Course detail

Special Welding Technology

FSI-HSV Acad. year: 2023/2024 Winter semester

The special methods of fusion welding. The course deals with the technology of welding by high-power sources such as plasma, electron-beam and laser applications. It familiarises students with technological methods of thermal spraying and their industrial application. Special welding methods, stud welding. The special methods of pressure welding. Friction welding, explosion welding and diffusion welding. Metal 3D printing methods. Soldering of metals.

Learning outcomes of the course unit

Students will acquire knowledge of unconventional types of modern welding technologies, and will be able to apply these technologies to particular examples of special welding. They will be able to independently and creatively work on a welding procedure.

Prerequisites

Students are expected to be familiar with the fundamentals of fusion and pressure welding technology, as well as with science of materials.

Planned learning activities and teaching methods

The course is taught through lectures which are focused on basic principles and theories of the individual sectors. The teaching is completed by practical laboratory exercises.

Assesment methods and criteria linked to learning outcomes

The course-unit credits award is based on attendance at seminars, correct elaboration of computational assignment and active participation in its processing.

The final exam will be composed of written and oral part.

It is classificated to the ECTS grading scale.

Language of instruction

Czech

Aims

The main objective of the course is to provide students with the theoretical foundations and methodology necessary for solving technologies of problems relating to the application of special welding technologies. Students will acquire knowledge necessary for a complex solution of special welding technology application.

Specification of controlled education, way of implementation and compensation for absences

The attendance to the seminar is regularly checked and the participation in the lesson is recorded. The missed lesson a student will elaborate the complemental task.
