Abstract: A method manufactures a head suspension by laser-welding the flexure to the load beam at a first welding spot so that a tongue is pressed against a convex portion under predetermined load. The method includes step of forming, before joining the flexure and load beam together, at least one positioning reference hole in each of the flexure and load beam within a circular range that is defined around the first welding spot with a radius equal to a distance between the first welding spot and the projection, laying the flexure and load beam one on another, inserting reference pin into the reference holes, and laser-welding the flexure and load beam to each other at the first welding spot.
Abstract translation: 一种方法通过在第一焊接点处将挠曲件激光焊接到负载梁来制造头部悬架，使得舌片在预定负载下被压靠在凸部上。 该方法包括在将挠曲和负载梁结合在一起之前形成在弯曲和负载梁的每一个中的圆周范围内的至少一个定位参考孔的步骤，其围绕第一焊接点限定，半径等于 第一焊点和投影，将挠曲和负载梁放在另一个上，将参考销插入到参考孔中，并在第一焊接点处将弯曲和负载梁激光焊接到彼此。

Abstract: A reference block which is machined from a single body of material and is a single block with reference pins integral therewith is configured for use in a method of manufacturing a head suspension by laser-welding the flexure to the load beam at a first welding spot so that a tongue is pressed against a convex portion under predetermined load. The method includes steps of forming, before joining the flexure and load beam together, at least one positioning reference hole in each of the flexure and load beam within a circular range that is defined around the first welding spot with a radius equal to a distance between the first welding spot and the projection, laying the flexure and load beam one on another, inserting the reference pins of the reference pin block into the reference holes, and laser-welding the flexure and load beam to each other at the first welding spot.
Abstract translation: 由单个材料体加工而成的具有与其成一体的基准销的单个块的参考块被构造成用于通过在第一焊接点处将挠曲件激光焊接到负载梁来制造磁头悬架的方法，从而 在预定负荷下将舌头压在凸部上。 该方法包括以下步骤：在将挠曲和负载梁结合在一起之前形成在每个弯曲和负载梁内的至少一个定位参考孔，该圆弧范围围绕第一焊接点限定，半径等于 第一焊接点和投影板，将挠曲和负载梁放置在另一个上，将参考销块的参考销插入到参考孔中，并且在第一焊接点处将挠曲和负载梁激光焊接到彼此。

Abstract: As first-time laser irradiation is performed on a workpiece, an initial nugget is formed. By emitting a laser beam for the second time at the initial nugget, a diameter of a back-side nugget portion is increased. A nugget includes a front-side nugget portion formed in a first plate, the back-side nugget portion formed in a second plate, and an annular flat surface portion. The flat surface portion is along a boundary portion between the first plate and the second plate. In a thicknesswise cross section of the second plate, a tilt angle of a peripheral surface of the back-side nugget portion is increased as a thicknesswise position of the peripheral surface approximates to a rear face of the second plate.
