Abstract
Delo obravnava področje ultrazvočne kontrole zvarnih spojev pri certificiranju varilcev. Varjenje MIG/MAG je najbolj pogost postopek spajanja jeklenih konstrukcijskih elementov v celoto. Čeprav je postopek enostaven in primeren za robotizacijo, še vedno velik delež varjenja v industriji opravijo certificirani varilci. Ultrazvočna kontrola je zelo razširjena in ima pomembno vlogo pri ugotavljanju kakovosti zvarov tekom postopka certificiranja varilcev. S samim preizkušanjem zvarov pred uporabo varjenih konstrukcij lahko občutno zmanjšamo kasnejše stroške vzdrževanja in popravil. Opravili smo neporušno kontrolo zvarov, ki sta jih izdelala dva različno izkušena varilca z različnimi varilnimi parametri. Kakovost zvarov smo raziskali z neporušno metodo ultrazvočnega preizkušanja. Ugotovili smo, da se kakovost zvara od varilca do varilca razlikuje, in da je pomembno, da se, z namenom zagotavljanja kakovosti varjenja, varilce ustrezno izobrazi in certificira.

| Secondary title: | Ultrasonic quality examiniation of welded joints |
| Secondary abstract: | This study is about ultrasonic examination of welded joints in testing of welders. MIG/MAG welding is one of the most common processes of welding steel structural elements. Even though this welding method is quite simple and appropriate to robotize, there is still needed many certified welders in the industry. Ultrasonic examination is widespread and has a big role in testing of welded joints during the process of certification of welders. Apart from that, we can reduce maintenance expenses by inspecting the welds with ultrasound before allowing the construction to be used in industrial environment. The tested welds were made by two different experienced welders who used different welding parameters. The quality of welds was inspected using non-destructive method of ultrasonic examination. It was concluded that quality of welds varies from welder to welder and that it is important that welders are properly trained and certified in order to ensure the quality of welding. |
