Standard Features on Retrofits
AMET Advanced Controls. The architecture used in AMET’s controls allow us to accommodate a wide range of power supplies, fixturing, safety, and automation equipment. The controls are designed and built in house to seamlessly integrate with existing equipment.
Precision and Manual Motion Axes. AMET produces and integrates motion axes and the necessary bracketry for vertical and horizontal weld head movement. The precision axes consist of servo motor driven components with encoder feedback for programmable motion and position. Manual axes are hand crank driven slides with manual brakes to prevent movement during welding operations.
Testing. AMET control components are produced in house, which allows us control over the quality and the ability to test each component as it is produced. This includes individual components such as control boards and complete assemblies like control modules and the XM Controller. Each component and assembly is rigorously tested, as is the whole system to ensure proper functionality, compatibility and longevity.
Fixturing. AMET performs retrofits on manipulator, seam welder, lathe, positioner, and cladding fixturing made by virtually any manufacturer. The fixturing can be new or used as long as it is functioning adequately at the beginning of the retrofit process.
Integration. The controls and motion components are integrated with the fixturing for performing hard automation welds. The advantage to an AMET retrofit is that we design the software and hardware of our controls to seamlessly integrate with each fixture. This holistic approach ensures compatibility with virtually any weld fixture.
Complete System. AMET provides complete systems with a warranty on all AMET produced components. Upon completion of testing and integration at the AMET facility in Idaho, we setup and install the retrofit system onsite at the client’s facility.
Optional Features on Retrofits
Intersecting Bore Cladding Capability
Intersecting bore location and size can be programmed through the XM 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 XM is executing a weld program.
A critical part of the allure of XM Controls is the ability to automate functions in the welding process. The system may be set up to enable laser tracking, start part rotation when the weld commences, and even load and unload a part. Up to10 pre-weld and 10 post-weld operations can be programmed into each 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.
Data Acquisition and Tolerance Checking Software
Data is collected and analyzed in real-time to ensure all modules are within the set tolerances. The data points are displayed graphically on the XM display and can also be exported as a .csv file and viewed on a program such as Microsoft Excel. These files can be exported through one of the USB or Ethernet ports on the XM Controller.
Laser Seam Tracking
The XM integrates with a Meta laser sensor to scan and automatically track the joint during welding. The laser continuously scans the joint profile and makes the necessary adjustments to ensure the torch maintains the programmed location. The scanned profile is also displayed in real-time on the operator console monitor. Seam tracking can be configured for single or multi-pass welds.
AVC for GTAW/PAW System
An AVC (Arc Voltage Control) Module is added to provide the weld head with automatic arc standoff. The module provides automatic height adjustments to maintain a consistent arc voltage throughout the entire weld, including automatic adjustments on multi-pass welds.
Camera System (SAW)
A video camera and cross-hair laser generator are mounted to the weld head to aid in monitoring during welding operations. The video feed is displayed in real-time on the operator console monitor. The camera is also used to aid in positioning the torch(es) during setup.
We integrate components into our controls for automating additional functions other than the welding process. These components include safety equipment such as automatic weld screens or curtains that are programmable to automatically open and close at the end or beginning of each weld. We can also integrate additional tooling such as automated part loading equipment.
Multiple Process Weld Head
Our advanced controls allow us to integrate multiple weld processes into one weld head. Each process can be operated independently or simultaneously. For example, a TIG & Plasma weld head would feature two AVC axes (one for each torch) and either torch could operate or they can both operate simultaneously for Keyhole Plasma with a TIG trail. We offer TIG & Plasma, TIG & MIG, TIG MIG & Plasma, and SAW & MIG. Any of these combinations are available and would be completely programmable from ONE central controller. Other combinations are also available. Please contact us with any requests.
Multiple Wire Weld Head
AMET specializes in offering custom weld heads. We offer GTAW and PAW weld heads with two wires. The wire feeders can be synced to operate simultaneously or they can be separated to operate independently. We also offer multiple wire SAW head welds. Up to 10 wire weld heads can be integrated with our control packages for applications such as cladding. Heads with 3 wires are available for thick wall welding applications.
Single Point Power Distribution
AMET provides fuse-protected power to all system components from a single primary power circuit (provided by customer).
Coordinated Motion Module
Up to four motion axes can be integrated together. This allows each axis to function and coordinate together, much like the axes of a CNC milling machine, to perform welds on unique part geometries.
