摘要

軌道工程是軌道運輸中不可或缺的一環，對採用鋼輪鋼軌之臺北捷運重運量系統，鋼軌
更是一重要元件，為了提高列車行駛之舒適性及降低行車噪音，採用連續長焊鋼軌(CWR)作

為行車軌道已是不可避免之趨勢，而連續長焊鋼軌則是兼具有電阻火花焊接(FBW)、鋁熱焊
接(TW)及鋼軌絕緣接頭(IRJ)將廠製鋼軌一根根續接而成。臺北捷運自淡水線以來均採用連
續長焊鋼軌進行舖設，本文將針對臺北捷運軌道工程連續長焊鋼軌施工過程中，包括電阻火
花焊接、鋁熱焊接及鋼軌絕緣接頭等各項續接作業予以說明。

Abstract

Trackwork is an essential part of rail transportation. Especially for the Taipei MRT with steel
wheels and steel rails, the rails are a vital element. To enhance passenger comfort levels and
reduce running noise, the application of continuous welded rail (CWR) for the MRT running tracks
has become a necessary and foreseeable trend. CWR tracks are made from individual plant-made

steel rails that have been welded together using flash-butt welding (FBW), thermit-welding (TW),
and insulated rail joint (IRJ).
CWR has been used in Taipei MRT projects since the Danshui line was constructed. This paper
aims to describe the work processes of FBW, TW, and IRJ during the construction process of

CWR tracks.

Keywords: continuous welded rail, flash-butt welding, thermit-welding, insulated rail joint
