摘要： A hand-held laser welding wand includes internal flow passages through which filler media, gas, and coolant may flow. The wand is dimensioned to be grasped with a single hand, thus filler media of various types and forms, gas, and coolant may be supplied to the hand-held laser welding wand via external systems and delivery devices without substantially impairing operation of the wand.

摘要： A method for coating a surface of a turbine component with an environment-resistant and wear-resistant material includes the step of cold gas-dynamic spraying a powder material on the turbine component surface, the powder material comprising a mixture of MCrAlY powder and an abrasive powder such as cubic boron nitride, diamond, carbides, and oxides, with M being selected from Ni, Co and mixtures thereof. The method can further include the step of heat treating the turbine component after the cold gas-dynamic spraying. Thus, the present invention can be employed to greatly improve the performance and the durability of HPT components, and dramatically prolong their service life.

摘要： Methods are provided for repairing a worn surface of a steel die-cast die. The method includes heating an amorphous material to a predetermined temperature with a laser beam and allowing the melted amorphous material to solidify to thereby form an amorphous layer over the worn surface. These processes are useful for eliminating or minimizing cracking and/or part distortion and minimize heat-affected zone during welding. In addition, the formation of an amorphous layer over the worn surface allows the repaired die-cast die to better withstand typical operating environments than previous repair materials. These methods combine low heat input welding with amorphous alloys to effectively repair die-cast dies.
摘要翻译：提供了用于修复钢模压模的磨损表面的方法。该方法包括用激光束将非晶材料加热至预定温度，并使熔融的无定形材料固化，从而在磨损表面上形成非晶层。这些方法对于消除或最小化开裂和/或部件变形以及使焊接期间的热影响区域最小化是有用的。此外，在磨损表面上形成非晶层允许修复的压铸模具比以前的修补材料更好地承受典型的操作环境。这些方法结合了低热输入焊接和非晶态合金，有效地修复了压铸模具。

摘要： The present invention provides an apparatus for repairing turbine blades of a gas turbine engine by a laser welding operation. The method uses a miniaturized laser and related apparatus. The miniaturized laser is fed through a borescope access hole to a desired location such as a high pressure turbine blade. The laser is then powered and manipulated so as to perform the desired welding operation. Filler material may also be provided in situ to accomplish the welding procedure. The method realizes a significant cost savings to the vehicle operator in that repairs can be accomplished without the need to remove the engine or disassemble the engine.

摘要： A method is provided for repairing degraded and/or eroded areas on gas turbine blades and vanes. The method is directed to turbine blades and vanes made of advanced superalloy materials with high elevated-temperature properties. The method uses multiple laser beams to perform steps of preheating the repair area, welding the repair area, and post-welding heating of the repaired area. The method uses an array of two or more lasers to perform the steps of heating, welding, and post-weld heat treatment in nearly simultaneous operation thereby dramatically reducing or eliminating the hot cracking associated with other welding methods used with superalloy materials. The method is further directed to cladding or material buildup of degraded turbine blades where the weld material is the same as the matrix or better superalloy materials.

摘要： There is provided a method for depositing a modified MCrAlY coating on a turbine blade tip. The method utilizes laser deposition techniques to provide a metallurgical bond between a turbine blade substrate, such as a superalloy substrate, and the modified MCrAlY composition. Further the modified MCrAlY coating has sufficient thickness such that a post-welding grinding operation to size the turbine blade to a desired dimension will not remove the modified MCrAlY coating entirely. The modified MCrAlY coating thus remains on the finished turbine blade tip after grinding.
摘要翻译：提供了一种在涡轮叶片尖端上沉积改性MCrAlY涂层的方法。该方法利用激光沉积技术在涡轮叶片基底（例如超合金基底）和改性的MCrAlY组合物之间提供冶金结合。此外，改性的MCrAlY涂层具有足够的厚度，使得将涡轮叶片尺寸为所需尺寸的后焊研磨操作将不会完全除去改性的MCrAlY涂层。改进的MCrAlY涂层因此在研磨后保留在成品涡轮叶片尖端上。

摘要： A 3-D adaptive laser powder fusion welding system provides for both modeling/gauging of a workpiece as well as repair, restoration, and/or manufacture thereof. By providing a work platform and apparatus support system, five degrees of control in the form of two linear axes and three rotational axes are provided. The sixth linear axis is controlled via the displacement of a laser powder fusion (LPF) welding head and a laser rangefinding head. The laser rangefinding head system enables the workpiece W to be modeled electronically or otherwise. Additionally, the rangefinding system enables a model part to serve as a template from which repairs or construction are affected. The LPF welding head then affects any repairs or manufacture that are needed on the workpiece W. The LPF welding head is powered by filler material. The entire system is generally controlled by computer which enable the operator to be separated from a generally hot and hostile welding environment.
