Abstract: A work piece includes a weld. A management device includes a camera, a control unit, and a database. Information on the work piece and a product ID are linked to each other and stored in the database. The weld of the work piece is captured and a nugget pattern thereof is subjected to image processing to obtain pattern data. The pattern data is linked to the product ID and stored in the database. A weld of a work piece with an unknown product ID is captured and a nugget pattern is subjected to image processing to obtain check data. This check data is checked against the existing pattern data, and when the matching data and the existing pattern data match, the product ID linked to the existing pattern data is acquired.

Abstract: According to an embodiment, a manufacturing method of a disk drive suspension comprises determining a first position on the outrigger at which a bent portion is to be formed by irradiating a first laser beam, calculating predicted values of pitch and roll angles of a tongue in a case where the bent portion is formed at the first position, determining a second position on the outrigger to which a second laser beam is to be irradiated to make the predicted values approximate to predetermined target values, and irradiating the first laser beam to the first position to form the bent portion, and the second laser beam to the second position.
