Welding technology of aluminium armoured collectors

U ovom radu obrađena je proizvodnja i tehnologija zavarivanja oklopljenih aluminijskih sabirnica koje proizvodi tvrtka Končar Metalne konstrukcije d.d. U uvodnom dijelu rada obrađen je aluminij kao konstrukcijski materijal za izradu oklopljenih sabirnica, njegova svojstva i zavarljivost. Opisane su vrste oklopljenih sabirnica, njihova primjena i specifični spojevi. Obrađeni su MIG i TIG postupci zavarivanja aluminija. U eksperimentalnom dijelu rada obrađene su norme koje se koriste u zavarivanju oklopljenih sabirnica. Zavareni su ispitni uzorci i ispitani nerazornim i razornim metodama ispitivanja. Na temelju dobivenih rezultata doneseni su zaključci o tehnologiji zavarivanja i primjenjivosti aluminijskih sabirnica u realnim uvjetima. Eksperimentalni dio rada proveden je u tvrtki Končar Metalne konstrukcije d.d. i u laboratorijima Fakulteta strojarstva i brodogradnje Sveučilišta u Zagrebu.This thesis deals with manufacturing and welding technology of aluminium armoured collectors which are produced by Končar-Steel Structures Inc. The introductory part includes detailed literature overview of aluminium as base material for production of armoured collectors, its properties and weldability. Types, specific joints and applications of armoured collectors are described. Also welding of aluminium with MIG and TIG welding processes are described. Experimental part of thesis specifies welding standards which are used as reference in welding technology of armoured collectors. Test specimens were welded and inspected with non destructive and destructive test methods. Based on experimental results, conclusions about welding technology and application of aluminium armoured collectors in real terms were made. Experimental part of the thesis was conducted at Končar-Steel Structures Inc. company and in laboratories of the Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb
