Modalities of parametrization at modern TIG welding equipment

U teorijskom dijelu opisan je TIG postupak zavarivanja te potrebna oprema i parametri koji se koriste kod ove vrste zavarivanja. Detaljnije su objašnjene modificirane vrste TIG zavarivanja s naglaskom na impulsno i visokofrekventno TIG zavarivanje. U eksperimentalnom dijelu rada osmišljen je pokus kojim su se dokazale prednosti modaliteta podešavanja struje. Navareno je dvanaest uzoraka različitim parametrima zavarivanja. Ispitani su utjecaji određenih parametara na stabilnost procesa, produktivnost i geometrijske značajke zavara. Na dobivenim uzorcima provedena je analiza profila: zona utjecaja topline, penetracija, širina i oblik, te su međusobno uspoređeni i prikazani grafički i tablično. Temeljem dobivenih rezultata eksperimentalnog rada donesen je zaključak o primjenjivosti TIG postupka zavarivanja i njegovih inačica.The theoretical part describes the TIG welding process and the necessary equipment and parameters used in this type of welding. Modified types of TIG welding are explained in more detail with emphasis on pulsed and high-frequency TIG welding. In the experimental part of the paper, an experiment was devised which proved the advantages of the current adjustment modality. Twelve samples were welded with different welding parameters. The influences of certain parameters on process stability, productivity, and geometric characteristics of welds were examined. On the obtained samples, the analysis of the profile was performed: heat affected zone, penetration, width, and shape, and they were compared and presented graphically and tabularly. Based on the obtained results of the experimental work, a conclusion was made on the applicability of the TIG welding process and its variants
