Abstract (Croatian)

Tema završnog rada je „Reparaturno zavarivanje sivog lijeva“. Prije uvoda u samu problematiku zavarivanja sivog lijeva, vrlo je važno dobro poznavanje samog materijala, odnosno njegovu mikrostrukturu, kemijski sastav i svojstva. U radu su detaljno opisani postupci zavarivanja na toplo i hladno popraćeni dodatnim materijalom, tehnikom rada i pripremom žlijeba. U radu je navedena i priprema sivog lijeva tehnologijom lemljenja. Također su opisani primjeri reparaturnog zavarivanja primjenjivih u održavanju postrojenja i strojeva. U eksperimentalnom dijelu završnog rada prikazan je tehnološki postupak i parametri zavarivanja radnog komada od sivog lijeva. Detaljno je prikazan dodatni materijal, uređaji, te alati koji se koriste. Na kraju je provedeno ispitivanje s kojim se dokazala kvaliteta repariranog dijela. Cijeli postupak je popraćen uz obilje izvornih slika iz laboratorija.

Abstract

The theme of the dissertation is "Repair welding of cast iron." Prior to introduction into the issue of welding cast iron, it is very important to a good knowledge of the material, and the microstructure, chemical composition and properties. The paper describes welding on hot and cold accompanied by additional material, the technique and the preparation of the groove. The paper listed the preparation of cast iron soldering technology. Also described are examples repair welding applicable in the maintenance of plant and machine. The experimental part of the dissertation presents the technological process and the welding parameters of the work pieces made of cast iron. There are detailed additional materials, equipment, and tools used. In the end there was conducted test which had to prove the quality of the repaired parts. The whole process is accompanied with plenty of original pictures from the lab.
