Abstract
Tema završnog rada obrađena je teorijski i eksperimentalno. U teorijskom dijelu naglasak je na MIG postupku zavarivanja te dvjema varijacijama postupka na temelju struje i vrste prijenosa metala, a to su AC MIG te DC MIG-P zavarivanje. Objašnjene su glavne značajke svakog te prednosti i mane svakog od njih. Također, kod aluminijskih legura EN AW 5083-H321 i EN AW 6082-T6 obrađen je problem njihove zavarljivosti te dodatnog materijala i plinova koji se koriste tijekom zavarivanja ovih legura. Naposljetku, sukladno zahtjevima norme HRN EN ISO 15614-2, opisan je fenomen pada čvrstoće u području zavarenog spoja. Eksperimentalni dio rada proveden je ispitivanjem tvrdoće metodom Vickers, opterećenjem HV5 na navedenim aluminijskim legurama te je kvantificirana širina područja zone utjecaja topline. Naposljetku, određen je relativni pad čvrstoće u području zavarenog spoja te je predložena primjena AC MIG postupka u izradi aluminijskih zavarenih konstrukcija.
Abstract (english)
The topic of the final paper was treated theoretically and experimentally. In the theoretical part, the emphasis is on the MIG welding process and two variations of the process based on current and metal transfer processes that arose from it, AC MIG and DC-MIG-P welding. The main features of each and the advantages and disadvantages of each are explained. Also, in the case of aluminum alloys EN AW 5083-H321 and EN AW 6082-T6, the problem of their weldability and the additional material and gases used during welding of these alloys was addressed. Finally, in accordance with the requirements of the HRN EN ISO 15614-2 standard, the phenomenon of strength drop in the area of the welded joint is described. The experimental part of the work was carried out by testing the hardness using the Vickers method, with the HV5 load on the mentioned aluminum alloys, and the width of the area of the heat-affected zone was quantified. Finally, the relative decrease in strength in the area of the welded joint was determined, and the application of the AC MIG process in the production of aluminum welded structures was proposed.
