Machine factory in Enschede, since 1992
Our vision on welding
High-quality welding requires craftsmanship, precision, and a controlled production process. In our welding shop, we combine experienced welders with modern welding robots and certified processes. This allows us to realize both complex custom constructions and recurring series with consistent and reliable quality.
Welding according to EN ISO 3834-2 for demonstrably assured quality. Welding up to 50 m.
Automated welding for high reproducibility and consistent quality.
Craftsmanship for custom work, complex connections, and flexible welding.
Jig system developed by Delwi that allows multiple parts to be robotically welded simultaneously.
Craftsmanship and automation under one roof
Within our welding shop, we combine manual and robotic welding for both custom and serial production. By selecting the right welding method for each product, we achieve an efficient production process with consistent quality. Furthermore, our welding shop connects directly to sheet metal working, machining, coating, and assembly.
01
Consistent quality through smart automation. With modern welding robots, we produce welded structures quickly, accurately, and reproducibly. Robotic welding is ideally suited for recurring products and series where consistent welding quality is paramount.
For automated welding, Delwi has four Cloos robotic welding systems: two Cloos GLC 353 systems, a Cloos QRC 350-E, and a Cloos R450. Thanks to various configurations, workstations, and manipulators, diverse welded structures can be processed automatically.
The largest installations are suitable for products up to 6000 × 3000 × 3000 mm and 5000 kg. For serial welding, we also utilize our own 0-Span system, which allows multiple parts to be efficiently positioned and robotically welded.
02
Craftsmanship for flexible and complex welding. Not every structure lends itself to automation. Our experienced welders provide manual welding for custom steel structures, one-offs, and complex constructions where flexibility and craftsmanship are essential.
Manual welding offers the flexibility to create a wide range of structures, materials, and connections. Our welders work according to established welding procedures and possess the knowledge and experience to reliably execute even more complex assemblies.
We work with welding processes 135 (MAG welding with solid wire) and 138 (MAG welding with flux-cored wire), among others.
03
Quality demonstrably assured. Our welding is certified according to EN ISO 3834-2:2021, the standard for comprehensive quality requirements in the fusion welding of metals. As a result, quality is not only visible in the end product but demonstrably assured throughout the entire welding process.
The certification covers welding on S235 to S355 (material group 1.1–1.2) and S690QL (material group 3.1), with welding processes 135 and 138.
From welding procedures and qualified personnel to quality control and documentation: the quality of our welding is systematically monitored throughout the production process.

Conscious production
With 2,444 solar panels, smart energy systems, and multiple disciplines under one roof, we are continuously working on a more efficient production process. Moreover, by combining production processes internally, we limit unnecessary transport movements between different suppliers.
