Abstract

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. The objective of the present work is to evaluate the effect of SAW parameters for hardness of weld bead. The response function of the trial conditions would be match the constituents of transfer elements with the base metal. In the beginning of D.O.E phase, pilot experiments will be performed for preliminary study. The various parameters, their ranges and levels will be selected based on results of the pilot study. The results are expected to show that the response variables (output parameters) will be strongly influenced by the control factors (input parameters). So, the results which are obtained after experimentation shall be analyzed and modeled for their application in manufacturing industry. The purposed work is to evaluate the effect of SAW parameters for hardness of weld bead. In this work the experimentation is done to analyze that which factor is most contributing towards the various element transfers in weld bead. The results and analysis shows that the current is most contributing factors for most of the element transfer. After that with the help of graph plot from Minitab software, the optimized combinations were obtained for different elements.

Keywords: SMAW, GMAW, DOE etc.
