Investigation of welding parameters on impact strength of low frequency vibration assisted butt-welded joints using Taguchi methodology
A Taguchi method was applied to investigate the optimal parameters in low frequency vibration assisted welded joints. Shielded metal arc welding (SMAW) method was used with low frequency vibratory technique to impart vibration with a 100 Hz frequency to the workpiece during welding. This work aims to set optimal parameters for impact strength of weld joints. The effect of various welding factors like welding current, vibration time and vibration frequency have been characterized and optimized by Taguchi methodology and response surface technique to achieve on optimum condition. L27 orthogonal array was used for designing the experiments. The findings demonstrated that the most important determining factor for impact strength is the frequency of vibration due to which considerable increase in impact strength of welded specimen has been observed. The optimum welding parameters for maximum impact strength were obtained at current of 120 A, frequency 100 Hz and vibration time 60 s. Microstructure investigation using SEM analysis on mild steel specimen welded using vibration assistance revealed a fine structure.
