the process, power sources used by said processes, equipment for TIG and MIG welding and the torches used in such welding. Shielding gases are described in TIG and MIG welding and the application of the mentioned welding processes. After that it is the diagram of the TIG+MIG hybrid process is shown - its working principle, advantages and disadvantages, creating an electric arc, torches for the TIG+MIG welding process and its application. In the experimental part of the work, welding was performed on an aluminum plate (basic material - AlMg3), an additional material of AlMg4.5Mn0.7 was used. They are shown current sources used in the experiment as well as welding parameters and shielding gases. The MIG syncropulse welding process is described and its parameters are presented.
