Abstract

Tehnologija zavarivanja jedna je od najvažnijih tehnoloških procesa u metalnoj industriji. Kako tehnologija ide u korak s vremenom, tehnologije se sve više kombiniraju. Prema tome se i u tehnologiju zavarivanja često se implementiraju druge tehnologije, u ovom konkretnom završnom radu promatrat će se implementacija robotike, odnosno robotizacije, u tehnologiju zavarivanja. Takvim kombiniranjem dvaju navedenih tehnologija dolazi do razvoja nove tehnologije pod nazivom robotizirano zavarivanje. Jedan od najčešće robotiziranih zavarivačkih postupaka je MAG postupak zavarivanja. Također senzori imaju značajnu ulogu pri robotiziranom zavarivanju. Senzori služe za kontrolu, praćenje putanje zavarenog spoja. U prvom, teorijskom, dijelu rada razrađuje se tema robotiziranog MAG zavarivanja, senzorima koji se primjenjuju kod robotiziranog MAG zavarivanja te njihovim značajkama, ograničenjima i primjeni u svakodnevnoj proizvodnji, industriji. U eksperimentalnom dijelu definiraju se parametri senzora električnog luka koji omogućuju praćenje putanje zavarenog spoja, prati se korekcija putanje zavarivanja pomoću senzora, pri mijenjanju parametara. Na kraju rada iznesen je zaključak na temelju rezultata ispitivanja.

Abstract (english)

Welding technology is one of the most important technological processes in the metal industry. As the technology keeps pace with time, technologies are more often combined together. Accordingly, many technologies are often implemented in the welding technology, as well,in this practicular thesis, the implementation of robotics, or robotization, will be considered. By combining these two technologies, a new technology called robotic welding is beeing developed. One of most commonly robotised welding processes is the MAG welding process. Sensors also have a significant role in robotic welding. The sensors are usred for controlling and tracking the welded joint. In the first, theoretical part of the thesis, it is written about robotic MAG welding, and the sensors in robotic MAG welding, their features, limitations and applications in everyday production, industry. In the experimental section, the parameters of the through arc sensor which ennable tracing of welded joint are defined, also the correction of the welding path using the sensor is monitored, when parameters are changing. At the end of the work a conclusion was made based on the results of the research.
