Modeling and Parametric Optimization using Factorial Design Approach of Submerged Arc Bead Geometry for Butt Joint

By Rati Saluja and K M Moeed


Automatic and robotic welding systems could used effectively, when optimal process parameters for achieving the desired quality and relative effects of input parameters on output parameters can be obtained. Response surface methodology (RSM) technique is applied to determine and characterize the cause and effect relationship between true mean responses and input control variables influencing the responses. This paper deals with the application of Factorial design approach for optimizing four submerged arc welding parameters viz. welding current, arc voltage, welding speed and electrode stick out by developing a mathematical model for sound quality bead width, bead penetration and weld reinforcement on butt joint
