Element of Pure Weld Metal(PWM) is important factor that understand to analyze Flux's conduct in Submerged Arc Welding(SAW). For elements of PWM were got, pile-up welding over 10 floor have used in the past. But, it take a long time to analyze elements of PWM in this method. Elements of PWM is needed to seize more easily. In this research, no using pile-up welding over 10 floor, bead welding is used to graps an element of PWM using mathematical formula which get to be derivation. The value calculated mathmatically was compared with the actual value of pile-up welding.
