• Phase and group velocities of waves in a free rail are better understood. The operating deflection shapes measured to identify coupled modes. A synchronized multiple-acceleration wavelet is developed for dispersion analysis. Experimental methods study multimodal dispersive proposed. In this paper, we present solution method based on finite element (FE) modeling predict rail. As well as the mo...

The aim of this study concerns the effect multi-pass shielded metal arc welding (SMAW) on corrosion behavior CW6MC cast nickel alloy. Using optical and SEM techniques welded joint is analyzed. Vickers microhardness mapping potentiodynamic polarization in NaCl H2SO4 solutions are also evaluated. Both Laves phase NbC-type carbides identified base (BM) weld (WM) regions. main microstructural diffe...

Arc welding processes, such as shielded metal arc (SMAW), inert gas (MIG), and tungsten (TIG), play an important role in industrial applications. To improve the efficiency of exploitation traditional systems, new technologies have been used. Virtual reality technology is one them. The virtual (VR)-based system enables to increase frequency practice help learners obtain experience avoid errors t...

Advances in manufacturing emphasize on the development of sustainable and green processes. Welding is a popular process practiced worldwide. The paper presented here describes new covered electrode for shielded metal arc welding (SMAW) wherein nano-sized calcium titanate (CaTiO3) powder was used as an stabilizer, replacing conventional micro sized CaTiO3 flux. effect this flux modification mass...
