Abstract
U ovom diplomskom radu obrađena je analiza svojstva zavarenih spojeva konstrukcijskog čelika primjenom različitih dodatnih materijala kao i različitih smjesa zaštitnih plinova. Rad se sastoji od teorijskog i eksperimentalnog dijela. U teorijskom dijelu diplomskog rada opisan je MAG postupak zavarivanja i načini na koji se može izvoditi. Uz MAG postupak zavarivanja obrađeni su i opći konstrukcijski čelici te je navedeno gdje se primjenjuju. Naglasak u teorijskom dijelu rada stavljen je na dodatni materijal za MAG postupak zavarivanja, tj. na metalnim prahom punjene žice. Opisana su svojstva metalnim prahom punjenih žica i uspoređene su s konvencionalnim punim i praškom punjenim žicama. Opisane i navedene su dvokomponentne i trokomponentne mješavine zaštitnih plinova pri MAG postupku zavarivanja. Nakon teorijskog dijela rada uslijedio je eksperimentalni dio. U eksperimentalnom dijelu MAG postupkom zavarivanja zavareno je sedam uzoraka. Uzorci su zavarivani konvencionalnom punom žicom i metalnim praškom punjenom žicom uz primjenu dvokomponentne i trokomponentne mješavine zaštitnog plina. Nakon toga analizirani su makroizbrusci.
Abstract (english)
The analysis of properties of welded joints of structural steel using different additional materials as well as different mixtures of shielding gases has been processed in this graduate thesis. The thesis consists of the theoretical and the experimental part. The MAG procedure of welding and the manners of performing it have been described in the theoretical part of this graduate thesis. Along with the MAG procedure of welding, the general structural steels and their use have also been processed. The focus of the theoretical part was put on additional materials used for MAG procedure of welding. Metal cored welding wire took most of that focus. The properties of the metal cored welding wire have been described and they have been compared with the conventional full wires and flux cored wires. Two and three-component shielding gas mixtures used in the MAG welding procedure have been described and listed. The experimental part followed after the theoretical part. Seven samples have been welded using the MAG welding procedure in the experimental part. The samples have been welded by the conventional full wire and the metal cored welding wire with the application of two and three-component shielding gas mixture. After the process, microstructure of samples was analyzed.
