Product Description
DR600 Flash-Butt Welding Containe
The system is designed for tunnel operation and plain line. Theunit is designed to run with high
flash point fluids and all cables and hoses are fittedwith fire proof shields. The system is complete with a diesel engine generator set and
integral cooling system. Voltage control is by means of direct control.
Hydraulic power is derived from a hydraulic pump driven from a 30kW electrical motor.
The electrically driven pump provides power for both the welder and the crane. A 21 kW chiller,
complete with circulating pumps, is provided to ensure the welding head operates within the
correct temperature levels. This cooler is electrically driven from the generator secondary circuit.
Range of application:
Flash butt welding of short or long rails into machine.
Rail lengths, minimal continuous tracks by means of a welding 1.5 m
Rail profiles: Standard rail profiles:36 - 75 kg/m
Vignole rail Rail sections up to
Material identification:10.000 mm2
R220, R260, R260Mn, R350HT
For welding of different rail types, only the initial settings are needed to be made and
once they have been made, the machine can weld the same rail type without other
subsequent settings.
Production capacity (thermal capacity):
For profile UIC 60, burr removal included,
DR600 Welding Head
The main features of the DR600 welding head are the following:
The welding head DR600 can weld both vignole and grooved rail (it needs specific
electrodes and shearing knife for required rail type) and can be easily converted.
The machine DR600 is designed for flash-butt welding by continuous flashing of rails
with cross-section area from 6.400 mm2 up to 10.000 mm2 with flash removing
immediately after welding under field conditions being a part of movable rail-welding
plants.

Shearing Knife
Full profile shearing shall be achieved by passing the shear tooling across the weld immediately
after the weld is made. The cutting edge is build-up by hard facingelectrode for high temperature
working conditions 850 °C.
Welding Electrodes
Contact with the rail web is by special material electrodes. The electrodes aremade by forged high
quality alloy with good electrical conductibility and hardness 220 HB.
These are specially designed with spring loaded location points to ensure accurate alignment
of the rail ends for welding. Adjustments are available within the system to ensure that alignment
is possible according to EN14587-2:2009.
Control and Power Cabinet
The system controls all aspects of the welding cycle including the final shear. Specific welding
schedules are available for most rail sections and can be developed for any special requests.
Weld time is typically 2.5 to 3 minutes with approximately 25 – 38 mm of rail consumption.
Welding voltages are varied according to the rail size and according to the welding program.
These voltages are provided by a powerful thyro control and are in the range of:
- Stage I and II 400-440 V
- Stage III 300-340 V
WPC 2.0 (Welding Process Controller)
The control system provides for:
− control of actuators and mechanisms of welding machine both in manual andautomatic operation modes;
− control of process cycle in accordance with welding machine cycle pattern
being programmed in dependence of moving frame travel with continuous flashing;
− tolerance testing and welding cycle parameter registration with issue of certificate for welded
buttin dicating its usability or defects.
The Welding Process Controller(WPC) gives information about the following
parameters of the welding process:
the effective size of voltage in the welding transformer (V)
the effective value of current in the welding transformer (kA)
the forging force - the force of pressing together the rails to be weld (kN)
the displacement of the welding jaws (mm)
the time elapsed during the welding process (s)
the temperature of the environment during the welding process (°C)
the GPS position of the welding machine during the welding process
Hydraulic Power Unit
This pump is a gear type pump, 9 l/minute flow and is driven by 3 kW electrical motor which can
be connected to any external portable gen-set.
Hydraulic power unit furnishes: at 400V, 50HZ
100 l/minute at 130bar for welding head circuit
25 l/minute at 160 bar for crane circuit
9 l/minute at 160 bar emergency circuit for welding head and crane
25 l/minute at 10 bar for cooling/filtration circuit
Cooling Unit
A cooling unit is provided to ensure the welding head operating temperatures aremaintained within
pre-set limits.
This is the most economic configuration, which is obtained by calibrating the finned heat
exchanger banks to allow proper operation of the refrigerator at externalair temperatures not
exceeding 55°C.
