Indian railways which is the fourth largest railway network in the world by size, with 121, 407 kilometres of total track over a 67, 368-kilometre route and over 18million passengers and 2 million tons of freight traffic 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.

Railway coach side walls and roofs

SIL recently commissioned an innovative SCW 2.5X25 automatic laser cutting and welding system to produce side walls and roofs for its passenger wagons. This is a sheet cut and weld system designed and customised by SIL as per client’s specifications. SCW stands for “Sheet Cut and Weld”, 2.5 indicates the maximum weld length, 25m indicates the maximum welded sheet length that the system can be handle. The machine produces semi-finished parts which is used for manufacturing railway coach sidewalls and roofs including windows and doors of the coaches.

SCW 2.5X25 machine consist of Cutting and Welding base table with gantry and dual Z-axis of cutting and welding, Machine Enclosure, Control panel, Chiller, Fume Extractor, Raw Sheet Loading Table and finally Sheet rolling table. The sheets are rolled out automatically from trimming-welding station and cutting station with the help of two rollers at both station which will sandwich the sheet and move the sheets towards sheet rolling table. This operation is done be servo motors due which we can get the exact position of the sheet without any error.

Features:

• Laser welding station 2.5 x 22 m.
• Laser Welding Head Includes Wobbler, Seam Tracker and Monitoring System
• 3 Kw Fiber Laser with Dual Beam Switch Facility.
• Laser Cutting Station 2.5 x 4 Mtr.
• CNC Laser Weld-Cut System up to 26 meters length.

• Laser including 2 Fiber Cable & 2-way beam switch(Time Sharing)
• Advanced welding head with seam tracker
• Wobble Welding Head (Optional)

New Integrated laser system with pro features of 6X piercing speed with precise beam quality possessing high Laser power up to 20kW ensuring maximum reliability and productivity based on the type of material to be processed having benefit of minimal maintenance. We have wide range of Fiber Laser cutting machines integrated with EtherCat, Beckhoff, FANUC controllers & finest quality laser beam source of SIL OEM, IPG, FANUC of high laser power having variety in different working areas.

SIL machines have other features of vision cameras for monitoring the cutting process, pallet exchange, operator console with sheet clamping mechanism which secures sheet while cutting process. The special CNC advance controllers option prevents collision with anti detection and high speed Z Axis retraction on no sheet underneath or nozzle touch. QR code scanning system & compatible nesting software from Sigmanest, Lantek and Metallix also fall under advance features which we supply.

We provide some additional features such as Auto Nozzle Exchanger, Auto Nozzle Cleaner, Nozzle Beam Centring, Slat Conveyor (Optional).
