Description:
The quality of a welded joint is strongly decided by the input parameters of the plasma arc welding process. The mathematical models used to predict the optimum tensile properties based on the input process parameters of the plasma arc welding. In this investigation, the response surface methodology is applied to optimize the tensile properties of the Plasma arc welding of AA8011-H24 aluminium alloys and Ti3Al2.5V Titanium alloys by proper selection of process parameters such as welding speed, welding current and gas flow rate. The three factors, five levels central composite design was applied to conduct the experiments. The impact of the process parameters on tensile properties of the plasma arc welding process was investigated by using the sensitivity analysis of the mathematical models. The welding speed was the more sensitive parameter on the tensile properties of the plasma arc welding compared to the other parameters followed by the welding current and gas flow rate.
