    Abstract :

    In this paper the study was done to investigate the effect of vibratory set up on the mechanical properties of 10 mm thick AISI 1018 Mild Steel welded butt joint. The enhancement of the welding mechanical properties and the quality of the fusion metal was considered recently by using vibration during welding. During the welding of metals along with mechanical vibrations, uniform and finer grain structures can be produced. This increases the toughness and hardness of the metals, because of solidification effects at the weld pool surface. As the weld pool solidifies, grains are not only limited in size, but dendrites growing perpendicular to the fusion line are restricted. While the process was going on, dendrites can be broken up before they grow to become large in size. Hence, the microstructure of the weld metal is improved during the solidification process.In this work, dynamic solidification technology was used by applying mechanical vibrations during the ‘Arc welding’ process. Analyses had been carried out for mild steel pieces having 10 mm of thick butt joints. The results obtained from the current study pointed out that the butt welded joint fabricated with vibratory condition are found to possess relatively high strength, without any considerable loss in its ductility. Following results were obtained during conduction of research work. Tensile strength 18.25 %, Elongation 39.34 %, Force 29.17 %, Reduction in area 50 % and Yield stress is 3.21 % was more with vibration as compared to without vibrations welding with SMAW
