PROBLEM TO BE SOLVED: To provide a soldering laser head equipped with a mechanism which can prevent dust such as flux slag generated during soldering from adhering to an optical component such as an optical lens.SOLUTION: In a soldering laser head 1 that performs soldering by projecting a laser beam B to a soldering object 3 to melt solder 5 supplied to the soldering object 3, a housing 2 with a built-in optical component is provided with an air nozzle 21 and a dust tray 22 that constitute an air curtain mechanism 7 so as to face each other with an optical axis L of the laser beam B therebetween, where the air nozzle 21 has an air injection port 25 extending slenderly in a direction orthogonal to the optical axis L and is arranged so as to inject air in a direction crossing the optical axis L from the air injection port 25 toward the dust tray 22, and the dust tray 22 has an air inflow port 34 to receive the air from the air nozzle 21 and filters 38a, 38b, 38c that capture dust flowing with the air into the air inflow port 34. |
