摘　　要：我国在现代有轨电车用槽型钢轨焊接过程中创新地采用了移动闪光焊接,并发展出了多种成套的新装备。但槽型钢轨焊后出现了一定数量的弯曲接头,需要在焊后处理时进行矫直。本文重点介绍了WJZ-1型有轨电车用槽形钢轨焊接接头焊后矫直作业系统的功能特点、工作原理、性能指标和主要结构,并介绍了其应用情况。Mobile flash butt welding technology was used in groove rail welding process of modern tramway in China and multiple sets of new equipment were developed.There were a certain number of bending joints after groove rail welding,which should be straightened during post-weld heat treatment.Functional characteristics,working principle,performance index and main structure for post-weld straightening operation system of groove rail welding joints used in WJZ-1 tramway and its application were introduced in this paper.
