4.6.3.6 Station Ready: The operator will use this to let the system control/robot know that the fixture is loaded and the area is clear and ready to execute the welding program.

4.6.3.7 Enable Clamps: Turns on Power to the Clamps without actuating them. If this is off, the clamps cannot be actuated.

4.6.3.8 Clamps Open/Closed: Allows the operator to actuate the clamps to open or closed.

4.6.4 TOUCH SENSE: This is a control feature allowing the operator to choose to have the robot determine the location of the parts to be welded and automatically adjust to properly weld the selected joint. This shall be capable of locating the part in (quantity 3) dimensions. This feature shall be capable of being turned on/off as determined appropriate by the RIA-JMTC operator/programmer.

4.6.5 SEAM TRACKING: This is a control feature allowing the robot to automatically adjust vertical and lateral trajectory to compensate for part warping or misplacement based upon feedback monitoring of variations in the welding current and use of a robotic weaving search pattern. The system shall store the new path data to allow for increased speed when performing multi-pass welds (e.g. root pass memorization and multi pass offset features from Fanuc or equivalent). The feature shall include a “fill” function to maintain a constant fill for groove weld joints with a varying volume. This feature shall be capable of being turned on/off as determined appropriate by the RIA-JMTC operator/programmer.

4.6.6 COORDINATED MOTION: The system shall be able to operate with all robot and auxiliary axes having full coordinated simultaneous motion. Therefore the programmer shall be able to have any or all axes in motion at the same time.

4.6.7 ANTI-COLLISION PROTECTION: The controls shall include a feature to automatically avoid collisions. This feature will include prevention of collisions with a second robot if/when added in the future.

4.6.8 SERVO MOTORS: All servo motors and drives must be the same manufacture as the robot motors.

4.6.9 CONTROL TYPE: The system control may be a PLC (Programmable Logic Controller), a Robot Controller (e.g. Fanuc “i” type controller, etc.), or a combination of the two. The system may NOT include any type of PC (Personal Computer).

4.7 Accessories

4.7.1 TORCHES: The system shall include a water cooled torch for each weld power supply including a quick change mounting system. Each torch shall include a straight nozzle and either a 30° or a 22° nozzle. The torches shall have a minimum capacity of 400-amps or sufficient to accept the maximum capacity of the weld power supply (whichever is higher).

4.7.2 TORCH STRAIGHTENING STATION: The system shall include a straightening clamp/system that will correct bent torches after crashes.

4.7.3 TORCH CALIBRATION SYSTEM: The system shall include feature allowing the system to automatically determine the Tool Center Point. It shall automatically adjust for variance. It shall also automatically adjust the torch angle as necessary to compensate for variations in the tool center point. It shall be capable of operating with the selected weld power supplies. It compensates for bent torch barrels and worn contact tips. This will increase up-time of the system and reduce the amount of touch-up necessary.

4.7.4 TORCH CLEANING STATION: The system shall include a station for cleaning the torch. This shall be a program controlled feature through the robot controller. The program will periodically request torch cleaning. The robot will then move the weld torch to a designated location where the device will clamp the nozzle, then ream the weld slag from the torch/nozzle and contact tip and apply a spray of anti-spatter compound. This will reduce the amount of slag attaching to the torch and improve the life expectancy of the equipment and reduce maintenance time. The height of the reamer function shall be adjustable.

4.7.5 WIRE CUTTING STATION: The system shall include a cutting device for the weld wire. This shall be a station where the robot will move the torch and extend the weld wire. The cutting device will then cut the wire to allow the robot control to have an exact location for the end of the wire and remove the ball end of the wire. This is critical to the accuracy of the touch sense feature.

4.7.6 WIRE BRAKE: The system shall include a braking device to maintain the location of the weld wire. This device shall be located at the end of the robot arm (end of the 6th axis). The purpose of this device is to maintain the location of the snipped end of the weld wire. The robot uses this information as part of the touch sense feature. This is critical to the accuracy of the touch sense feature.

4.7.7 COOLING: Water cooling shall be provided by an appropriately sized Bernard water cooler (e.g. Coolmate-4). It shall be the responsibility of the vendor to determine the appropriate size equipment necessary to support up to (quantity 2) welding robots operating simultaneously.

This will include a water flow switch to ensure that water is being provided to the torch when needed.

4.8 Welder

WELD POWER SUPPLIES: The system shall be supplied with (quantity 2) weld power supplies. The weld power supplies shall be a Miller Auto-Axcess 450s. This will be used for MIG welding of mild steel components.

4.9 Wire Delivery System

4.9.1 WIRE DELIVERY/SUPPORT: The wire delivery system (except for the torch) shall not be supported or mounted to the robot. It shall be independently supported using a mechanical support and appropriately sized tool balancers.

4.9.2 BULK WIRE SUPPLY: While the track and carriage must be designed to carry a 1000-lb Spool with Dereeler, the initial system shall be supplied with (quantity 2) 500-lb drums (one on the carriage at a time, not both together). The vendor shall supply (quantity 1) 500-lb drum of 0.035-in diameter ER70S copper coated wire and (quantity 1) 500-lb drum of 0.045-in diameter ER70S copper coated wire.

