Investigation on Mechanical Properties of SMA Welded Carbon Steel Joints by Varying Joint Design and Groove Angles

This paper discussed about the experimental investigation of mechanical properties of SMAW welded carbon steel plates IS 2062 E350 having two different joints single V and double V groove and also varying the groove angles as 40°, 50°, 60°, and 70° by keeping constant current and voltage as constant. From the observed results, the double V groove joint with groove angle of 50° have maximum tensile strength than the other joints. The maximum toughness was achieved in the double V groove joint with 60° groove angle than 40°, 50° and 70°. In hardness double V groove joint with 50° groove angle is prior to all other groove angles By comparing the results, double V groove joint with groove angle of 50° provides the satisfactory results from this investigation.
