Hydraulic and pneumatic systems are the power-transmission backbone of construction equipment, agricultural machinery, cranes and special machines. Hydraulic welded manufacturing requires combined pressure resistance, leak tightness and long service life. ArmaWeld delivers welded fabrication for cylinder bodies, tanks and special manifold structures.
1. Hydraulic Cylinder Production
Critical weld details on a hydraulic cylinder body are at the head, base and flange regions. Typical materials include S355J2+N or 27MnCrB5. TIG root with MAG fill is common for full-penetration welds. Test pressure is generally 1.5× operating pressure.
2. Hydraulic Tanks and Reservoirs
The main goals for hydraulic tank fabrication are leak tightness and a smooth internal surface. Methods used to detect leaks:
- Air + soap-water test
- Helium leak test (high sensitivity)
- Vacuum test
- Penetrant testing (PT)
3. Manifolds and Special Blocks
| Part | Process | NDT |
|---|---|---|
| Cylinder body | TIG root + MAG | 100% VT, 10% UT |
| Tank shell | MAG (135) | 100% VT, leak test |
| Manifold | TIG (141) | 100% VT, pressure test |
| Pipeline | TIG root + MAG | 100% VT, RT/UT |
4. ArmaWeld Hydraulic Capability
ArmaWeld manufactures hydraulic tanks, cylinder bodies and manifold parts for construction and agricultural machinery OEMs. The production line includes certified welders, pressure test rigs up to 250 bar and surface coating infrastructure. Konya-based production gives a fast delivery advantage to customer plants across Türkiye.
