magistrsko delo
Abstract
Magistrsko delo je bilo osredotočeno na preučevanje obločnega varjenja čepov s
konstrukcijskim jeklom. V preiskavi so bili uporabljeni visokotrdnostni varilni čepi oz. vijaki
razreda 8.8, katerih varivost smo preverili skozi uporabo vizualnega ocenjevanja, mehanskih
preizkusov, kamor spadata upogibni in natezni preizkus, makro preiskav in meritev trdot. V
nalogi smo želeli ugotoviti, ali je trenutni postopek varjenja, ki ga uporabljamo v podjetju Preis
Sevnica, d. o. o., primeren za varjenje čepov iz tovrstnega materiala. Če je odgovor ne, potem
smo želeli izboljšati postopek v tej smeri, da bi se lahko na zvarjenih čepih izognili dodatnemu
(preventivnemu) pretaljevanju zvara s postopkom TIG. V magistrskem delu bom predstavil
celotno raziskavo, ki se je začela s preučevanjem varilnih standardov, člankov in materialnih
lastnosti, končala pa z analiziranjem podatkov, pridobljenih iz eksperimentalnega dela, ter
zbranih zaključkov.

Secondary title: |
Arc stud welding on low alloy construction steel |
Secondary abstract: |
The master's thesis was focused on study of the arc welding of studs on construction steel.
High-strength welding studs of class 8.8 were used in the study, the weldability of which was
verified trough the use of visual inspection, hardness test, mechanical tests such as bend and
tensile test. In the thesis, we wanted to determine whether the current welding procedure used
by the company Preis Sevnica, Ltd., is suitable for welding studs of this type of material. If no,
then we wanted to improve the procedure in direction to avoid additional (preventive)
remelting of the weld by TIG process. In the master's thesis, I will present the entire research,
which began with the study of welding standards, articles and material properties and ended
with the analysis of obtained data from experimental work and collected conclusions. |
