Renewable energy investments are growing fast worldwide and in Türkiye. Welding for the energy sector — wind turbines, solar structures and hydropower facilities — demands work with high-strength steels under tight quality requirements. ArmaWeld manufactures structural components and cabinets for the energy industry from Konya.
1. Wind Turbine Components
In wind turbine production, tower flanges, foundation structures and nacelle internals are welded fabrications. Steels with low-temperature impact toughness such as S355 NL, S420 NL or S460 NL are typically used.
- Tower segments: SAW (121), inside and outside passes
- Flange welds: full-penetration, 100% UT
- Nacelle internal frames: MAG (135) and robotic welding
2. Solar Energy Structures
In solar (PV) plants, the main load-bearing structures are typically galvanized S275/S355 sections. Welded manufacturing comes into play in transformer cabinets, monitoring structures and connection details. EN 1090 EXC2 is the standard execution class for these projects.
3. Hydro and Thermal Applications
| Application | Typical Material | Process |
|---|---|---|
| Penstock | S355 / S460 | SAW + UT |
| Turbine casing | P355 / P460 | SAW + RT |
| Boiler element | P265GH / 16Mo3 | TIG root + SAW |
| Cooling towers | S235 / S275 | MAG (135) |
4. Quality and Certification
For energy projects, EN 1090 EXC2/EXC3, EN ISO 3834-2 and PED 2014/68/EU are typical scopes. For pipes and pressure equipment, every welder is qualified per PQR; SAW machine settings are recorded. ArmaWeld links every weld to its digital traceability infrastructure for energy projects, delivering a complete QC package to the customer.
