Abstract

Ovaj rad u svom teoretskom dijelu opisuje oklopne celike velike tvrdoce i pojave koje se događaju tokom njihovog zavarivanja. Isto tako sadrži dio za bazicno razumijevanje terminalne balistike oklopa. U prakticnom dijelu postiže se eksperimentalnim putem povecana balisticka otpornost zavarenih spojeva oklopnih celika velike tvrdoce kombinacijom više razlicitih dodatnih materijala razlicitih tvrdoca. Eksperiment obuhvaca ostvarivanje zavarenog spoja, njegovo balisticko ispitivanje kao i ispitivanja tvrdoce i vlacne cvrstoce te makro-analizu. Primarni cilj je postojecim tehnologijama zavarivanja kontrolirati tvrdocu zavarenog spoja cime se osigurava balisticka otpornost dok je sekundarni cilj zadovoljiti potrebe cvrstoce spoja.

Abstract (english)

This thesis in its theoretical part describes high hardness armor steels and effects that happen during their welding. Also it contains part about most commong used welding processes as well as part about basic understanding of terminal balistics of armor. In practical part through experimentation enhanced ballistical endurance of welded joints of high hardness armor steels combining several different welding wires of different hardness is investigated. An experiment consists of joint welding, their ballistical testing as well as hardness and yield strenght testing. Primary goal is to control the hardness of welded joint by existing welding technologies to ensure ballistical endurance whilst secondary goal is to satisfy requirements for joint strenght.
