Advantages

AMET manipulator systems offer robust solutions for a wide range of applications with the following benefits:


  • The XM Controller is at the center of the system. It integrates into all of the main welding equipment and precision axes of motion for control over welding operations.
  • The control components and software are produced in house. This ensures compatibility and also decreases the possibility of obsolescence
  • Supports a variety of welding processes including: GTAW, PAW, GMAW, FCAW, VPPAW, VPGTAW, and some SAW applications. Dual process is also available such as GTAW & PAW or SAW & GMAW.
  • The large range of motion and weight capacities ensures AMET can provide a manipulator system to suit many project needs.
  • Integration of camera systems. AMET offers camera systems for arc viewing (GTAW/PAW) applications and standard cameras for SAW applications. The cameras offer advantages such as aiding in positioning of the weld head and manual seam tracking. This can be especially beneficial on large parts where the weld joint is not easily accessible.

These manipulator systems are highly customizable to meet the needs of our clients. A motorized turntable or positioner can be paired with a manipulator to provide bore cladding or circumferential welding capabilities. For welding larger parts, a full line of turning rolls and growing lines are available. Manipulators can also be mounted to a travel cart for performing longitudinal welds.

  • Rotation Control - The XM is capable of integrating with and controlling the following rotary equipment:

    • Turn Tables
    • Positioners
    • Turning Rolls

  • Linear Motion Control- The XM can integrate with and control the following motion devices:

    • Vertical Motion: A precision motorized slide can be added to the weld head for vertical torch adjustment. This axis is available with AVC for GTAW and PAW applications.
    • Horizontal Motion: A precision motorized slide can be included for cross-seam adjustment. A servo motor can also be added to the boom axis for programmable control. The manipulator can be equipped with a motorized travel cart for performing longitudinal welds.

  • Integrates with the welding power supply to control all parameters from the XM screen.

Standard Features on Column and Boom Manipulator Systems


1

A weld head is attached to the end of the boom, which typically includes two precision motorized slides for moving the torch vertically and horizontally. Torch tilting, pivoting, and lead/lag adjustments are available to accommodate most types of weld joints.

2

The motorized boom features thick wall steel construction that is stress-relieved to extend the life and increase the precision of the manipulator. The boom is equipped with a variable speed motor for in/out horizontal motion.

3

Vertical boom motion is provided by a fixed speed motor with a brake to prevent unwanted movement. The manipulator features a heavy-duty chain drive to move the boom up/down and an anti-fall safety device to prevent the boom crashing to the factory floor should the chain lift fail.

4

Cable carriers are included on both axes to extend the life of the cables and hoses. The carriers also keep the cables organized and prevent entanglement during operation.

5

THK style rails are included for the entire length of the column and boom motions. The rails coupled with recirculating bearing blocks ensure smooth operation throughout the life of the manipulator.

6

The column features a kingpin for 360 degrees of manual rotation with four manual brakes to lock the column into postion. A handle is included on larger manipulators to aid in rotation.

7

A sturdy freestanding base supports the manipulator fixture. Each leg of the base includes a hole that can be used for anchoring the manipulator to the factory floor for additional stability.

Optional Features on Column and Boom Manipulator Systems


Offline programming
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.

Turn rolls
Turning Rolls

AMET offers a full line of turning rolls for part rotation with weight capacities from 2.5 to 150 ton. The turning rolls can either be operated independently for positioning purposes, or integrated into the welding system through the XM Controller for controlled and programmable part rotation

Amet camera light attached smaller
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 acquistion
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 can be displayed graphically on the 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 or XPro Controller.

Laser tracking unit
Laser Seam Tracking

The XM or XPro integrate with a laser sensor to scan and track the weld 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 module
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   monitor saw
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.

Tig   plasma head
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.

Sppd opt
Single Point Power Distribution

AMET provides fuse-protected power to all system components from a single primary power circuit (provided by customer).

Virtual alignment
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.

Travel cart with rails 1
Travel Cart with Rails

Manipulators can be mounted to a travel cart for increased capacity. The travel carts are typically motorized, but are available as non-motorized units for our two smallest classes of manipulators. The motorized travel cart can be operated independently for positioning purposes or upgraded and used as a welding axis for longitudinal welds.

Equipment platform cleaned
Equipment Platform

The travel cart can be extended for mounting the weld equipment next to the manipulator to keep everything centrally located. This helps eliminate excess cabling and reduces trip hazards.

Flux system
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.
