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 30 0 , 40 0 , 50 0 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.

Generally the V-groove geometry with included angle up to 60 0 is in use. After studying the Indian Welding Journal published by Indian Welding Society it is observed that strength of joint is depends upon depth of penetration of filler material and Heat Affected Zone. So this paper concentrate on effect of welding speed on depth of penetration of filler, distortion and HAZ.
