Research the Microstructure of electroslag pressure weld joints used for reinforced steel in construction engineering

Abstract

The paper presents the research on microstructure analysis at the heat affected
zone and at the weld interface regions of electroslag pressure weld joints in
dependence of some welding technological parameters with reference to the
tensile strength results obtained in accordance with the three-factor 3-element
(N27) orthogonal planning. The results were served for determining the
suitable control domain of welding mode to ensure the required performance
of load bearing construction structures in Vietnam.
