Fatigue life estimation of $CO_2$ gas arc welded carbon steel tubes

In this study, the fatigue lives of two kinds of specimens made by co/sab 2/ gas were assessed. The materials for two kinds of specimens were taken out of the virgin carbon steel tubes and used carbon steel tubes, respectively. As a result, it was found that the fatigue lives of two groups of specimens were in the same order of magnitude.
