WELDING AND WELDABILITY OF CU-ALLOYS

Tema ovog diplomskog rada je zavarivanje i zavarljivost Cu-legura. U radu će se opisati postupci zavarivanja Cu-legura i provođenje kontrole kvalitete nakon zavarivanja. U uvodnom dijelu opisano je općenito o bakru, njegov kemijski sastav, legure bakra, gdje se primjenjuje i problemi kod zavarivanja bakra. Prikazano je preporuka postupka zavarivanja s obzirom na leguru zavarivanja, opisani su pojedini postupci zavarivanja legura bakra, primjena dodatnog materijala i kontrola kvalitete zavarenog spoja. Opisane su moguće greške prilikom zavarivanja bakra te su opisane mjere za izbjegavanje nastanka tih grešaka.The theme of this graduate thesis is welding and weldability of Cu alloys. This paper will describe the welding processes of Cu alloys and the implementation of quality control after welding. In the introductory part, copper is generally described, its chemical composition, copper alloy, where copper is applied and copper welding problems are described. The welding procedure recommendation is show with respect to the some copper alloys, some methods of welding copper alloys have been described, and use of additional material and weld quality control are described. Possible faults during welding of copper and measures taken to avoid the occurrence of these faults are described
