WebMar 11, 2024 · Weld slag inclusion is among the most significant drawbacks that negatively impact the welded joint’s reliability and quality. Most common incidences of slag inclusion can be traced to poor handling of flux, using low-quality flux, and not following the proper welding techniques. WebThe results obtained are summarized as follows : 1) By reducing CaO/SiO2 and CaO/Al2O3 ratio of top slag, MgO contents in Al2O3 based inclusions decreased. 2) The two film theory was employed to analyze the rate determining step of slag/metal reaction (reduction of MgO in top slag). By this model, it was found that the rate determining step of ...
