TYPICAL SEQUENCE OF OPERATION
1. Old Coil End is stopped in the shear area of the RCM.
2. Exit Side Guide closes, centering the Old Coil End.
3. Exit Weld Clamp Closes.
4. New Coil End is stopped in the shear area of the RCM.
5. Entry Side Guide closes, centering the New Coil End.
6. Entry Weld Clamp closes to "Soft Touch".
7. Camber Compensation of the New Coil End.
8. Entry Weld Clamp closes.
9. Roller Shear cuts both Coil Ends simultaneously.
10. Entry Weld Clamp positively positions (gaps) New Coil
End at the Old Coil End. At the same time, the Backup Bar
is positioned.
11. Weld Torch(es) join the coil ends together.
12. RCM resets and the process line can restart.
MAIN OPTIONS
A. Full Automation - The machine operates automatically,
and all weld parameters are determined automatically
from strip data obtained from PLC.
B. Hole Punch - Used to identify, track, and locate the
weld as it passes through the process line.
C. 8" or 12" Vertical Clamp Opening - Allows for easy threading
of wavy edged, non flattened coil ends.
D. Dual Torch Welding - Reduces the overall machine cycle
and weld time. This is very important on continuous process
lines and pipe mills.
E. Strip Edge Notcher - Used to notch the weld start and
stop (high stress) areas off the joined coil ends. Also
used to remove the "wings" when welding a new wide coil
end to a narrow old coil end. These are also needed for
Side Trimmer insertion and removal.
F. Weld Bead Milling Unit - Used to remove the excess weld
off the top and or bottom of the weld joint. This is usually
done when the weld will be kept in the coil for further
processing, such as coil buildup.
Guild International has a complete line of Coil End Welders
for almost any application.
