Apparatus for laser twist weld of compressor blisks airfoils |
摘要 |
Apparatus for performing laser weld repair of complex titanium-base material parts for gas turbine engines. The complex arts, typically compressor blisk airfoil assemblies are enclosed in a local dry box and purged in an inert gas atmosphere. Laser weld repairs are accomplished within this dry box by using a coaxial nozzle and a mixture of helium and argon. The welding is accomplished by maintaining a proper standoff between the weld nozzle and the weld. The welding is monitored and controlled from a remote location using in a video camera system. Copper shielding is provided within the dry box to protect areas adjacent to the weld area from overheating and weld spatter.
