Abstract:
At this article presented the results of researches on studying of influence of basicity index BI of the electrode coating and the Melting Temperature Tm of the slag of electrode coatings consisting of a two-component CaO-SiO2 oxide system and ore-mineral raw materials of the Republic of Uzbekistan on the welding and technological properties of the welding electrodes. The relationship between these indicators was determined, the strength of linear correlation of which was estimated using the coefficient of determination R2. The influence of the BI value on such properties of the welding electrode as the breaking length of the arc, the formation of the deposited metal, and the formation of a visor or cover at the end of the electrode is established. Based on the research results, recommendations for the basicity index BI of the electrode coating were identified, which can be used in the development of electrode coating compositions for their effective impact on the welding and technological properties of welding electrodes.
