本文以A6061-T6材料進行摩擦攪拌銲接（FSW）之實驗，量取距離中央銲道不同位置之溫度。由量取之溫度進行回歸曲線分析以預測溫度分佈曲線，並推算中央銲道溫度。本文以最小均方根法求得之回歸曲線以二次曲線較接近實驗值。

Friction Stir Welding(FSW) experiments are conducted using 6061-T6 aluminum as specimens. The temperatures at different distances from the center of the joint are measured. Curve fitting analyses are used to predict the temperature distribution and calculate the central temperature of the joint, proceeding by measuring temperature. A second order curve is found to better fit the experiment values by the least square method.
