摘要：In this competitive world, the customers perceive the most reliable high quality with low cost product.Gas metal arc welding famously abbreviated MIG is one of the most important metals joining process in manufacturingindustries. The selection of improper MIG welding process parameter increases the power consumption, materialconsumption, man power and cost of the product decreasing the weld quality. This project work was part of theprogram for the development of SA 387 steels has to be increase mechanical properties and minimization ofmetallurgical defects to increasing weldment quality. The quality of weld in MIG mainly influenced by independentvariables such as welding current, speed of electrode and electrode stick out. The planned experiments were conductedin the MIG welding machine.. Image J software were used to find out the depth of penetration depending upon thetemperature variation. Experimentally found the input parameter value AMPS 160 VOLT-22 ROOT GAP 1.5 was thebest value and it did not create any major changes and failures in the testing process and it was comparatively moderatetoughness value than other value and it also induces high tensile strength. According to the Taguchi design theoptimized parameter value for 10 mm plate of SA387 steel is AMPS 180 VOLT-22ROOT GAP- 1.5.
