Abstract

The quality of weld joint is influenced by process parameters during the welding process. In order to achieve high quality welds, input process parameters should be controlled. In this investigation four input process parameters such as arc rotational speed, ratio of wire feed rate to travel speed, wire feed rate and eccentricity are considered. The experiments were conducted on square butt joint plate of 5083 H111 aluminium alloy using full factorial design of experiments. Output parameters like bead penetration, bead height, bead width are measured. The fuzzy models for bead penetration, bead height and bead width are developed using fuzzy logic. This fuzzy model has been used for prediction of output parameters. Accuracy analysis of weld bead geometry is also performed. It is observed that % of error is less than 10% in most of the cases for bead height and width and less than 20% for bead penetration.
