Ekonor: Solutions for pipe-welding.

Westfalen AG has been dealing with manufacturing components for pipeline construction for over 20 years.

The focus is on orbital / pipe circumferential welding, but as a special machine builder, we have also implemented other applications according to customer requirements.
The heart of many systems is our internal clamping system, which enables simple alignment, clamping and purging of the components and in most cases does not require the time-consuming tacking process. This saves around 50% of the total production time, regardless of the welding process.


Panther Flexible.

The entry-level model of the pipe-welding machine.

Can be combined with internal clamping device, cold wire, AVC and oscillation. The user-friendly EKOTRON control is used.

  • Pipe length  30 – 6000 mm
  • Pipe diameter from 1“ – 8“, on request up to 16 “
  • Wall thickness from 1 – 15 mm

EKONOR control system:

  • simple and user-friendly menu navigation
  • all relevant welding parameters can be programmed and stored
  • data documentation and transmission possible.

Internal Clamping Device:

  • optimal setup, centring and forming
  • quick change to other nominal widths
  • no tacking and no gas pre-flow required

Options:

  • arc voltage control
  • cold wire feed
  • torch weaving
  • further system components for pipe handling

Panther Flexible – TIG-Power Source.

  • modern inverter power source with pulse technology
  • power can be selected as required (200/350/500 amps)

Panther Hybrid.

The Panther-welding machine is used for automated welding of flange joints with different fittings. The system drastically reduces overall manufacturing times, with improved seam quality.

The internal clamping device (ISV) allows welding without an air gap and without tacking. The ISV is also used to purge the root of the weld, so there is no prepurging time.

  • Pipe diameter from 1“ – 16“, on request up to 16 “
  • Wall thickness from 1 – 15 mm

Advantages:

Cobra.

The TIG/MAG butt-welding machine is used to automatically weld pipes and fittings to each other. This version of the machine is used for longer pieces of pipe, which are delivered to the machine on the automated transport system. The system drastically reduces overall manufacturing times, with improved seam quality.

This machine uses an internal clamping system, which is inserted into the pipe and fitting to align them and allows for zero-gap welding without the need to tack-weld. Depending on the WPS the bevel will either be a V groove or a J groove, with a 2 mm root face.

The pipe is moved onto the infeed supports using transfer arms mounted on the buffer table. These arms deposit the pipe on the supports, which then move it into the chuck. Once the pipe is clamped in the chuck, the mandrel carriage moves forward to insert the mandrel with the inner clamping device into the pipe.

When the mandrel is in position, the operator uses a foot switch to engage the first clamp. Then the fitting is moved into position, either by hand or, for heavier fittings, by crane. The operator then engages the second clamp, holding the fitting in place, and initiates the welding process.

The root run of the joint will be welded with TIG. Afterwards additional layers of TIG or MAG will be welded, according to the established WPS.

  • Pipe length  30 – 6000 mm
  • Pipe diameter from 1“ – 16“
  • Wall thickness from 1 – 20 mm

Advantages:

  • simple and user-friendly menu navigation
  • all relevant welding parameters can be programmed and stored
  • data documentation and transmission possible.
  • optimal setup, centring and forming
  • quick change to other nominal diameters
  • no tacking and gas pre-flow required

Options:

  • arc voltage control
  • cold wire feed
  • torch weaving
  • further system components for pipe handling

Scorpion.

The MAG-welding machine is used to automatically weld slip-on flanges or sleeves to pipes. The loading and unloading of pipes is automated, loading of flanges / sleeves is manual.

The pipe is transferred to the machine from the buffer table using movable transfer arms, which roll the pipe onto the machine’s pipe supports. These pipe supports then align the pipe with the flanges and move the pipe into position inside the first turn-table, while the second turn-table follows until both flanges and the pipe are properly aligned and positioned.

Then the second set of torches moves into position, and all four seams are welded simultaneously.

After welding the torches retract and the pipe is ejected onto a table or conveyor.

For sleeves the process is similar, however the machine only welds the outside seams, not the inside.

The MAG welding machine can weld the following connections:

  • Min. pipe length: For simultaneous welding on both sides 400 mm. For sequential welding (one side after the other) 100 mm. 
  • Max. pipe length: 6,100 mm
  • Pipe diameter: 48.3 – 406.4 mm
  • No. of welding torches: 4
  • Automated tacking if necessary
  • Simultaneous welding of all welding seams
  • Full integration with workshop control software
  • Signal exchange with transport system
  • Data-Exchange with workshop software (Pipe / Spool ID, pipe diameter, status update when completed)

Double working pneumatic clamping device.

From Westfalen devolped clamping devices deliver a great benefit for pipe production. The numerous advantages simplify the pipe fitting in the workshop or on site and reduce the costs over 60 %.

  • No tacking
  • Optimal setup of the pipe parts via separate clamping (double cylinder)
  • Gap-free adjustment of the pipe parts to be welded together
  • Automatic centering of the pipe formed parts
  • Minimises ovality tolerances
  • No subsequent handling of the workpieces (root free of tempering discoloration)
  • Greatly reduced consumption of forming gas (small forming gas chamber/no gas pre-flow time)
  • Can be used flexibly as a mobile building site tool or in pipe manufacture
  • Clamping range of 1” – 16” mm internal diameter

Our Services.

Maintenance.

Maintenance is better than repairing. That is why we offer our customers a wide range of maintenance options. From overhauling the systems in our factory to tailor-made maintenance contracts and on-site maintenance.
The maintenance contract can include both the mechanical and electrical testing of our systems. Make use of these possibilities, because the longevity is also a factor for the profitability of the system.

Repairing.

Despite high-quality system technology, repairs cannot always be avoided. In this case we offer quick and competent help. We ensure that your system is quickly ready for use again. Due to the modular structure, the system can still be partially operated in a restricted form. With a sensible storage of spare parts, many repairs can be done by yourself.

Renting service.

Renting a system is a good opportunity, especially for beginners, to experience the advantages of automated welding. The costs can be written directly to the project and extensive investment planning can be omitted. We offer a wide range of rental systems, whereby the rental costs can also be partially offset against a later purchase.
