TENSILE STRENGTH OF WELDED MILD STEEL SPECIMEN ON UNIVERSAL TESTING MACHINE

The aim of my paper is to find the various properties of mild steel specimen which is welded by mainly three welding . Quality and productivity play important role in today’s manufacturing market. Now a day’ s due to very stiff and cut throat competitive market condition in manufacturing industries. The main objective of industries reveals with producing better quality product at minimum cost and increase productivity. Welding is the most vital and common oper ation use for joining of two similar and dissimilar parts.In the present research paper an attempt is made to understand various welding techniques and to find the best welding technique for steel. Special focuses have been put on TIG , MIG , ARC welding. On hardness testing machine and UTM various characteristics such as ultimate tensile load, ultimate tensile stress, breaking point, % elongation etc. were analyzed
