Optimization of FCAW Process Parameters for SA 387

In this competitive world the customers perceive the most reliable high quality with low cost product. Flux Core arc welding famously abbreviated FCAW is one of the most important metals joining process in manufacturing industries. The selection of improper FCAW process parameter increases the power consumption, material consumption, man power, cost of the product and decreasing the weld quality. This project work is part of program for the development of SA 387 steels has to be increase mechanical properties and minimization of metallurgical defects to increasing weldment. The quality of weld in FCAW mainly influenced by independent variables such as welding current, speed of electrode and electrode stick out. The planned experiments are conducted in the FCAW welding machine. Image J software has to be used to find out the depth of penetration depending upon the temperature variation. According to experimental investigation found out the input parameter value AMPS – 140, VOLT-20 & BEVEL ANGLE-65 º is the best value and it does not create any major changes and failures in the testing process and it was comparatively moderate toughness value than other value and it also induces high tensile strength. According to the Taguchi design the optimized parameter value 10 mm plate of SA387 steel were AMPS – 140,VOLT-20, BEVEL ANGLE-70º and mainly influenced with Amps 55%.
