Characterization of orifice gas flow through a tubular, coated consumable welding electrode by CFD analysis
Employing tubular coated consumable welding electrodes by modifying the conventional shielded metal arc welding (SMAW) is a recently developed concept aimed to make the welding process towards more environmentally friendly by eliminating organic cellulose in the flux coating. The modified process na...

Employing tubular coated consumable welding electrodes by modifying the conventional shielded metal arc welding (SMAW) is a recently developed concept aimed to make the welding process towards more environmentally friendly by eliminating organic cellulose in the flux coating. The modified process named as Plasma Enhanced Shielded Metal Arc Welding (PESMAW) employs controlled orifice gas flow through the tubular electrode which is a key parameter for the process to achieve the objectives of its development. In this study, tubular electrode flow channel model was generated and simulated to investigate the fluid flow characteristic with multiple volume flow rates. Two orifice gases, Argon (Ar) and Carbon dioxide (CO2) were considered for the study and a commercial finite element tool for Computational fluid dynamics (CFD) was used. The velocity profile at each point on the entire length of the electrode at fully developed region was identified with in the fluid flow stream and the development from Laminar to Turbulent flow was also observed. The standard identification method of theoretically computing the Reynolds number (Re) was adopted and the simulated results were compared with the theoretically calculated results for validation. |
