Tóm tắt bài báo: This paper introduces the results of a study examining the microstructure of the material at the weld interface and the adjacent heat-affected zone depending on certain technological parameters of electroslag pressure welding, for the purpose of comparing with experimental research results on the tensile strength of butt welds of reinforcing steel bars according to an orthogonal plan of 3 levels and 3 factors (N27). The obtained results contribute to providing recommendations on the range of suitable welding parameters under the conditions of the existing equipment line in the laboratory, ensuring working performance according to the requirements of load-bearing structures in construction works in Vietnam.
