Optimization of response parameters for polarity in submerged arc welding

Abstract

Purpose – Optimization of response parameter is essential in any process .The purpose of this paper is to focus at achieving the optimized parameter for submerged arc welding to furnish the quality welds at direct current electrode positive (DCEP) polarity and direct current electrode negative (DCEN) polarity. Design/methodology/approach – This paper achieves the parameter after extensive trial runs and finally parameters are optimized to acquire the cost effective and quality welds in submerged arc welding using the response surface methodology. Findings – Apart from effect of parameters on weld bead geometry has been identified but optimized parameters has also been achieved for submerged arc welding process for DCEP and DCEN polarities. Practical implications – As this study is related to practical work it may be useful for any relevant application. Social implications – The process parameters used in this experimental work will be basis for job work/industry for submerged arc welding. Originality/value – This paper identifies the effect of polarity in submerged arc welding.
