20.500.12556/RUL-108760 Emisije delcev prahu nastalih pri varjenju nerjavnega jekla Emissions of the dust particles arrised at non-ferrous steel welding Pri varjenju se sproščajo dimni plini, ki škodljivo vplivajo na zdravje delavcev. Dimni plini so različne mešanice plinov in drobnih delcev, ki pri vdihavanju ali zaužitju predstavljajo tveganje za zdravje delavcev. Stopnja tveganja je odvisna od sestave in koncentracije delcev prahu ter trajanja izpostavljenosti. Sestava je odvisna od osnovnega materiala, varilnega postopka in dodajnega materiala. V okviru diplomskega dela so izvedene meritve emisij delcev prahu pri ročno obločnem varjenju nerjavnega jekla z oziroma brez uporabe odsesovalne naprave. Vzorčenje je bilo izvedeno z uporabo osebnega merilnika za vzorčenje EGO PLUS TT. Sestava in geometrija delcev prahu zbranih na filtrih sta bili analizirani v skladu s standardom ISO 13322 z uporabo vrstičnega elektronskega mikroskopa. During welding procedures a lot of gases are emitted into the air, which can damage the health of the workers. Gases have different compositions and contain dust particles, which can provoke certain risks when inhaled by the workers. The degree of risk depends on the composition, concentration and time exposed to the harmful gases. Composition of gases depends on usage of different welding procedures, basic material and electrode. The idea of diploma work was to measure the emission of dust particles during manual arc welding of stainless steel with the usage and without the usage of ventilation device. Filtration of dust particles was conducted by EGO PLUS TT device. Composition and geometry of dust particles were examined according to the standard ISO 13322 using scanning electron microscope. delec prahu emisije nerjavno jeklo ročno obločno varjenje vrstični elektronski mikroskop (SEM) analiza delcev prahu dust particle emission stainless steel manual arc welding scanning electron microscope (SEM) analysis of dust particles true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-07-20 07:45:02 2019-07-20 07:45:17 2022-08-20 03:48:19 0000-00-00 00:00:00 2019 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 67879 1818463 4133.pdf 4133.pdf 1 6B3CFA09CC28B4C10A128286015486CC 4a8268a19004fa5f75a883e58791aea45089d1b161877e45e22fa778f08433db b66a9b34-a1b6-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=119789 Naravoslovnotehniška fakulteta 0 0 0
