| Abstract: | The weldability of 800 MPa high strength steel has been studied with 20 mm and 42 mm thickness plates by the maximum hardness test of heat-affected zone,Y slit cracking test and the test of weld energy input etc. The result shows that the high quality welded joint can be got by using appropriate preheat temperature and weld energy input.The weld energy input is suggested to be used in project as follows:20 mm thick, E<30 kJ/cm; 42 mm thick, E<45 kJ/cm. |
