摘要： 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.

摘要： A nozzle cleaning apparatus has one cleaning liquid outlet to which a nozzle is attached, and the other cleaning liquid outlet to which a cleaning attachment is attached. The cleaning attachment includes a nozzle cover, and a cleaning holder attached to the nozzle cover. A cleaning chamber is formed in the nozzle cover. A cleaning liquid inflow chamber, an outer cleaning liquid ejection port, and a cleaning liquid discharge hole are formed in the cleaning holder. A cleaning liquid ejected in a first direction from the nozzle and a cleaning liquid ejected in a second direction from the outer cleaning liquid ejection portion toward the nozzle collide with each other near discharge portions inside the cleaning chamber.

摘要： 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.
