Steps For Welding Railroad Tracks | Railroad Thermite Welding

Aug 14, 2020 · Thermite welding for railroad track As we all know, railroad tracks are produced with certain lengths, such as 12.5m, 25m, and the lengthen ones from 50m to 100m. No matter how long the railroad rail is, they need to be joined end to end to make a continuous railroad. This can be realized by rail joints (joint bars) or welding methods.

Rail Welding Processes - Gantry Rail - Homepage - Gantry Rail

Puddle arc welding. Enclosed Arc (puddle arc) welding is widely used throughout the world for welding crane rails. Gantrail employ skilled technicians who can do this work or can train other operatives. In this method the two rail ends to be joined are cut square, placed about 20 mm apart, preheated and then welded using special manual metal arc electrodes.

Arc welding -

Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick (" electrode ") and the base material to melt ...

What are the different types of rail welding?

In the daily work of railway connection, there are four ways of rail welding, they are flash butt rail welding, gas pressure welding rail, thermite rail welding and electric arc welding railroad. When flash butt rail welding method is used to weld a rail, the first step is to place the two rail heads opposite each other.

Flash-butt Welding - rail system

The welding process is in principle a regulated electric short circuit with the two rail ends functioning as D.C. poles. The high current produces an arc between the rail ends, the two rail cross-sections are heated to melting temperature due to the high input of current.
