Abstract：
The effect of welding line zone, heat affected zone and matrix materials zone on the welding joint performance of hull high strength steel was studied. The technical means of improving the plastic, toughness and strength control of welded joints were discussed. The temperature field distribution and solidification process of welding metal microstructure were simulated by computer, and according to the simulation of the best conditions for the smelting of steel species verification experiments. The results show that this method can effectively improve the quality of welded joints. Welding and computer simulation of high strength steel hull is the future development direction.
