• Zavarivanje i zavarene konstrukcije, Semester 1, position 1

The aim of this course is to introduce students to different types of engineering materials and their properties with the goal of understanding and studying the possibility of their application for manufacturing of different elements and constructions. Special attention is devoted to studying the influence of composition, thermical proccesing and processing by plastic deformation on the structure and properties of the material. This course enables possible collabortions with institutes, companies and factories that make and construct engineering materials and deal with their application.

Upon the successful completion of the course, students are able to: - solve specific problems in the fields of detecting and recognizing damages in metallic structures and welded joints in particular; - determine the potential causes of damage; - perceive the eventual possibilities for preventing the occurrence of damage; - define the testing programme for detecting damages in mechanical structures; - prescribe maintenance measures for preventing damage in mechanical structures; - relate the acquired knowledge to other fields, with practical applications.
