At present, the welding performance of Q890 steel used in production is poor, mainly manifested in the low welding heat input, less than 20kJ/cm, which cannot meet the requirements of robot welding. In this experiment, thermal simulation test was used to study the microstructure and properties of heat-affected zone (HAZ) of Q890 steel after composition optimization under different ...
