Research on Weldability of Weldox700E High Strength Steel

Abstract

Abstract: The welding performance of the Sweden Vivitar Weldox700E high strength steel was analyzed. The microstructure and physical properties of the materials were systematically tested, and the microstructure of the heat affected zone and the problem of decline in toughness were analyzed. The results show that Weldox700E steel has good weldability, and there is a linear correlation between the organizational structure and the impact toughness, which provides a theoretical guidance for enterprises to determine the relation among organizational structure and physical properties in the welding process evaluation.

Key words: , high strength steel； weldability； organizational structure； impact toughness

摘要： 对瑞典威达Weldox700E高强度钢的焊接性能进行研究，测试了焊接区域显微组织结构和物理性能，分析了热影响区显微组织与韧性下降的关联问题。结果表明，Weldox700E高强度钢焊接性能良好，其组织结构与冲击韧性之间存在一定的线性关系。研究结果为企业在焊接工艺评定中确定中高强度钢组织结构和物理性能之间的关系提供了一定的理论参考。
