An increase of more than 30% in your productivity rate
As orbital welding is much less labour intensive than manual welding, a welding operator makes 30% more welds per day on average when using orbital welding equipment.
Since the weld presents a regular geometry without overlay it does not need to be ground or cleaned.
The welding operator can engage in other activities during the welding phase.
Low reject and repair rates.
Due to the repetitive aspect of the process, weld defects are less likely to occur.
Extremely simple to use
The operating process for the equipment is mastered in less than one day's training.
A self-programming system and standard program library are included with the power source, making it easy to adapt programs to each type of application.
Manufacturing methods easily adapted to the work load
The equipment is extremely simple to use. This means that welding teams could quickly be expanded in the case of increased demand.
If you do not have enough equipment to absorb your peak work loads, simply call our rental department.
Less space required for your installations 
TIG orbital welding allows you to keep ahead of competitors who still use manual welding techniques.
Aeronautics – Aerospace / Defence
Various application fields
Transportation of liquids (hydraulic, carburant)
Propulsion systems (Nuclear and conventional)
Measuring systems
Increased lifespan through high quality cladding
Mechanical construction – heavy wall high resistance welds 
Materials that improve the characteristics and lifespan of your products 
The implementation of adapted automatic welding processes enables to control and limit the amount of heat input required. 
Permanent control of the heat input 
The principle of the entire weld control avoid as much as possible the deformations. You can adapt the welding program to each individual situation. Torch movements, welding current and wire speed, for example, may be synchronised.
The best quality – repeatedly 
In automatic welding, repetitive quality is absolute. Thus there will be no manufacturing flaws.
A minimum number of rejects and repairs 
Thanks to the excellent repeatability of the automatic welding process, rejects can be reduced to a minimum. The high adaptability of our equipment and software packages enables you to weld various components using the same equipment.

Thermal transfer equipment – heat exchangers

Nuclear applications
Power generation / Petrochemical industry
TIG hot wire increases the deposit rate by more than 3:1
Compared to TIG cold wire orbital, TIG hot wire orbital welding is particularly advantageous for medium and heavy wall thicknesses.
Combined advantages of TIG hot wire and narrow gap techniques
The combined effect of increased deposit rate and reduced bevel angle, allows a significant rise in productivity compared with an open bevel angle in TIG cold wire application.
The right welding procedures
The "large bevel" welding technique is quite flexible
Standard preparations used for TIG cold wire welding are generally large bevel preparations such as V or J grooves.
Welding with oscillation and single layer passes is used where the wall thickness is less than 20 mm.
Welding with a large bevel is advantageous as it can support many different configurations and applications. Mixed bevel types (i.e. elbow joints) can also be used with this type of preparation.
Welding with "narrow gap" preparation (NG) gives an important increase in productivity
This rise in productivity is achieved by decreasing the amount of weld metal to be deposited. If we compare the weld volume of a narrow gap bevel to a classic preparation type 37° compound bevel on a 60 mm wall thickness pipe, this gives a volume saving in favour of narrow gap by a factor of 1:3.
The only way to do internal bore welds, on double plates or at the back side of the Tube-sheet (Petrochemical ind.)
Our equipment makes it possible to weld in confined spaces, thus optimizing layout designs.
