Welding is an efficient method for joining of metals. Welding has made significant impact on large number of industries due to its flexibility, low fabrication cost and high rate of production. And also out of available different types of welding Arc welding is widely used because of its high reliability, deep penetration, smooth finish and high productivity [1]. Welding is a method in which coalescence of metals is achieved by fusion in which there is extremely high localised temperature which products distortion and high level of residual stress. This tends to reduce the strength of structure which becomes more vulnerable to fracture and fatigue failure during operation [2]. Fatigue life analysis of various mechanical components is influenced by various factors but it becomes more complicated in case of welded structures because of additional variables such as residual stresses, distortion and various weld defects. Fatigue analysis of weld is done with the help of various international standards such IIW, Eurocode, etc. According to IIW and other standards fatigue of weld can be commonly assessed by three ways. These are Nominal stress, the Structural Hot Spot and the Effective Notch stress approach. And also their applicability varies with different applications.
