welding-alloys.com 11 3D-scan model of a Kaplan turbine blade. Advanced 3D scanning captures precise blade geometry, allowing accurate assessment of wear, distortion and profile deviation. This digital data improves repair planning, ensures correct surface restoration and supports quality control before and after machining or repair/hardfacing. Machining on site. On-site machining restores critical surfaces and dimensions after welding or hardfacing operations. This ensures correct clearances, smooth finishes and proper alignment of components, enabling reliable operation without costly dismantling or transport. Wire arc spray coating on a wicket gate Wire arc spray deposits a uniform, wear-resistant layer on wicket gate surfaces exposed to metal-tometal friction and corrosion. The coating rebuilds worn areas, improves sealing and offers a cost-effective, low-heat process suitable for large components. Pelton turbine bucket hardfacing. Welding restoration of turbines to increase resistance to erosion from high-velocity water jets. The protective deposit ensures durability, stable performance and extended service intervals under severe operating conditions. Wear-resistant liners for penstocks. Wear-resistant linings are applied to penstocks to protect against abrasion and particle-laden flow. These linings reduce material loss, stabilise internal surfaces and help maintain long-term efficiency by limiting hydraulic roughness and preventing premature failures. HVOF coating on turbine drive shaft HVOF thermal spraying produces a dense, highly adhesive coating that protects turbine drive shafts from abrasion, corrosion and fretting. The resulting surface delivers excellent hardness, low porosity and long-term reliability in high-load, high-moisture environments. Back to contents page
