Abstract

Welded joints of Q1100 ultra high strength steel were made via gas shielded arc welding with welding heat inputs of 10 kJ/cm and 15 kJ/cm respectively. The microstructure, mechanical properties and local corrosion behavior of welded joints were studied. The results show that the microstructure of weld zone for the two welded joints is mainly acicular ferrite and a small amount of granular bainite. The microstructure is lath bainite for the coarse grain zone, and lath bainite and granular bainite for the fine grain zone of the weld joints. The microstructure of the critical phase transition zone is a mixture of polygonal ferrite, Mayo islets and carbide. The charge transfer resistance of various portions of the two welded joints could be ranked as the following order: base metal > heat affected zone > weld zone. The base metal had the best corrosion resistance, followed by the heat affected zone, and the weld zone had the worst corrosion resistance. During the corrosion process, the weld zone was first corroded as an anode. After a certain time of corrosion, the corrosion position changed, and the anode corrosion area was transferred into the base metal, while the weld zone was protected as a cathode. The welded joint with heat input of 10 kJ/cm has better low temperature toughness and corrosion resistance. The impact energies are 46.5 J and 30.2 J for the weld zone and heat affected zone respectively at -40℃.
