Welded fabrication
MGR Monnier Energies has been bringing its welded fabrication expertise to many industrial customers for 25 years
High-quality welded fabrication for the nuclear, energy and aerospace sectors and many more across Europe
With 25 years’ expertise in welded fabrication, large part machining and light and heavy sheet metal work, we serve customers in the nuclear, energy and aerospace industries, as well as special machine builders.
Our workshop equipment enables us to work with thicknesses from 10 to 120 mm and to handle welded assemblies weighing up to 10 tonnes.
Our fitter-welder teams carry out the assembly and welding entrusted to them with close attention to part geometry and clean workmanship, ensuring, for example, good paint adhesion and a high-quality final finish.
We supply customers throughout France, Germany, Switzerland and elsewhere in Europe.

Definition: what is welded fabrication?
Welded fabrication involves joining metal parts together by welding. By assembling different components, it is possible to produce large, complex structures that would be difficult to make by other methods. This technique allows very large parts to be welded together to produce, for example, frames designed to support heavy loads or handling systems.
It also ensures exceptional strength in the finished structure, making it possible to manufacture parts that are both light and rigid.
Various welding processes can be used:
- TIG welding (Tungsten Inert Gas) for precision work and finishing.
- MIG welding (Metal Inert Gas) or MAG welding (Metal Active Gas), on the other hand, is ideal for assembling structures.
Welded fabrication is a good alternative to castings and produces robust, high-quality parts at lower cost.
MGR supports your one-off and small-batch welded fabrication needs
We manufacture welded assemblies in small batches or as one-offs, which may require welding qualifications. To this end, our workshop is fitted with modern, regularly maintained equipment. Our teams take pride in meeting the demanding metallurgical control requirements of this work.
We also attach great importance to our working environment, which features a central welding fume extraction system and fume extraction torches.

A complete service for producing welded assemblies
Our welded fabrication service covers fabricated plate parts, mainly in steel.
Working in partnership with our customers, we design and develop welded assemblies to meet all kinds of industrial requirements. For example, MGR produces numerous tubular frames for special machine builders.
Our teams also excel in manufacturing chassis, lifting beams and tooling for the nuclear industry, produced under qualification.
To guarantee production quality, we carry out non-destructive testing (NDT) on our welded assemblies in-house, thanks to our certified staff.
Finally, by working with our surface treatment partners, we offer a complete, end-to-end service covering all your needs.
Our workshop is fully equipped for high-quality welded assemblies
Our workshop is equipped with:
- 8 MIG MAG welding stations (2.5 kW per station)
- 2 pulsed MIG MAG welding stations for aluminium
- 2 TIG welding stations (including 1 × 500 A station at 100% duty cycle)
- 1 automatic submerged arc welding tractor
- 1 plasma cutter
- 1 laser cleaning unit
Handling equipment:
- 1 overhead crane, max. load: 10,000 kg
- 1 overhead crane, max. load: 6,000 kg
All these welded assemblies are produced with a constant focus on improving the working environment. The welding stations are fitted with fume extraction torches, and the workshop has a general extraction system that renews the air every 30 minutes.
French know-how recognised by our major industrial customers
One of our core skills, welded fabrication for industry, is recognised in France and has crossed borders to our European customers.
The French government’s recognition of our quality as a manufacturer is illustrated opposite by the visit of Laurent Pietraszewski, Secretary of State for Pensions and Occupational Health to the Minister of Labour, who toured our welded fabrication workshop, and by our meeting with Bruno Le Maire, Minister for the Economy, Finance and Recovery, during Emmanuel Macron’s visit to our customer General Electric’s site.

Welded fabrication for the energy and nuclear sectors and special machines
Our teams are organised to meet our customers’ demanding requirements.
Welded assemblies for the energy and nuclear sectors
For the nuclear sector, we have organised our operations to comply with the requirements specific to this industry. Our fitter-welders are qualified, and non-destructive testing (NDT) expertise is partly integrated within our teams.
MGR excels in manufacturing welded chassis and maintenance tooling for nuclear power plants.
Welded fabrication for special machines
We produce numerous tubular frames for special machine builders.
MGR can also work for other industries such as aerospace, automotive and defence.
A team of 8 welded assembly experts
Our team comprises 8 people: welder-fitters, COFREND level 2 certified NDT inspectors and welding technologists (IWT)
Passionate about their trades, they regard passing on their skills as essential. This is why the company places great importance on taking on apprentices, particularly in its welded parts workshop.
At MGR, quality is essential for all our teams
ISO 9001 and ISO 3834-2 certified for our welded fabrication activity, we are committed to ensuring a high level of quality in the welded frames we produce. Our teams are particularly aware of this issue, so you can count on a result that meets your expectations, however demanding your industry.
Your welded assemblies delivered throughout France and Europe
Located in eastern France, in the Territoire de Belfort, bordering Germany and Switzerland, we can transport your welded structures ourselves depending on your location.
Through our logistics partners, we also deliver to every region of France and to other European countries.
