This video describes flash butt welding of rails to obtain test welds.
The purpose of welding is to join rail ends together by the application of heat and thus eliminate the evil effects of rail joints.In flash butt welding, heat is generated by the electric resistance method. The ends of the two rails to be welded are firmly clamped into the jaws of a welding machine.One of the jaws is stationary, while the other one is moveable and as such the gap between the two rail ends can be adjusted.