4.10 Fencing

4.10.1 FENCING: The system shall be guarded using modular fencing panels meeting the ANSI/RIA safety standards. The front of the system (operator load/unload position) shall be utilize light curtains for physical protection and a Fromelt Roll Shield (or equivalent) to provide a vision barrier. The vision barrier may be manually or automatically extended or retracted, but must be included in the system safety circuit to prevent welding without the vision barrier in place. The panels shall be in standard length increments to allow mix/match construction of the perimeter fencing. This will accommodate potential future expansions or modifications to the base system. The fencing shall be tall enough to prevent direct line of sight from personnel outside the system to an active weld torch during the welding process. There shall be at least two gates with switches giving access to the area behind the work station. As a minimum, each gate shall include a viewing window (protected with weld rated vision protection).

4.10.2 CABLE TRAYS: The system shall include floor cable trays to contain all wires and hoses. The tray will include a cover and shall be built to withstand the weight of an operator/programmer walking on top without creating a hazardous working/walking surface.

4.11 Fixture: The vendor shall design, build, provide and program one fixture for Part #12564030 (Revision X5, or current Revision). The fixture provided shall be very similar to the fixture provided to RIA under Contract W9098S-11-P-0590 (very minor alterations, if any). The current part drawing is available from the Contracting Officer. The fixture shall include hydraulic clamping and sensors to determine that the clamps are in the correct position prior to executing the welding program. Rock Island Arsenal will be responsible for additional costs incurred by unforeseen, but controllable manmade issues. Examples would include, but are not limited to, significant changes in the size of the part or increases in complexity caused by addition of more components in the weldment. While these are not anticipated, they may occur and cannot be determined until the final component design is completed. The contractor will be responsible for all costs associated with correcting foreseeable conditions, including but not limited to torch access to weld joints, clamp sequencing to allow continuous weld seams, proper material selection to prevent weld spatter build-up, hydraulic line locations, protection of sensor lines, etc.

4.11.1 Fixture Support: In addition to providing the fixture, the contractor shall provide fixture support as outlined below:

4.11.1.1 Fixture Design Support: The vendor shall provide up to 40-hrs of engineering support to assist RIA-JMTC to design a fixture for welding. See attached part concept drawing. The vendor shall provide an engineer on-site at RIA-JMTC for 24-hours (3 consecutive work days) to assist in development of the fixture concept. RIA-JMTC will then develop detailed plans for the fixture. The vendor will provide the remaining 16-hrs of support to review the detailed plans and make suggestions for improvements (this time may be on-site or by telephone and internet).

4.11.1.2 Application Engineering: The vendor shall provide 120-hours of on-site application engineering time to develop and prove-out a program to weld the part (same part as fixture design support). This will be in increments of at least 40-hours each (maximum of three trips).

4.12 Future Capabilities

While it is not possible for all of the future capabilities to exist on the same system at the same time, any of these capabilities may be required for future projects. Therefore the base system must include the ability to add any of the following features with minimal modification:

4.12.1 Added Track Sections: The system must include the ability to add modular track sections to extend the length of the base system up to at least 72-ft. The connection cables, wires, and cable carriers would need to be replaced, but the existing track, carriage(s), and drives must be utilized (not replaced but added to).

4.12.2 L-Seat or Skyhook Positioner: The system shall include the ability to add a positioner that would mount only to the headstock and not be supported by the tailstock. This would be an “L” shaped positioner with a rotating fixture mounting at the bottom of the “L” (90° to the headstock mounting). This type of fixture would allow for additional access to welded frames. The positioner would utilize one of the auxiliary axis drives required as part of the base system and would therefore act as an additional robot axis.

4.12.3 Drop Center Positioner: The system shall include the ability to add a positioner that would mount to the headstock and be supported by the tailstock with a rotating fixture mounting in the center (90° to the headstock mounting). This type of fixture would allow for additional access to welded frames. The positioner would utilize one of the auxiliary axis drives required as part of the base system and would therefore act as an additional robot axis.

4.12.4 Boom Mount for Robot: The system shall include the ability to add a boom mount to the carriage of the track. This would then mount the robot upside-down and swing the robot over the work station. Modifications to the system fencing and guarding would be necessary to add this feature. The centerline of the robot (when boom mounted) would need to be at least 6-ft from the centerline of the track.

4.12.5 Y-Axis: The system shall be designed to allow for the addition of a Y-Axis positioner.

This positioner would mount to the carriage and replace the initial robot riser. It would be a servo controlled axis allowing the robot to move at horizontally at 90° to the floor track travel. It would utilize one of the auxiliary axis drives required as part of the base system and would therefore act as an additional robot axis.

4.12.6 Z-Axis: The system shall be designed to allow for the addition of a Z-Axis positioner.

This positioner would mount to the carriage and replace the initial robot riser. It would be a servo controlled axis allowing the robot to move at vertically at 90° to the floor track travel. It would utilize one of the auxiliary axis drives required as part of the base system and would therefore act as an additional robot axis.
