INFLUENCE OF WELDING SPEED AND GROOVE ANGLE ON STRENGTH OF V-GROOVE BUTT WELD JOINT USING TIG WELDING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 4
Abstract
Welding is the metal joining process in which two or more metal having same material or different can be joined by heating to a plastic state .It is mostly used for joining metals in process industry, in fabrication, maintenance, repair of parts and structures. The metal plates and pipes used in process industry and they have welding strength as their important parameter. In this paper study of welding speed and geometry to find out tensile and impact strength in case of butt weld joint will be done. For V-groove geometry different models of plate with various included angles from 300 , 400 , 500 will be made from structural steel (A633 Grade E). Currently different welding speeds are used in precision welding applications such as nuclear reactor pressure vessels, boilers etc. where welding accuracy as well as quality with strength is an important parameter. So in this project experimentation will be done on different welding speed such as 0.3 cm/sec, 0.6 cm/sec and 0.9cm/sec to prepare a V-groove butt weld joint. Generally the Vgroove geometry with included angle up to 600 is in use. After studying the Indian Welding Journal published by Indian Welding Society it is observed that distortion and residual stresses increase with increase in groove angle . Joints strength also increases with groove angle increase of the welded material which affects the economy of welding. The industries facing problems related to strength, the V-groove geometry can make use of the satisfactory results obtained from this investigation.
