ABSTRACT
Welding defects influence the desired properties of welded joints giving Fabrication experts a common problem of not being able to produce weld structures with optimal strength and quality. In this present work, the fuzzy logic system was employed to predict welding fatigue. 30 sets of welding experiments was conducted and fatigue data was collected which was converted from crisp variable into fuzzy sets The result obtained showed that the fuzyy logic tool is a highly effective tool for predicting fatigue present in TIG mild steel weld having a coefficient of determination value of 99%
