WELDING OF STEEL STRUCTURES

Diplomska naloga opisuje potek in razvoj varjenja skozi zgodovino.Predstavljena sta delitev in označevanje konstrukcijskega jekla v gradbeništvu.Prikazani so grafični simboli označevanja ter opisane so izvedbe in uporaba kotnih, čelnih in čepastih ter zvarov z zaobljenimi robovi.V nadaljevanju so opisani postopki varjenja z mehansko, električno in kemično energijo. Kot zadnje so opisane napake v zvarih in zagotavljanje kakovosti z različnimi metodami testiranja zvarov.The thesis describes the course and development of welding throughout history. It describes the division and labelling of structural steel in construction. It also presents the graphic symbols for labelling and describes the procedures and use of corner, butt and slot weld and welds with rounded edges. In continuation the thesis describes welding procedures using mechanical, electrical and chemical energy. At the end, the thesis presents welding defects and quality assurance through different methods of testing welds
