Abstract

U ovom završnom radu obrađena je analiza svojstva zavarenog spoja niskolegiranog čelika 10CrMo9-10 MAG postupkom. Rad se sastoji od teorijskog i eksperimentalnog dijela.

U teorijskom dijelu završnog rada opisan je MAG postupak zavarivanja i načini na koji se može izvoditi. Uz to obrađeni su i čelici za rad pri povišenim i visokim temperaturama te promjene do kojih dolazi prilikom rada na povišenim i visokim temperaturama. Poseban naglasak stavljen je na niskolegirani 10CrMo9-10 čelik koji je detaljno opisan. Nakon teorijskog dijela rada uslijedio je eksperimentalni dio.

U eksperimentalnom dijelu rada na spoju zavarenom MAG postupkom zavarivanja provedena su ispitivanja mehaničkih svojstava i analizirane su geometrijske karakteristike zavarenog spoja. Ispitivanja obavljena u sklopu eksperimentalnog rada su: ispitivanje tvrdoće, ispitivanje mikrostrukture i makrostrukture.

Abstract (english)

In this undergraduate thesis analysis of properties of welded joint of low-alloy 10CrMo9-10
steel with MAG method have been processed. The thesis consists of a theoretical and an
experimental part.
The theoretical part of the final paper describes the MAG welding process and the ways in
which it can be performed. In addition the high temperature resistant steels and changes that
occur when working at elevated and high temperatures have been discussed. Special emphasis
is placed on low-alloy 10CrMo9-10 steel which is described in detail. The theoretical part of
the paper was followed by the experimental one.
In the experimental part of the work on a weld welded by the MAG welding process, tests of
mechanical properties were performed and the geometric characteristics of the welded joint
were analysed. The tests performed as part of the experimental work are: hardness testing and
analysis of microstructure and macrostructure.
