Welded assemblies · Subcontract manufacturing in East Westphalia-Lippe & throughout Germany
Welded assemblies. Made to your drawings.
Our contract welding service brings your metal parts together into a finished assembly. We select MIG, MAG, TIG or laser welding to suit your component, with cutting and bending available as part of the same project.

Subcontract welding for industry
Welded steel and stainless steel assemblies
Welded assemblies consist of individual parts joined by welding into a functional unit, such as sheets, tubes and profiles for frames, brackets or stands. The key is not just the individual weld, but how fit, distortion and subsequent assembly work together.
Share your drawing, bill of materials and requirements with us. We can combine laser cutting, tube processing, bending and welding into one manufacturing sequence. Our documented focus is steel and selected stainless steels; we check the material and welding requirements for each project.
Short process routes
Cutting, bending and welding at one site in Höxter.

From data to assembly
Four steps to cost-effective manufacturing
Early technical clarification prevents queries during production and provides a reliable basis for the quotation and delivery date.
Send your files
Send drawings, 3D data, bill of materials, material, quantity and target date.
Assess feasibility
We assess welds, tolerances, accessibility, distortion and the appropriate manufacturing process.
Manufacture & Join
Cutting, bending and welding are carried out in a coordinated sequence.
Inspect & Deliver
Components are inspected to specification, finished and prepared for assembly.
For engineering & Procurement
Information that makes quotations comparable
A finished welded assembly involves more than welding time. Define the required scope of supply so that quotations cover the same work.
Drawing revision & Fit dimensions
Include a revision-controlled drawing, bill of materials and material grade. Identify functional surfaces, datums and required tolerances; add 3D data where needed.
Welds & Inspection requirements
Specify weld details, surface requirements and necessary documentation. Special inspections and the applicable certification scope are agreed before the order is accepted.
From cutting to assembly
State whether individual parts will be supplied or whether prefabrication is required. Specify quantity, repeat demand, finishing, surface treatment and target date together.
Welding quality
Certified – with an honest assessment of each component
The certificates define the framework. Before accepting an order, we clarify whether the material, process, execution class and inspection requirements for your specific component are covered.

Factory production control · EXC2Certified factory production control for structural steel components and kits up to EXC2 in accordance with EN 1090-2.
Complete manufacturing process
From flat and round stock to ready to install
In-house prefabrication
Flat components are made by Laser cutting, profiles and tubes by Tube laser cutting. Where needed, this is followed by CNC press brake bending.

Frequently asked questions
Welded assemblies explained
Technical answers for design and purchasing teams, helping you prepare an enquiry we can assess quickly.
Which subcontract welding processes does NN offer?
We use MIG, MAG and TIG welding, as well as a 3,000 W laser welding system. We select the appropriate process according to the material, geometry, weld requirements and quantity.
Does NN manufacture welded assemblies to drawing?
Yes. We work from technical drawings, bills of materials and, where required, 3D data. We assess weld specifications, material, tolerances, inspection requirements and a cost-effective production sequence before quoting.
Which materials can be welded?
Our documented focus is on steel and selected stainless steels. We assess other materials and material combinations on a project-by-project basis.
Are one-off parts and production runs possible?
Yes. We handle one-offs, prototypes, small batches and repeat production runs. For batch parts, we match fixtures and inspection procedures to the required repeatability.
Can NN also handle cutting and bending?
Yes. Sheet and tube lasers, CNC bending, welding and assembly are available at one site. On request, we can therefore supply a fully manufactured assembly from one source.
Which welding certifications does NN hold?
NN is certified to DIN EN ISO 3834-3. Certified factory production control covers structural steel components and kits up to EXC2 under EN 1090-2. The specific welding scope is defined by the accompanying annexes and welding certificates. We assess applicability to your particular component.
