Overview:
Indian Railways, the world’s fourth largest national railway network in terms of total track length over a 68,103-kilometer route, transports over 20 million passengers and 2 million tones of freight per day. On its rail network of 63,327 km, Indian Railways runs more than 200,000 wagons and 50,000 carriages pulled by more than 8,000 engines; it also runs 6,909 stations and has over 1,400,000 employees, which makes it the third biggest employer in the world.
SILASERS designed, developed, and manufactured a fully automated Fiber Laser Cutting and Welding System to conquer the challenges and complexity of manufacturing elongated railway bogies. As we are known for Innovation with Excellence, which reflects in our Solutions, for making the intricate process easier and faster for the growing Industrial scope with our high precision, accuracy, and automation-enabled features.
Railway coach side walls and roofs
SIL has commissioned an innovative SCW 2.5×25 automatic Fiber Laser Cutting – Welding Machine to produce side walls and roofs for its passenger wagons. This is a sheet cut and weld system designed and customized by SIL as per the client’s specifications. SCW stands for “Sheet Cut and Weld,” and 2.5 indicates the maximum weld length; 25 m indicates the maximum welded sheet length that the system can handle. The machine produces semi-finished parts that are used for manufacturing railway coach sidewalls and roofs, including windows and doors.
The Fiber Laser Cutting – Welding Machine 2.5×25 is made up of a Cutting and Welding base table with gantry and dual Z-axis for cutting and welding, a machine enclosure, a control panel, a chiller, a fume extractor, a raw sheet loading table, and a sheet rolling table. The sheets are rolled out automatically from the trimming-welding station and cutting station with the help of two rollers at both stations, which will sandwich the sheet and move the sheets towards the sheet rolling table. This operation is done by servo motors, thanks to which we can get the exact position of the sheet without any error.
