Abstract: |

TIG welding is very commonly used method in production engineering for joining metal parts. There are so many process parameters which affect the quality of weld joints. This process is widely used for welding of various metals and alloys like different grades of SS (stainless steel), Titanium, Aluminium, etc. Welding has been applied to various industries in particular, construction, automotive, aerospace and microelectronics etc. However there are many methods for welding the work pieces and one of the methods among these is vibratory welding. It has the advantages of less investment, more convenient operation, less pollution and shorter manufacturing period. In vibratory welding, work piece vibrates in the whole welding process and it mainly effects the welding solidification to improve the quality. Vibration facilitates the release of dissolved gases and the resulting weld beads greatly exhibit reduced porosity. Mechanical properties of the welds prepared under vibratory conditions are dependent on the structural changes of the welds. Many articles describe the benefits of vibration during welding on mechanical properties of weldments. Present work will emphasize on the effect of mechanical vibration on inner defect, and mechanical property of dissimilar and similar metal joints in TIG welding. As a result, this review will provide the improvement in mechanical properties and reduction in defects of weld joints by applying mechanical vibrations during the tungsten inert gas welding process of joining. The reduction in defect of welded joints can be measured with help non-destructive testing methods such as Penetrant Testing. |
