    • Contrasting the mechanical and metallurgical properties of laser welded and gas tungsten arc welded S500MC steel
    Authors: Meiabadi, Saleh; Nematzadeh, Fardin; Kornokar, Kianoosh;  Advisor: -;  Co-Author: - (2023)

    S500MC steel is a grade of high-strength low-alloy steel (HSLA) which is widely used in the automotive industry and for agricultural machinery and equipment. Considering properties of this alloy, selection of the welding process and parameters becomes essential to ensure that HSLA assemblies meet specific service requirements. In this work, mechanical and metallurgical properties of S500MC steel produced by autogenous laser beam welding (LBW) and automatic gas tungsten arc welding (GTAW) were compared. Tensile testing, metallography, hardness testing, and fractographic analysis were performed on the welded specimens, revealing that the heat input by these welding processes caused sign...
