| Abstract: | The welding continuous cooling transformation curve has been mensurated by thermal simulation technology and the microstructure transformation regulation of heat affected zone has been determined.Through maximum hardness test and Y-groove type cracking test,optimal preheat temperature and reheat embitterment sensitive temperature have been determined.The welding technology adaptability has been valued by coarse grain zone thermal simulation.The results indicated that the weldability of 13MnNiMoR steel plate was well and the results were helpful for determining welding technology. |
