Weld overlay is applied whenever a long service life is expected from expensive components or when the workpiece cannot be produced entirely from the proper wear-resistant material. Weld overlay of piping and manifolds is common in petrochemical industry applications and for power plant equipment; in the aeronautic industry, components for aircraft engine components are also often reinforced using this process.

The TIGer technology is the outcome of a technological development by POLYSOUDE, a variant of TIG Hot Wire cladding. The basic principle involves the juxtaposition of two TIG arcs, organised and controlled to be combined into one single arc with the calorific value of the combination of both powers, but with characteristics which are unusual for such intensities.

POLYSOUDE provides complete integrated systems to meet all your requirements and handle the most complex applications:

-          Hot / Cold Wire TIG Welding, Plasma welding and process combinations
-          Welding of difficult materials such as titanium, duplex, zirconium, aluminium etc.
-          Heavy wall Narrow Groove welding
-          Combining all kinds and sizes of workpieces, multiaxis manipulators and torch supports

We provide special solutions where the welding torch is moved into position and the work piece is supported by means of a welding manipulator, such as a positioner or rotator. After having selected the most suitable welding process for your application and requirements, Polysoude offers you integrated automated welding systems, using first class welding manipulators and peripherals, combined with modular electro-mechanical components in the form of welding torches, slides, wire feeders etc.

POLYSOUDE provides different configurations of tube-to-tubesheet equipment according to the application and special requirements:

• A closed chamber welding head such as the TS 34 allows the execution of fusion welding without the addition of filler wire.
• An open welding head with AVC configuration such as the TS 8-75 allows the use of multiple welding heads with filler wire by one operator. The electrode to workpiece distance can be programmed and is kept constant without interruption of the weld cycle.
• An open welding head without AVC configuration is particularly suitable for single layer welding. Two layers must be welded in two separate steps.

Polysoude offers modular welding heads which easily adapt to various applications for tube to tube welding and meet the increasing quality requirements for materials which are often difficult to weld:

• Closed chamber welding heads such as the UHP and MW: for precised welding in high purity industries, especially designed for autogenous welding of tubes without filler wire
  
  
• Open welding heads such as the MU IV and MU IV 195 HW: conceived for orbital TIG welding with or without filler wire, can be carried out manually or by means of motorised slides: Arc Voltage Control (AVC) and torch oscillation (OSC)
  
  
• Carriage-type welding heads such as the Polycar 30, Polycar 60, Polycar 60 PLC and Polycar MP: the most versatile torch carrier which travel around the tubes on suitable rails or tracks, which can be mounted on any tube OD from 32 mm (1,3") upwards

Polysoude provides high performance welding equipment for various applications . A power source for orbital applications is composed of several subassemblies with specific functions each:

-          One or two Power Inverters to supply the welding current, and in case of hot wire welding, the current to heat up the filler wire. Today, state of the art sources are of the inverter type
-          Programmable control unit which is generally based on an integrated or external PC
-          Cooling circuit for the torch and the welding and clamping tools
-          Data acquisition system recording each welding sequence

The power sources for orbital welding can be divided in 3 categories with specific fields of application:

• Portable power sources such as the PS 164-2 and P4
• Medium-sized mobile power sources such as the P6 CW and P6 HW
• Full-size power sources such as the PC 600-3
