A C-Mn-Si base chemistry with Ni addition and V-N microalloying had been designed for producing low yield strength high toughness steel plate via control rolling and normalizing process.The resulted steel plate had been conducted welding thermal simulation test.Welding test results show that with the increase of t8/5 time,ie,the increase of heat input,the hardness and impact value of HAZ decreases.Microstructure observation indicates that volume fraction and grain size of ferriteare the main reason for the deterioration of CGHAZ performance.Good CGHAZ performance can be achieved at 12.36～14.27 kJ/cm of heat input.
