Abstract: A joined body includes: a thin plate including through holes; a first member including a proximal portion having a portion contacting the thin plate, and a protruding portion that protrudes in relation to a contact surface of the proximal portion and is inserted through the through hole; and a second member arranged oppositely to the proximal portion via the thin plate and made of a material that is same as that of the first member. The thin plate is made of a material having a specific gravity smaller than that of the material forming the first and the second members. The second member and an end portion of the protruding portion are connected to each other, by a part of the second member and a part of the end portion being melt-solidified, the end portion being at a side opposite to a side connected to the proximal portion.

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.
