abstract = "In this paper the possibilities of applying sensors based on filters with surface acoustic waves (SAW) for the detection of harmful products in welding processes are analyzed. This review discusses the sensing mechanism and configurations of the sensors. The principles of SAW sensors are considered with special emphasis on the application of conducting polyaniline nanocomposites as sensitive thin layers in sensors for the detection of CO, NO2, and COCl2. The literature suggests the use of In2O3 as a dopant for CO and NO2 detection sensors, and ethylenediamine and phenylenediamine in COCl2 sensors. The paper presents original results of modeling of sensors that are designed for detection of CO and NO2 for which there are experimental data in the literature. The results obtained based on this model are in excellent agreement with results from the literature, which shows the validity of modeling. Based on the developed modeling methods, calculations were done for sensors for the detection of these gases in which the structure was the surface of quartz. From these modeling results it can be concluded that the use of the quartz substrate provides better sensitivity. In addition, the quartz sensors are thermally stable., U radu su analizirane mogućnosti primene senzora u čijoj osnovi se nalaze filtri sa površinskim akustičkim talasom (PAT), za detekciju štetnih produkata u procesu zavarivanja. Objašnjeni su principi rada PAT senzora sa posebnim osvrtom na primenu elektroprovodnih polianilinskih nanokompozitnih materijala – polianilin/In2O3 i etilendiamin i fenilendiamin polianilinskih nanokompozita kao osetljivih tankih slojeva za detekciju CO, NO2 i COCl2. Prikazan je deo originalnih rezultata modelovanja PAT
senzora koji su namenjeni detekciji pomenutih gasova. Rezultati dobijeni na bazi sopstvenog modela poređeni su sa rezultatima iz literature. Pokazano je da se ovim na činom modelovanja može uspešno odrediti koncentracija štetnih gasova u okruženju.",
