S.Veera jeyendra prakash, V. Manivel Muralidaran

Abstract


The input parameters of welding play a very important role in determining the quality of a weld joint. The weld joint quality can be defined in terms of weld-bead geometry, mechanical properties, and distortion. Generally, all type of welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters, excellent mechanical properties with minimum distortion. Response surface methodology is used to develop a mathematical relationship between the welding process input parameters and the output variables of the weld joint in order to determine the welding input parameters that lead to the desired weld quality.

Keywords : Gas metal arc welding, Response surface methodology, Regression equation
