Abstract

This article presents a scientific and technical analysis of the composition and physical-mechanical properties of coated electrodes and their influence on the quality of welded joints. During the study, the structural characteristics of the electrode core and coating layer, the metallurgical and technological properties of electrodes, the mechanisms of weld formation, and their operational performance were investigated. In addition, the effects of mineral and alloying components contained in the electrode coating on arc stability, weld quality, and the physical-mechanical properties of the weld metal were evaluated. Based on the research results, scientific principles for electrode selection in welding processes and technological recommendations aimed at improving quality indicators were developed.