Virtual Alignment (Teaching Mode)
The operator can “teach” a weld path by manually moving the weld torch along the seam and selecting points. Up to 20 points can be selected to create a circumferential, longitudinal, or combination weld path. After all of the desired points are selected, the system will retrace each one to create a custom weld path. This can be helpful if parts or materials vary or have unique joint configurations. The path can be repeated for multiple pass welds, or offsets can be applied to repeat the motions of the original path in a new location.
Flux Delivery and Recovery System
The entire system is air-pressurized and heated to provide continuous flux delivery and recovers unused flux to help reduce costs. The system consists of a feed tank, delivery and recovery unit with 5 HP vacuum, and hopper for delivery at the weld head. The hopper is equipped with a valve to allow the operator to control the ratio of new and recovered flux delivered at the weld head.
AMET manufactures a full line of high precision turn tables with weight capacities from 550 to 22,100 lb (250 to 10000 kg). We also offer standard version turn tables with weight capacities from 2,200 to 132,200 lb (1000 to 60,000 kg). Each turn table faceplate includes a thru-hole for a gas purge device.
AMET manufactures a wide range of positioners with weight capacities from 550 to 22,000 lb (250 to 10000 kg). They feature 135 degrees of motorized tilting and continuous motorized rotation. The rotation axis can be integrated with the XM to provide programmable control for welding operations. High-precision models are also available with harmonic drive rotation for the most stringent needs. The standard configurations include a fixed base, but an elevating base is also available. Each positioner includes a thru-hole for a gas purge device.
Programmable Gas Control
Adds programmable gas flow control for GTAW and PAW applications.
AMET manufactures fit-up stations for aligning two sections prior to welding. The fit-up stations feature four (4) wheels that are controlled hydraulically. The wheels are divided into pairs A & B and C & D, and there are several options for moving them to accommodate a wide range of applications. The following motions are possible: each wheel can be moved independently (in/out from the centerline), each pair can be moved simultaneously (in/out or side-to-side), or all four wheels can be moved simultaneously. The fit-up station can also be mounted on a rail system and have motorized motion in a growing line system.
The precision boom option upgrades the horizontal motion of the manipulator boom with a servo motor and encoder, which is integrated with the XM Controller. This provides the boom with welding axis quality motion for longitudinal welds.
Arc initiated by touching the torch tip to the part for GTAW and PAW applications.
A precision servo motor driven ball screw slide with encoder feedback provides mechanical oscillation. The oscillation motion is completely programmable including dwell time, oscillation frequency and width, and travel speed.
Magnetic probe is used to deflect the arc back and forth in a stirring motion for excellent sidewall tie in. The arc can also be deflected and maintained in a set position. This can be beneficial for fillet or otherwise hard-to-reach joints. Dwell time, oscillation frequency, and width are all programmable from AMET controls. Compatible with both magnetic and non-magnetic materials.
Spiral Path and Step-Index Cladding
The vertical or horizontal axis is integrated with the rotary axis to provide precise cladding motion. We offer both Spiral Path, and Step-Index cladding options. Spiral welds begin at the bottom of the part and spiral upward until the defined height is reached. Step-Index clads in a straight line for each revolution of the part. After each revolution is completed, the torch steps upward and begins the next pass. The pitch of the spiral and the step height are programmable.
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.
AMET offers several sensors to monitor several functions and aspects of the weld. Each one of these sensors can automatically terminate the weld program if levels exceed the set parameters. The following sensors are available:
• Humidity Sensors – measures humidity levels at the weld puddle
• Oxygen Sensors – measures oxygen levels at the weld puddle
• Water Sensors – monitors water flow for components such as torches
• Gas Sensors – monitors gas flow for shielding/backing/purging gas
Integrated Purge/Backing Gas
This package includes a gas union, digital solenoid, manual flow meter, and a gas line from the solenoid to the gas union for purging or backing gas capability. The digital solenoid is integrated with the XM for programmable and manual on/off control of the gas. Programmable flow control is also available.
Weld programs and data can be transferred between a PC or sever and the XM Controller wirelessly.
Bar Code Program Selection
Weld programs can be automatically selected by scanning a bar code associated with a specific part. This can help eliminate the incorrect program being loaded and run. Beneficial if many different parts are to be welded and operator needs to frequently switch between weld programs. Includes the bar code scanner and the necessary software to integrate with the XM Controller.
