Introduction To overcome the disadvantages in normal welding process vibratory assisted welding has been introduced for improving mechanical properties of welded joints. In vibratory welding a force is applied periodically to the specimens during welding process. Due to this periodic force weld pool is stirred to refine the grain structure in order to enhance the weld joint properties. Lu et al. 2007 investigated to improve the quality of full welded valve by the application of vibratory weld conditioning VWC and the effect of VWC on the welded joint properties was studied. In their study cylinders
