20130081269, Apr 4, 2013

Filed:

Sep 30, 2011

Appl. No.:

13/249440

Inventors:

Timothy Joseph Trapp - Wyoming OH, US
Seth Carl Shira - Cardington OH, US
Jeffrey James Root - Columbus OH, US

International Classification:

B23P 6/00
B22D 31/00

US Classification:

29888, 29 33 A

Abstract:

A system for repairing holes in a turbine engine component is provided. The system includes a turbine engine component including a front surface, a back surface, and a tapered surface extending from the front surface to the back surface, the tapered surface circumscribing the hole. The system further includes a plug configured to be welded to the turbine engine component, the plug including at least one tapered portion configured to contact the tapered surface when the plug is welded to the turbine engine component, and a die plate positioned on the back surface of the turbine engine component and including an aperture defined therethrough that is configured to collect flash generated when the plug is welded to the turbine engine component.

US Classification:

432 9, 219221

Abstract:

A method of thermal management includes positioning a first workpiece and a second workpiece in at least one tool having internal cavities, passing a fluid into at least one of the internal cavities to cool portions of the first and second workpieces, welding the first workpiece and the second workpiece in the at least one tool by resistance heating to form a joined workpiece, controlling a rate of cooling of the joined workpiece to slow a rate of cooling through at least one of a resistive heat element or welding electrode of the at least one tool. A localized thermal management tool includes a mounting block, a first heater block having a first workpiece engagement surface, a second heater block having a second workpiece engagement surface, a resistive heater mounted within at least one of the first heater block and the second heater block, a first cooling clamp engaging the mounting block and the first heater block, a second cooling clamp engaging the mounting block and the second heater block, a cooling fluid conduit disposed in at least one of the first and second cooling clamps, an insulator between each of the heater blocks and the cooling clamps.
