In this article the influence of welding parameters such as electrical current, feed rate and stick out on crack growth energy was investigated. Therefore, prepared specimens were welded in various conditions. Using the Minitab software, 18 states of 36 possible states were chosen and applied. Then a crack was crated on the weld metal and the force-displacement diagram was plotted. Comparison of results shows that in high electricity current, the extra heat flux is the dominant factor, which causes coarse grains of microstructures. On the other hand, in low electricity current, lack of fusion and penetration reduce the crack propagation energy. Furthermore, the neural network could predict the amount of energy with high accuracy.
