建筑结构用钢2Cr13和1Cr18Ni9焊接接头的组织与力学性能分析

The organization and mechanical property analysis to building structural steel 2Cr13 and 1Cr18Ni9 in welded joints

分析对比了建筑用钢2Cr13马氏体钢和1Cr18Ni9奥氏体钢在不同焊接方法下的焊接接头组织,得到了不同焊接接头显微硬度的拉伸强度。比较结果表明异体钢焊接接头的组织和力学性能比同种材料有所降低,采用适当的焊接方法可以提高焊接接头的组织和力学性能,这一研究有助于实际生产中选择适当的焊接材料和焊接方法。

This paper analyzes and compares the construction steel Martensitic steel 2Cr13 and Austenitic steel 1Cr18Ni9.The different tensile strengths of micro-hardness in welded joints by different welding methods have been obtained.The results show that the organization and mechanical properties of different steel welded joints are lower than that of the same material,and the organization and mechanical properties of welded joints can be improved by adopting the appropriate welding method.This study will help to choose the appropriate welding materials and welding methods in the process of production.
