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.
• Camera based real time part to part coordinate measurement, helping accurate cutting for long length sheets.
• Laser including 2 Fiber Cable & 2-way beam switch(Time Sharing)
• Advanced welding head with seam tracker
• Wobble Welding Head (Optional)

The handheld laser welding machine combines quality of laser with flexibility of traditional welding to user’s advantage. The handheld laser welding machine is very easy to operate, which offers perfect welding seam without usage of any consumables at a fairly fast welding speed. The handheld laser welding machine can replace the traditional argon welding and electric welding.

Usage of Li-Ion battery is increasing exponentially in various sectors such as mobiles, automobile, defense, aerospace, etc.

SIL has recently developed battery welding machine for Li-Ion batteries. These batteries are made of prismatic containers having materials like Al, Al alloy, SS or OFHC Copper. These machines are used for welding can-caps, terminals, fill tubes, tabs, etc. The components can have thicknesses from 0.5 mm upto 3 mm.

Type of Lasers that can be used are either CW or QCW fiber Laser. The machine produces positioning accuracy of better than 10 µm and positioning speed > 18 m/min.

Other important features are welding process monitoring thru video camera, power ramping & pulse shaping, welding head with wobble motion, seam tracking with path compensation to name a few.

Q-switched fiber lasers are capable of providing pulse energies in the mJ range, but for materials processing applications requiring multiple Joules of pulse energy at multi-kilowatt peak powers IPG has developed the unique Quasi-CW Fiber Lasers. These fiber lasers occupy the space between kW class CW fiber lasers and Q-switched pulsed lasers. They are very similar to kW class fiber lasers with one notable difference: their peak power during ON time is up to tenfold higher than their average power in pure CW mode of operation. Thus, these lasers can provide tens of joules of energy over a long pulse, from 50 microseconds to 50 milliseconds.

Feaatures

• Laser power from 75 W to 2.3 kW.
• Peak power will be ten times more than actual power.
• Fully automated and IOT 4.0 enabled.
