    • A method of repairing an aperture and adjacent defect in a part which is started by removing one or more defects adjacent an aperture in a base material. The material is removed to create a weld seam that extends past an area of high stress concentration on the aperture. An insert of material containing a profile that corresponds to the profile of the base material removed adjacent the aperture and a combination top and runoff plate that encompasses the insert of material are provided. A backing plate is inserted underneath the combination top and runoff plate and insert such that there remains an air space between the backing plate and the combination plate which prevents the combination plate from becoming fused to the backing plate during a welding process. The insert is welded to the base material, and the backing plate is removed. Excess material is removed from the insert to obtain an aperture containing a profile essentially the same as the profile of the aperture prior to initiating the repair.
    • 修复通过去除与基材中的孔相邻的一个或多个缺陷而开始的部分中的孔和相邻缺陷的方法。 去除材料以产生延伸超过孔径上的高应力集中区域的焊缝。 提供了一种包含对应于邻近孔径移除的基底材料轮廓的轮廓的材料插入物和包含材料插入物的组合顶部和径流板。 背板被插入到组合顶部和径流板之下并插入,使得在背板和组合板之间保留有空气空间,这防止了组合板在焊接过程中与衬板熔合。 将刀片焊接到基底材料上,并且去除背板。 从插入件中取出多余的材料,以获得一个孔,其中包含在开始修复之前基本上与孔的轮廓相同的轮廓。
