High coordination effort between design and manufacturing
Often, the link between technical drawings and actual implementation is missing. STW handles the complete manufacturing of your welded assemblies based on your design data – including technical queries, feasibility analysis, and suggestions for production optimization.
Shortage of qualified personnel for welding work
Whether MIG, TIG, or orbital welding: the shortage of skilled workers is directly affecting many companies. As a certified welding company according to DIN EN ISO 3834-2 and EN 1090-2, we offer you verified expertise, experienced skilled workers and reliable processes – for consistently high quality, even in series production.
Lack of quality assurance and traceability
Documentation is crucial, especially for complex welded structures. We deliver upon agreement. Complete test reports, material certificates, welding datan and Measurement checks Everything is documented, archived, and traceable. This ensures you meet industry-specific requirements and audit specifications.
Unclear responsibilities in component assembly
Time losses often arise from interface problems between raw materials, welding technology, and assembly. At STW, you receive assemblies that are fully assembled, tested, and ready for installation – all from a single source, with one point of contact.
Difficulties in the mass production of complex components
Small production runs or recurring welded parts are demanding in terms of planning, logistics, and execution. Our combination of modern machinery, standardized processes, and precise workmanship allows us to deliver reproducible results – quickly, reliably, and with consistent quality.

FAQ – Welded assemblies explained in simple terms
Welded assemblies are pre-assembled structures or components made up of several metal parts joined by welds. They enable rapid integration into machines, plants, or systems – without additional on-site welding work.
We manufacture from and with stainless steel – depending on the application, requirements and environment. We rely on tested materials and documented processing according to DIN EN ISO standards.
We use TIG welding for fine, clean joints, MIG welding for high-volume production, and orbital welding for recurring pipeline seams. All processes are certified and designed for industrial series production.
Our welded assemblies are used wherever robust, dimensionally accurate and durable stainless steel constructions are required – in mechanical engineering, pipe installation and process engineering.
Each assembly undergoes visual inspection, dimensional checks, and – depending on requirements – endoscopy or other methods. This ensures repeatability, leak tightness, and long-term durability.
