Quality assessment of single-pass corner steel welded joints
Zdravko Praunseis, Bojan Stergar, Iztok Brinovar, 2021, original scientific article

Abstract: The aim of this paper is to analyse the quality assessment of single-pass corner steel welded joints. The testing revealed the most burdened welded joints, which were cut out of the workpiece and prepared for metallographic macroscopic and microscopic analysis. Thus, for all examinations of single-pass corner steel welded joints, the standard test procedures were used to determine the weldability and quality assessment of base materials and welded joints. Additionally, the effects of various welded defects of single-pass weld material on the bearing strength of corner welded joints will be analysed.

In-service damage of railway steel axles
O. Jasnìî, Tomaž Vuherer, Ju. I. Pindus, Andriy Sorochak, Ivan Samardžić, 2011, short scientific article

Abstract: The influence of temperature and specimens undercut place on impact toughness of railway axle material in service is investigated. The obtained results show inversely proportional dependence of impact toughness on undercut radius of specimens. The decrease of test temperature from +20 to –40 ºC decreases significantly the impact toughness and portion of ductile fracture.
