Abstract
U ovom završnom radu obrađene su značajke čelika otpornih na trošenje specifikacije HARDOX 450 te je analizirana njihova primjena. Također su opisani problemi koji se mogu pojaviti kod zavarivanja, odabir dodatnog materijala, temperature predgrijavanja, unosi topline te parametri za MAG postupak zavarivanja. Analiziran je utjecaj unosa topline na mehanička svojstva zavarenog spoja. U eksperimentalnom dijelu osmišljen je plan ispitivanja za određivanje optimalnog unosa topline. Zavarivanje je provedeno MAG postupkom i to za sučeljeni spoj na više razina unosa topline. Računskom metodom utvrđena je kritična razina vremena hlađenja između 800 i 500 ⁰C obzirom na čvrstoću i omekšavanje u zoni utjecaja topline. Određena je optimalna razina unosa topline i dani su napuci o primjeni definirane tehnologije u realnoj proizvodnji.
