Turbine Overhaul (OH) Test 1 Practice

Blade blending focuses on restoring the blade’s surface and aerodynamic profile after fabrication or repair, and the steps you’d expect to see are documenting the work, inspecting for damage, and cleaning and blending the blade surface to remove irregularities. Documentation ensures traceability of what was done, inspection catches cracks or wear early, and cleaning and blending smooths the surface to prevent stress concentrations and maintain proper aerodynamics. Balancing after manufacturing is a separate procedure aimed at ensuring the rotor’s overall dynamic balance by adjusting mass across blades or the wheel assembly. It occurs after blade fabrication and during final assembly or overhaul, not as part of the blade surface blending work. So balancing after manufacturing is not part of the blade blending process.
