INDUSTRIAL WELD LATHE SYSTEMS

process accuracy in a robust proven package

Industrial weld lathe systems are used to produce high quality welds on circumferential (girth) weld joints for large sale components in a variety of parts and part shapes. The weld joints can have various configurations, including butt, fillet, overlap, and joggle. Welding is typically performed from the external side of the weld joint, but internal welding is also available for special applications. Single and multi-pass circumferential welding (c seam welding) can be performed using GTAW, PAW, VPGTAW, VPPAW, GMAW, FCAW, or SAW welding.

Coupled with our advanced weld controls, the lathes are highly customizable and versatile. They are configurable for circumferential welding  (c seam welding), OD cladding, and even longitudinal welding. Additional weld heads can also be added so multiple welds can be performed simultaneously.

30+ Years of welding Automation Excellence

AMET’s Industrial lathes are offered in a wide range of weight and length capacities. Lathes can be customized to meet additional needs, but the following are the general specifications of the standard lathes:

  • Weight Capacity: The headstock and tailstock combine to provide a weight capacity from 1,100 to 22,000 lbs (500 to 10,000 kg).
  • Length Capacity: Maximum part lengths are from 23.6 to 283.5 in (600 to 7200 mm). These capacities are the maximum lengths between the headstock and tailstock faceplates. The addition of tooling reduces these capacities.
  • Diameter Capacity: Maximum part diameters (OD) are 35.4 to 59.1 in (900 to 1500 mm).
  • Headstock Rotation: Programmable and continuous rotation are included on all models.
  • Tailstock: The tailstock is manually adjustable along the length of the lathe. It features idler rotation, a faceplate with four (4) t-slots for tooling, and pneumatic clamping with a maximum stroke of 5.9 in (150 mm).
  • Carriage Motion: Manual motion is standard with a hand brake to lock the carriage into position. Motorized motion for positioning and precision motion for longitudinal welding are also available.

     

    Additional features are available. Please refer to the Optional Features section for more information.

AMET Industrial Weld Lathe systems offer several benefits over manual and non-automated welding, including:

  • With AMET’s programmable control of the headstock rotation, welds are more consistent. Consistent welds decrease the need to finish the part after using grinders or other methods of enhancing part appearance.
  • With the programmable motion of the weld head, multi-pass welds can be performed without the need to stop after each pass is completed.
  • Weld programs are saved in the controller, so setup times are reduced and productivity is increased.
  • Tailstock clamping can reduce or even eliminate the need for tack welding. This improves the quality of the weld and decreases cycle time for each part.
  • Operator involvement is decreased which increases weld consistency and reduces fatigue.
  • The combination of these benefits reduces the time to prepare a part, the time to finish a part after welding, and preparing the system for welding. Rework time, part scrap, and consumables costs are also minimized to increase efficiency.

XM® Controller
The XM® Controller integrates into all of the major programmable components of the lathe. The following axes of motion and components are integrated into the system:

  • Headstock Rotation: The Rotary Module integrates with the servo motor driven headstock to provide programmable motion with override capabilities. The rotation can be programmed by degrees, RPM, or time. Continuous and jogging rotation are also available through the control panel on the XM®.
  • Weld Head Vertical Motion (Z-Axis): A precision slide driven by a servo motor provides programmable vertical motion with override capabilities.
  • Welding Power Supply: The power supply is integrated with the XM® via a module for programming and controlling the current or voltage.
  • Gas Control: Manual flow meters and a gas solenoid provide a constant gas flow rate. A soft button activates gas at the default flow rate until the button is deactivated or until the end of the weld program.
  • Wire Feeder: AMET’s precision wire feed assembly and wire feed module offer control over wire speed and wire retract.

Pneumatic Control:

  • Tailstock Clamping: Clamping force adjustable with a stroke up to 3 in (76 mm)

Manual Control:

  • Carriage Motion (X-Axis): The carriage is manually adjustable along the length of the track with manual brakes.
  • Centerline Adjustment (Y-Axis): A manual slide with a manual brake is included to provide centerline adjustment of the weld head. Both the X Axis and Y Axis can be upgraded to motorized motion.

