摘　　要：论述了国内外贝氏体钢轨焊接研究现状。对国外,论述了日本、美国对贝氏体钢轨焊接缺陷及焊后热处理对组织性能影响的研究;对国内,论述了贝氏体钢轨的发展、焊接与焊后热处理工艺,焊接过热区出现白色微区、夹杂等缺陷的原因分析与解决措施。The research status on welding of the bainite steel rail in China and other countries was discussed. In foreign countries such as Japan and America, the influence study of welding defects and postweld heat treatment on the microstructure and properties of the bainite steel rail was discussed. In China, development and welding and post welding heat treatment process of bainite rail, and the cause analysis and solution of the white micro-area, inclusion and other defects in the welding overheated zone were expounded.
