摘　　要：为满足国内对大线能量用钢的需求,首钢开发了用于大型石油储备罐建设的大线能量钢板SG610E。并对其进行了大线能量焊接性研究工作,结果表明,大线能量钢板SG610E经线能量100kJ/cm气电立焊后,焊接接头在-20℃下仍具有优良的低温韧性,钢板可用于建造大型石油储罐。For the high demand of the steel alloy for high heat input welding,SG610E is developed in Shougang group for using in the construction of large oil equipment with high heat input.Lot of high heat input weldability work has done for the SG610E oil tank steel alloy in this paper,and the results indicate that under the heat input of 100 kJ/cm,the -20℃ impact toughness of the SG610E weld joints is yet very high, and it is very suitable for the construction of large oil tanks.
