Keywords:
Flux cored arc welding, analysis of variance, taguchi method, grey based genetic algorithmAbstract
This paper presents the application of Taguchi method coupled with grey based GA approach for multiple output optimization of flux cored arc welding (FCAW) to obtain optimal weld bead geometry in mild steel plates IS 2062.This approach converts complex multiple objectives into a single grey reasoning grade which is the objective function for genetic algorithm (GA) approach. The welding parameters such as voltage, current, stick out and wire feed are optimized with multiple considerations such as bead width, penetration, reinforcement and dilution. Taguchi’s concepts of orthogonal array signal to noise (S/N) ratio has been used to optimize FCAW through a single comprehensive output measure (COM) which is the objective function. The significant contributions of parameters are estimated using analysis of variance (ANOVA) test. Confirmation test is conducted and reported. It is found that welding current is the most significant factor affecting bead geometry. Results indicate feasibility of grey based GA analysis in continuous improvement of welding industry.References
