To provide an airfoil that allows quick welding and minimizes the weld depth and width and the heat input.SOLUTION: An airfoil includes: an airfoil body; a recessed portion of a first depth in a first side of the airfoil body, the recessed portion including a plurality of pockets of a second depth located within the recessed portion and ribs of the first depth located between the pockets; a cover configured to fit into the recessed portion such that an interior surface of the cover engages the ribs and an exterior surface of the cover is about flush with an exterior surface of the first side of the airfoil body; and a high energy beam weld configuration extending through the cover into the ribs and positioned to attach the cover to the ribs.SELECTED DRAWING: Figure 1

    【課題】迅速に溶接可能であり、溶接部の深さ及び幅ならびに熱入力が最小限に抑えられるエアフォイルを提供する。【解決手段】エアフォイルであって、エアフォイル本体と、エアフォイル本体の第1の側部における第1の深さを有する窪み部分であって、窪み部分が、窪み部分内に位置する、第2の深さを有する複数のポケット、及びポケット間に位置する、第1の深さを有するリブ、を含む窪み部分と、カバーであって、カバーの内面がリブに係合し、カバーの外面がエアフォイル本体の第1の側部の外面とほぼ面一になるように、窪み部分に嵌るように構成されている、カバーと、カバーを貫いてリブ内へ延在し、カバーをリブに取り付けるように配置された高エネルギービーム溶接構造体と、を含む、エアフォイル。【選択図】図1
