        Welding slag is a non-metallic byproduct of the welding process, playing a pivotal role in both protecting the weld pool and influencing the final weld’s quality. The article “The Role of Slag in Welding Process” from WeldWiki delves into the multifaceted functions of welding slag, its composition, classification, and characteristics, as well as its impact on welding outcomes.

        Key Points:

        • Mechanical Protection: Slag shields the molten weld from the atmosphere, preventing contamination and oxidation.
        • Metallurgical Treatment: It interacts with the molten metal to remove impurities and can introduce beneficial alloying elements.
        • Welding Process Performance: Proper slag composition ensures stable arc burning, reduces spatter, and enhances bead appearance.
        • Composition Variations: Slag contains various compounds like SiO2, TiO2, Al2O3, and others, influencing its properties and suitability for different welding applications.
        • Classification: Slag is categorized based on its base components into salt-based, salt-oxide-based, and oxide-based, each with distinct applications.
        • Alkalinity: The slag’s alkalinity affects its structure and, consequently, its impact on the welding process.
        • Melting Points and Densities: These factors of slag’s primary compounds are crucial for the welding process, affecting slag formation and removal.
