Subject aims expressed by acquired skills and competences
The aim of the course is to:
• Provide students with deeper knowledge of the physical principles of modern welding, brazing, and material cutting methods.
• Familiarize students with technological parameters, adjustment options, and process control.
• Teach students to evaluate the suitability of individual methods for specific applications.
• Develop the ability to assess the quality of welded joints and identify possible defects.
• Prepare students for the practical application of these technologies in industrial practice.
Special welding methods include, for example: plasma welding, electron beam welding, laser welding, electroslag welding, ultrasonic welding, diffusion welding, explosion welding, aluminothermic welding, friction welding, welding with flux-cored electrodes, electrogas welding, electric arc stud welding, metal cutting by plasma, laser and water jet, flame gouging, and carbon arc gouging.

Summary
The graduate of the course acquires comprehensive knowledge of the theoretical foundations, technological principles, and industrial applications of modern methods of welding, brazing, and material cutting. They are familiar with a wide range of advanced technologies, such as plasma welding, electron beam welding, laser welding, electroslag welding, ultrasonic welding, diffusion welding, explosion welding, aluminothermic welding, friction welding, as well as various cutting and gouging methods. They understand the physical principles of individual processes, the design of equipment, and the selection of technological parameters. They are able to assess quality control aspects, economic efficiency, and the possibilities of automation and robotization of production processes. The acquired knowledge is applied in comparing and selecting suitable technologies with regard to specific materials, thicknesses, and operating conditions, including demanding applications, for example in the energy sector.
