| Abstract: | In this paper, the COD experiments of 09MnNiDR and SA-537 steels which were used in LPG tank is conducted, and the low temperature fracture resistance of welded joint is determined. Some important influential factors on fracture behavior are also discussed, such as the welding materials, the welding processes, the welded joint area (weld, heat-affected zone, fusion line and base metal) and the experiment temperature. The yesults provide a scientific basis for selection of the materials and the welding processes and the fracture behavior analysis of the LPG structures. |
