Abstract: A laser welding apparatus includes a laser medium, an excitation light source and a control unit. The control unit supplies drive power to the excitation light source to inject excitation energy to the laser medium. The control unit supplies preliminary excitation power, which is smaller than pulsed drive power, to the excitation light source over a preliminary supply time, which is longer than a pulse width of the drive power before welding the first weld to be welded. After the preliminary supply time elapses and then an interval, the pulsed drive power is supplied to the excitation light source to weld the first weld.

Abstract: A positioning method positions a flexure whose front end side is joined to an outside frame with respect to a load beam, keeps the positioned state of the flexure and load beam, plastically deforms the outside frame to bead the front end side of the flexure so that the position of a tongue of the flexure is adjusted to the position of a dimple of the load beam, and joins the flexure and load beam to each other to keep the position adjusted state of the tongue.