Additional Carriage for Welding
ADDITIONAL CARRIAGE

An additional carriage can be added to the system to provide two (2) weld heads. This option allows two welds to be performed simultaneously or sequentially for increased productivity.

 

 

 

 

 

PLC Controls
PLC CONTROLS

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.

 

 

Mechanical Oscillation

MECHANICAL OSCILLATION

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.

 

 

 

 

Offline Programming SoftwareOFFLINE 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.

 

 

 

 

 

Synchronized Headstock and Tailstock
SYNCHRONIZED HEADSTOCK AND TAILSTOCK

This feature adds synchronized rotation between the headstock and the tailstock, so rotation begins simultaneously and then continues at the same speed. The advantage of this feature is that AMET® does not link them mechanically but electronically. Each one is servo motor controlled with encoder feedback, so they can be clocked to different positions. This is beneficial if one end of the part is required to be welded at a 90 (or any other) degree offset of the other end.

 

 

Multiple Process Weld 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.

Megnetic Oscillation

MAGNETIC OSCILLATION

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.

 

 

 

 

Power Tailstock TravelPOWER TAILSTOCK TRAVEL

A motor and friction drive assembly can be added to provide motorized linear motion of the tailstock along the length of the base. The motion is controlled by a hand pendant attached to the tailstock and would be used for positioning purposes only. This also includes the hydraulic braking option to lock the tailstock into position.

 

 

 

 

Arc Viewing CameraARC 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.

High Precision Headstock

HIGH-PRECISION HEADSTOCK

Upgrades the motorized headstock rotation with a higher precision gearbox for reduced backlash. This option is beneficial for complex operations such as intersecting bore cladding.

 

 

 

 

 

Grippers and ChucksGRIPPERS 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.

 

 

 

 

 

Multiple Wire Weld Head
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. Tandem or triple wire weld heads are also available for thick wall welding applications.

 

 

 

 

 

 

 

Spiral Path and Step Index Cladding
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.

 

 

 

 

Data Acquisition and Tolerance Checking SoftwareDATA 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.

 

 

 

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.

 

 

 

Bar Code Program Selection
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® or XPro Controller.

 

 

Chuck Added to Headstock/Tailstock

CHUCK ADDED TO HEADSTOCK/TAILSTOCK

A manual chuck or gripper can be added to the headstock or tailstock faceplate to provide manual part gripping/holding.

 

 

 

 

 

AVC For GTAW/PAW System

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.

 

 

 

 

 

 

 

Integrated ID Purge/Backing Gas

INTEGRATED ID PURGE/BACKING GAS

The headstock includes a thru hole for adding backing gas or purge gas capability. This package includes a gas union, digital solenoid, manual flow meter, and a gas line from the solenoid to the gas union. The digital solenoid is integrated with the XM® or XPro for programmable and manual on/off control of the gas.

 

 

Motorized Travel Carriage for WeldingMOTORIZED TRAVEL CARRIAGE

Motorized and precision motorized motion of the carriage are available. The motorized option is for rough weld head positioning, while the precision option provides programmable positioning and can be used for longitudinal welding. Limit switches are included for both options, and the precision option includes a home switch.

 

 

 

TILTING HEADSTOCK

Adds motorized tilting of the headstock from 0 (faceplate horizontal) to 90 degrees (faceplate vertical) with an attached angle indicator. A hand pendant is included to control the tilting motion.

 

 

TAILSTOCK HYDRAULIC BRAKING

Replaces the manual brakes for the tailstock linear motion with a hydraulic unit to lock the tailstock into position and prevent unwanted movement during operations. The manual brakes are sufficient to hold the tailstock in place, but the hydraulic brakes operate more quickly saving time and increasing productivity.
