Nozzle Guide Vane Repair

Nozzle guide vane repair with Huffman Laser Powder Fusion Systems involves welding CF6-50 Nozzle Guide Vanes.

Process

• Engine repair parts.
• Laser powder fusion welding with vision system.
• Multi-axis capability combines operations and completes full part with one setup.
• Vision system locates the part, adjusts for differences and generates CNC program.
• Precise deposition of material minimizes post-weld processing.

Cycle Times

• Depends on weld configuration and quantity of weld.
• Typical time for this part is 40 minutes.

Machine Features and Benefits

• Available on the Huffman HP-115, HW-185 and HC-205 series laser machines.
• Laser powder fusion welding available on 3-, 4- or 5-axis configurations.
• Vision system is integrated with the CNC to accommodate incoming part variation and minimize manual operation.
• Precise, controlled deposition of filler material.
• Very low heat input means minimal distortion and metallurgical damage.
• Eliminates need to replace flanges.
• With a 5-axis machine, process can build up radial and axial surfaces to restore geometry.
