limited track maintenance time. In the light of those, we developed a rail grinding machine for welds to improve grinding work efficiency. Using the developed machine, rough grinding of the rail top surface was completed in four minutes and manual finishing in 22 minutes. As a result, the whole welding process could be completed in 26 minutes, demonstrating that the machine couldDevelopment of a Rail Grinding Machine for Welds,Development of a Rail Grinding Machine for Welds. Future Shinkansen rail renewal scheduled on the basis of passing tonnage will require much rail welding work. Rail welding work includes the actual rail welding along with grinding, and it currently requires considerable manpower because both are done manually.

As one of the largest contract service welders in North America, we have consistently designed and manufactured reliable railWelding a Rail Joint methods used on railways,08/04/2016· 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. It is not necessary to specially prepare the rail ends, though these can be preheated with an oxy-acetylene torch, if necessary. The rail endsHow to grind, blend and finish a weld seam | Norton,19/03/2019· Grinding wheels should be the choice for carbon steel. They will remove the weld seam quickly and since the appearance of scratches are not such an issue compared to stainless steel, are ideal for this operation. Typically, in the spectrum of 5 to 35 degrees to the horizontal (depending on the grinding wheel used) should be the target.
