A Study of Mechanical Properties of Vibration Assisted Arc Welding Joint

Abstract

Welding is one of the major aspects of manufacturing as well as mechanical engineering. The strength of the metal joint depends on the type of welding used.  Quality of metal joining strength can be improved with a few changes in the regular welding process. A few factors that improve metal jointing strength during the arc welding process had been studied in this paper. Research in welding process shows that Vibration can improve mechanical properties of the joining section. However, welding joint quality varies with different ranges of parameters in different conditions. To analyze those ranges of parameters in some selected conditions, a study has been performed in this paper. Some input parameters like vibration amplitude, vibration frequency, welding speed and electrode angle are selected to analyze the variation in the welded joint. For analyzing the results, output parameters –bending strength and dilution rate are calculated. It has been found that if all input parameters are kept in a selected range then output parameters –bending strength, the percentage of dilution increases than the regular case. Finally, it can be shown that Bending strength and percentage of dilution of a metal joint assisted with vibration shows the better result than without vibration.
