20.500.12556/DKUM-94376 Prehod iz pg na pf lego varjenja: kronološki pregled, analiza napak in iskanje rešitev diplomsko delo The transition from pg to pf welding: a chronological overview, failure analysis and search for solutions V diplomskem delu je obravnavan pojav zelpov v zvarnih spojih na strehah bivalnih enot. V okviru diplomskega dela je bil izveden popis napak na zvarih, določena njihova pogostost in lokacija ter opravljen upogibni preizkus. Za analizo zvarnega spoja so bili izdelani makro obrusi problematičnega vzdolžnega spoja. Pri tem so bili uporabljeni postopki vizualnega pregleda, mehanskega preskušanja in makroskopske analize. This thesis addresses the occurrence of defects in welded joints on the roofs of residential units in a manufacturing company. Within the scope of the work, a defect survey of welds was conducted to record their frequency and locations. A bend test was performed to assess the mechanical performance of selected joints, and macro sections of a problematic longitudinal weld were prepared to examine its geometry and execution. The investigation employed visual inspection, mechanical testing, and macroscopic metallographic analysis.
