MOHSIN IQBAL QAZI, Rehman Akhtar

Abstract


In present study the effects of Shielded Metal Arc Welding (SMAW) parameters on analysis of tensile strength on SA 516 grade 70 was performed. SA 516 grade 70 is commercially used for manufacturing boilers. Analysis was performed at three levels of welding speed, root face and welding current were varied on to determine their effect on tensile strength at room temperature. The experiments were designed using Taguchi L9 orthogonal array, performed. Taguchi signal-to-noise ratio was applied for single objective optimization and to observe significant control parameters and optimal levels that improved tensile property. Analysis of variance showed that welding speed as most significant parameter with contribution of 69 % followed by welding current and root face, respectively.
