Standard Features on Integrated Precision Bore Cladder
The precision column lift is achieved through a servo motor driven lead screw drive along machined rails. Precision lifting of the boom provides the system with the necessary vertical motion for spiral or step index cladding. A flexible cable carrier is included to organize and protect the life of the cables during motion.
The precision boom drive features a servo motor driven rack and pinion drive along machined rails for horizontal motion of the bore torch. The precision drive is controlled and driven by an AVC (Arc Voltage Control) module for constant arc standoff during cladding. A flexible cable carrier is included to organize and protect the life of the cables during motion.
A 4-roll wire drive assembly that is driven by a servo motor with encoder feedback provides precision wire delivery. Wire feed speed, start delay, and wire retract are each programmable with the XM Controller. The wire feeder offers high-precision wire delivery with an accuracy of +/- 1% of the programmed speed. The wire feeder also includes a manual hotwire nozzle positioner that is mounted to the torch.
The AMET bore torch is water-cooled and equipped with the necessary components for hotwire feeding. The torch is rated at 200 Amps at 100 percent duty-cycle.
The included turn table is capable of continuous rotation for cladding the entire part without stopping. The rotating motion is controllable and programmable through the XM Controller.
AMET’s precision hotwire power supply preheats the wire prior to entering the weld puddle, which increases wire deposition over a cold wire GTAW system. The preheating of the welding wire also provides a cleaning effect, which improves the quality of the weld puddle. The current and voltage are adjustable up to 200 Amps and 20 Volts respectively.
A 350 Amp DC GTAW welding power supply is integrated into the system for programmable control of the weld parameters. The power supply is capable of cladding with a wide range of filler metals including hard metals like Inconel.
A 500 Amp water circulator is integrated into the system to prevent the weld torch from overheating.
A single point power distribution cabinet is included that provides fuse-protected power to the entire system from a single primary power circuit (provided by client).
Optional Features on Integrated Precision Bore Cladder
Additional Manipulator Travel
An additional 24 in (610 mm) of precision travel can be added to either the vertical or horizontal travel axes of the manipulator. These additional capacities increase the work envelope so larger parts can be clad than with the standard version.
AMET’s turntables are available with larger weight capacities.
5,525 lb (2500 kg)
11,000 lb (5000 kg)
22,100 lb (10000 kg)
Larger Bore Torch
AMET’s compact bore torch is included with this system. AMET’s standard bore torch is available for medium sized bores. With this larger torch, the minimum bore diameter is increased to 3.5 in (89 mm). The standard bore torch length is about 48 in (1219 mm) as opposed to the standard 36 in (914 mm) of the compact torch.
Intersecting Bore Cladding Capability
Intersecting bore location and size can be programmed through the XM® or XPro Controller. During cladding, the arc will automatically be extinguished when the torch reaches the edge of the intersecting bore and then reignite once it reaches the other side. This will be repeated until the system has clad around the entire intersecting bore and then continuous cladding will resume. Bores must intersect the main part at an angle perpendicular to the center.
Offline Programming Software
Weld programs can be created, modified, or stored on a PC. These programs can be moved back and forth between the controller and the PC using a USB storage device or through an Ethernet connection. This software can increase productivity by allowing programs to be created/edited while the weld controller is executing another weld program.
Arc Viewing Camera
Arc Viewing Cameras can be added to a GTAW/PAW system giving the operator a view of the weld arc from a remote location. This keeps the operator in a safe location and reduces operator stress and fatigue. Additionally, the image that is shown on the monitor is magnified and shows greater detail than what could be observed without the camera. Multiple cameras may be integrated for projects where a view of the lead and trail side of the weld zone is required. Please see the Arc Viewing Camera page for additional information.
Grippers and Chucks
A variety of optional part holding devices may be added to standard faceplates. These include grippers, three jaw scroll chucks, three jaw pneumatic chucks as well as other part holding solutions.
Complex Intersecting Bore Cladding
Includes all of the features from the Intersecting Bore Cladding option with the addition of automatically cladding bores at off-center and off-angle intersections.
End Uses For Integrated Precision Bore Cladder
Valves used in the oil and gas industry often require corrosive resistant coatings on sections of the inner diameter or along the entire length. Bore cladders are used to apply the corrosive resistant metals to the ID of valves.
Parts with intersecting bores can be welded with AMET's welding systems. This is facilitated by our use of intelligent software matched with premium hardware.
Blowout preventers require corrosion-resistant overlays of the bores and components to ensure they can withstand harsh oil and gas environments. Our systems and controls provide an excellent solution for BOPs whether your company is the primary manufacturer or performs repairs.
Ball valves require corrosion-resistant overlay for use in the oil and gas industry. Our systems are programmable to automatically clad around the opening of the ball for a completely automated solution.
