Influence of Flexural Strength on Welded Joints under the Effect of Electrode Vibratory Welding Process

Vibration techniques play a prominent role in welding process for enhancing the mechanical properties of material from past two decades. In this current work, electrode vibratory setup is connected to the electrode for transferring vibrations mechanically through electrode to weld-pool during arc welding process. The fabricated novel vibratory setup generates the required amount of frequency in-terms DC motor voltage. Through these vibrations an enhanced flexural strength of weldments at HAZ is studied. The improved mechanical properties are due to refinement of the weld-pool before solidification and the dendrites are breaks down into smaller size. The microstructure analysis reveals the small nuclei formation which is the main reason for improved flexural strength.
