In this study, geometric shape and crack in welded interface of the air cooled heat exchanger Fin-Tube was analysed. The object of study is to give insight for understanding the behavior of Stress Intensity Factor for fin length, flash thickness, flash length, symmetric and asymmetric cracks of fin producing in manufactural processed. Stress Intensity Factor was analysed by BEM. Kelvin's solution was used as a fundamental solution in BEM analysis and displacement extrapolation method was used to determine Stress Intensity Factor.
