| Abstract: | Micro-shear test was applied to study the properties of welded joints of WDL610 steel.Gradient curves for strength character and plastic property were drawn,that made the properties and its variation law of each narrow zone in welded joints showed directly.Especially,the softened zone's performance indexes and width affect the load-supporting capability of the quenched and tempered steel's welded joints seriously. |

| Keywords: | micro-shear test gradient curves of property softened zone WDL610 |
