Effect of vibratory welding process on hardness of dissimilar welded joints

This paper presents the effect of vibratory dissimilar TIG (Tungsten Inert Gas) welding process on hardness of welded joins with respect to change of vibratory parameters. In this study, new vibratory setup with two metal engravers is used to give mechanical vibrations to the specimens to be welded. | Effect of vibratory welding process on hardness of dissimilar welded joints Engineering Solid Mechanics 2017 133-138 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Effect of vibratory welding process on hardness of dissimilar welded joints J.

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
