Abstract

Welded joints were made by a bulk welding process using S355J2+N Z15 non-alloy steel plate, commonly used in the construction of bridge structures, to investigate the extent to which deviations from the thermal loading values specified in MSZ EN ISO 15614- 1 alter the properties
of the welded joints. Welded joints were subjected to destructive and non-destructive tests. A significant variation in the heat input had the greatest effect on the hardness and impact values of the welded joint. The test results and experimental experience may contribute to the development of correct welding techniques for the tested types and le-field thicknesses of steels and to the reduction of welding defects during fabrication.

Keywords:
