Abstract

It was investigated for statistical analysis on impact toughness of welded joints between B610CF and 16MnR steel using shielded metal arc welding (SMAW) and mixed gas arc welding (MGAW) method. Low temperature(-20 C) impact toughness experiments and normal temperature(20 C) impact toughness experiments after 5% strain age were carried out on weld metal (WM) and heat affected zone (HAZ) of the welded joints. F testing, t and t' testing statistical methods were used to analyze the difference of welded joint impact toughness between the two welding methods. The statistical analysis shows that the disperstiveness of impact toughness (-20 C) in WM using SMAW is significantly smaller than the one using MGAW, but the mean value has no significant difference. And there are no significantly statistical difference for the disperstiveness and mean value of -20 C impact toughness in HAZ, and normal temperature impact toughness after 5% strain age in WM and HAZ between the two welding methods.
