Low Temperature Welding Test and Numerical Simulation of Metallurgical Phase Transformation of Q460GJC Thick Plate

This paper conducts low temperature welding tests on Q460gJC thick plate (60 mm), and based on the basic theory of phase transformation structure evolution, a three-dimensional microstructure evolution analysis method for large welded joints is established, and the analysis of the evolution process of multi-layer and multi-pass weld structure under the low temperature environment of thick plates is completed. The comparison and analysis of test and numerical simulation results are in good agreement, which proves that the welding phase transformation model realizes the digitalization of metallurgical phase transformation in steel structure welding, and optimizes welding process parameters. it is of great significance to improve the quality of welding products and lay a foundation for predicting the performance of welded joints from the micro level.
