Laser Machining Cooling Holes In Gas Turbine Components
US Patent:
6420677, Jul 16, 2002
Filed:
Dec 20, 2000
Appl. No.:
09/741727
Inventors:
George Emer - Cresskill NJ
Frank Wos - Landing NJ
Dmitriy Romin - Brooklyn NY

Assignee:
Chromalloy Gas Turbine Corporation - Orangeburg NY
International Classification:
B23K 2600
US Classification:
21912171, 21912172, 21912167, 2191217, 21912168
Abstract:
The present invention provides a method of laser machining a cooling hole in a hollow gas turbine component, the cooling hole including a circular cross section metering hole and a diffuser with an opening which extends from a shape locus in the metering hole to a trapezoidal cross section opening by firing a series of laser pulses at an acute angle at the outer surface of the component toward the shape locus to create the diffuser opening, with the laser pulses penetrating the component outer surface up to but not substantially beyond the shape locus, then firing the laser through the shape locus and the inner surface of the component to create the metering hole having a circular cross section. Alternatively, the initial laser pulses are fired to create the central portion of the diffuser opening, then firing the laser to create the metering hole, followed by firing the laser along the peripheral portion of the diffuser opening.

Filed:
Jul 12, 2004
Appl. No.:
10/889207
Inventors:
Frank Wos - Landing NJ, US

Zengmei Wang Koenigsmann - Congers NY, US
Assignee:
Chromalloy Gas Turbine Corporation - Orangeburg NY
International Classification:
B23K026/20
US Classification:
21912164, 148524, 148525, 228231
Abstract:
A process is provided for crack-free welding a nickel based single crystal superalloy article containing at least 5 weight % total of Al and Ti. The process comprises: melting an article surface to be welded and a filler alloy with an energy source, preferably a laser, wherein the filler alloy is a composition of a nickel based single crystal superalloy except that the total of Al and Ti is reduced below 5 wt %; allowing the melted article surface and filler alloy to solidify to form a bead of deposit; providing a plurality of beads of adjacent deposits covering the article surface to be welded; and remelting the adjacent beads of deposits with the energy source to provide vertically oriented crystal growth in the deposits.
