1. Selection of arc welding parameters of micro alloyed HSLA steel

Author

M. Dunđer, Ž. Ivandić, and I. Samardžić

Subjects
HSLA, Welding parameters, Cooling time _t8/5, Hardness, Impact energy, Mining engineering. Metallurgy, TN1-997
Abstract

In order to ensure performance reliability of a welded product, its quality has to be ensured by proper setting of welding parameters and welding cycle. A quality weld – a weld with no manufacturing, structural or geometric flaws, i.e. with necessary mechanical properties - is achieved only by correct parameter definition and adherence. The knowledge of various effects and relations between welding parameters and their repetition enable an optimal choice of welding parameters.

2. Impact energy analysis of HSLA specimens after simulated welding thermal cycle

Author

Samarždić, I., Aračić, S., and Duđner, M.

Subjects
HSLA, Welding thermal cycle, Impact energy, Cooling time ∆t8/5, Mining engineering. Metallurgy, TN1-997
Abstract

This paper presents impact energy results of specimens made from high strength fine grained steel TStE 420 after thermal cycle simulation. These results are obtained by examining Charpy specimens. Metallographic analysis is performed, hardness is measured and total impact energy is divided into ductile and brittle components.

Abstract

In order to ensure performance reliability of a welded product, its quality has to be ensured by proper setting of welding parameters and welding cycle. A quality weld – a weld with no manufacturing, structural or geometric flaws, i.e. with necessary mechanical properties - is achieved only by correct parameter definition and adherence. The knowledge of various effects and relations between welding parameters and their repetition enable an optimal choice of welding parameters., Za pouzdan rad zavarenog proizvoda potrebno je kvalitetu osigurati pravilnim određivanjem parametara i slijeda zavarivanja. Pravilnim propisivanjem i provođenjem parametara zavarivanja osigurava se kvalitetan zavar, zavar bez proizvodnih, strukturnih i geometrijskih grešaka, odnosno s potrebnim mehaničkim svojstvima. Poznavanje utjecaja i odnosa između parametara zavarivanja te njihova ponovljivost omogućuje izbor i propisivanje optimalnih parametara zavarivanja.
