Parametric Optimization of Weld Reinforcements using Response Surface Methodology Optimization Process
SADA, SO
Abstract
This study analyzes the effect of the process parameters such current, voltage, gas-flow rate and weld
speed on a 10mm thick mild steel plate for minimum reinforcement height using the tungsten arc welding process. With
the use of design expert, response surface methodology was applied in constructing a design matrix, analyzing the data
and obtaining a mathematical model. The minimised weld reinforcement of 0.016mm was observed at a weld current
setting of (200amp), voltage (18volt), gas flow rate (22L/min) and speed (4.5mm/sec) with a desirability value of 0.983.
The analysis of variance (ANOVA) test performed to ascertain the adequacy of the model, showed that the welding
current and gas flow rate had the most significant effect on the weld reinforcement.
