A REVIEW PAPER ON EFFECT OF WELDING SPEED AND GROOVE ANGLE ON STRENGTH OF BUTT WELD JOINT USING TIG WELDING

W elding is most important operation in any industry. It is essential to optimize the various parameters of welding process so that we can achive the reliability, productivity and quality of the products. So industries are forcing the engineers to look at the welding process parameters such as electrodes, inert gas, current, voltage etc. The ojecti ve of any industry is production of high quality products at low cost and increase the production rate. TIG welding process is versatile and commonly used operation for joining of two materials with the application of heat and /or pressure or fillet mater ial to increase the production with less time and cost.The upgoing study is carried out to investigate the influence of welding speed, groove angle and bevel height on strength of mechanical properties such as tensile test, impact test. Also the current st udy aim to investigate the effect of welding speed on hardness of HAZ(Heat Affected Zone) and longitudinal and transvesr distortion of butt weld joint. Mechanical testings are carried out to find out the mechanical properties of butt weld joint.
