中文摘要：通过对B610CF-L2钢板焊接性分析和焊接工艺评定，确定了合理的焊接工艺参数。现场组焊严格按有关标准和技术要求进行，尤其球罐的焊接严格控制了焊接线能量，球罐各项指标均优于技术条件要求，产品试板力学性能良好。结果表明，-50 ℃B610CF-L2钢板各项性能均能满足2000 m3低温球罐建造的需要。
英文摘要：The reasonable welding parameters were determined by welding procedure qualification and analysis of the B610CF-L2 steel welding. The good mechanical properties of the product test panels are obtained in strict accordance with the relevant standards and technical requirements, in particular, the welding heat input was strictly controled. The results show that -50 ℃ B610CF-L2 steel can meet the construction technology of 2000 m3 spherical tank.
