CONSTRUCTION
a) Welding Head: The welding head
consists of the wire feed mechanism incorporating a high torque DC
geared motor, wire straightening and feed rollers, welding tip,
vertical adjustment mechanism, and a flux hopper (in case of
Submerged Arc version)
The welding head can be adjusted transversely and
also vertically to bring the weldsing tip in correct position. It
can swivel upto 45 degree for fillet seams in flat
position.
b) Tractor Carriage: Fabricated
from sheet steel with four wheels, either suitably insulated steel
wheels for travelling on rails or rubber tyred wheels for travelling
on the job.
The trolley is deiven by a high torque DC geared
motor with the help of chain and sprocket arrangement, giving power
to the four wheels, thereby avoiding any slipping of the wheels, The
trolley supports the cross beam fitted with welding head on one side
and control box, on the opposite side, which can either be fixed on
the top of the trolley or at the bottom of the trolley with the help
of suitable suspension arrangement.
A suitable clutch arrangement disengages the greared
motor for manual pushing.
Controls: Thyristor control for
traction and wire feed speed is offered. The equipment consists
of:
Control Panel:
It is mounted on the other end of the corss beam opposite to the
welding head can be fixed at any convenient angle for easy reading
or parameters and incorporates:
- Meters for reading welding current, voltage and
carriage speed.
- Potentiometer for wire feed and carriage speed
adjustment.
- Push buttons for upward and downward inching of
the electrode wire.
- Switches for start and stop of welding.
- Forward, off and reverse movement of the
carriage.
- The panel for Thyristor Control equipment
includes PCB's for wire feed and carriage speed controls
(thyristor control system) D.C. supply voltage for motors, control
fuses and switching socket.
