Abstract

This study attempts to investigate the micro structure and wear behavior done on the surface of carbon steel. In doing so, specimens of carbon steel were filled through gas tungsten arc welding (GTAW) applying pulse and continuous currents by filler metal. The cross-section samples were examined by light microscopy and electron microscopy. The hardness test, the hardness of the samples was determined. Pin on disc wear test to evaluate the wear resistance of plain carbon steel specimens coated and welded something done. The wear surfaces were examined by scanning electron microscopy. Therefore, a sample with pulse configuration the lowest wear rate is the highest surface hardness. In order to optimize the welding conditions and the impact of each of the factors used to determine the degree of difficulty in pulsed mode, the Taguchi experimental design technique and the use of S / N ratio have been used. Finally, the overall results of the analysis revealed that the variable factors, peak flow and low flow, respectively, are considered the most influential factors on the response.
