Abstract –The selection of improper FCAW process parameter may led to increases the power consumption, material consumption, man power, cost of the product and decrease the weld quality. This study was the part of program for the development of EN24 medium carbon  steels to increase mechanical properties and minimization of metallurgical defects to increasing good weldment. The quality of weld in FCAW mainly influenced by independent variables such as welding current, speed of the electrode, torch angle and bevel angle. The planned experiment were conducted in MIG welding machine. For the entire experiments, the welding current were chosen are 160A,170A,180A and the arc voltage is 20V, 22V,24V and the bevel angle is 55°,65°,70°. From the study, the good weldment obtained in the input parameter value was 180AMPS,24VOLT and 70° BEVEL ANGLE was the best value as maximum hardness , good impact and high depth of penetration.

Key Words: Hardness , Depth of Penetration, Welding current, Bevel angle, MIG welding
