摘要
CRH6城际车转向架构架多用异质钢焊接接头连接,其热影响区的组织性能,通过焊接接头力学性能分析及测试,确定合适的焊接工艺参数和工艺措施,保证焊接接头的质量和力学性能,为制造CRH6转向架构架提供试验依据。
To CRH6 intercity EMUs,welded joints of dissimilar steel are universal used on bogie frame. By analysising microstructure of heat affected zone and testing of mechanical properties of welded joints, the appropriate welding process parameters and technological measures is obtained to ensure the quality and mechanical properties of welded joints, thus providing the experiment basis of bogie frame of CRH6 intercity EMUs.
