Abstract

U teorijskome dijelu rada obrađeni su MIG/MAG postupak zavarivanja i stanice za robotizirano zavarivanje istim postupkom. Opisani su načini prijenosa metala u električnome luku, a posebna pozornost posvećena je prijenosu metala impulsnim lukom. Također, opisani su osnovni dijelovi robotske stanice za MIG/MAG zavarivanje uključujući i sustav za čišćenje pištolja, a dan je i pregled senzora koji se upotrebljavaju kod istih. Cilj eksperimentalnoga dijela rada bilo je utvrđivanje optimalne varijante prijenosa metala na temelju rezultata zavarivanja tri ispitna uzorka. Određeni su parametri procesa i izrađeni su programi za zavarivanje svakoga pojedinoga uzorka. Na kraju rada izvršena je analiza dobivenih rezultata i doneseni su zaključci sukladno tome.

Abstract (english)

The theoretical part of the thesis deals with MIG/MAG welding process and robot welding stations applying the same procedure. Modes of metal transfer are described, with special attention being given to pulsed spray metal transfer. Also, the basic configuration of MIG/MAG robotic welding station is described, including a torch cleaning station, and a review of the sensors used within are given. The aim of the experimental part of the thesis was to determine the optimal variant of the metal transfer mode based on the results given from welding of three test samples. Process parameters were defined and welding programs for each individual sample were created. At the end of the paper, an analysis of the obtained results was made and conclusions were drawn accordingly.
