Welding and Its Necessity
Joining of two rails ends by the application of heat is called “WELDING”
A fish plated joint has been a necessary evil in the track. To over come the various problem posed by the fish plated joint such as battering, hogging, rail end
failure, noise pollution, distortion of track geometry etc and to reduce the maintenance cost welding is best solution.
Types of Welding:-
1. Gas Pressure Welding (Oxy-Acetylene Welding)
2. Electric Arc Welding
3. Thermit Welding
4. Flash Butt Welding
