摘要： A superalloy substrate, such as a turbine blade or vane, is fabricated or repaired by laser beam welding to clad one or more layers on the substrate. Laser optical energy is transferred to the welding filler material and underlying substrate to assure filler melting and adequate substrate surface wetting for good fusion. Energy transfer is maintained below a level that jeopardizes substrate thermal degradation. Optical energy transfer to the filler and substrate is maintained uniformly as the laser beam and substrate are moved relative to each other along a translation path by varying the energy transfer rate to compensate for localized substrate topology variations.
摘要翻译：通过激光束焊接来制造或修复超级合金基底，例如涡轮机叶片或叶片，以在基底上包覆一个或多个层。激光光学能量被转移到焊接填充材料和下面的基底上以确保填充物熔化并且适当的基底表面润湿以实现良好的熔合。能量传输保持在低于基材热降解水平的水平以下。当激光束和衬底沿着平移路径相对于彼此移动时，通过改变能量传输速率来补偿局部衬底拓扑变化，向填充物和衬底的光能传输保持均匀。

摘要： An apparatus (10) and method for evaluating an effect of a surface presentation angle (A). The apparatus supports a plurality of samples (12) separated by support plates (18) between end plates (22) in a shish kebab arrangement. A groove (34) is formed on each side of each support plate for receiving an edge of each respective sample at a different angle relative to an axis of impingement (32). A clamping mechanism (20) holds the end plates, support plates and samples together in the fixed orientation exposing each sample surface at a different presentation angle, yet at the same distance from a process end effector (30). The sample impingement surfaces are exposed to the process, and the effect of the different surface presentation angles is determined from the samples. Process variables to counter the effects of surface presentation angle may be identified and controlled.

摘要： A damaged portion of a superalloy material turbine blade body is removed, forming an excavated recess. A repair splice is formed of a same material with similar mechanical structural properties, having a mating outer profile conforming to the corresponding recess profile. The repair splice is inserted and captured within the recess, so that the blade body and repair splice are mechanically interlocked. Given similarities in mechanical properties of both the blade body and the mechanically interlocked splice the repaired blade's overall mechanical structural properties are similar to those of an undamaged blade. The repair splice is affixed to the blade body so that the interlocking respective portions of each do not separate. Localized affixation and subsequent cosmetic blade surface repair can be performed with softer, low temperature application braze and weld alloys
