The paper presents the results of testing the strength of butt joints welded with the GMAW
method. The base material of the joints was high-strength ferritic steel. The research
program included experimental and computational part. In experimental studies, precise
hardness distribution measurements were carried out to determine the extent of zones in
joints. On the basis of the hardness of the material, its strength characteristics were defined
in the relevant sections of the welded joint analyzed. Defining material properties and …
