Abstract: An object of the disclosure is to improve processing performance. Another object of the disclosure is to improve a working environment and reduce a failure of a processing apparatus. The processing apparatus includes a processing stage on which a composite material is set, a laser head that emits a laser beam in a predetermined direction to the composite material set on the processing stage, a blow off unit that blows off a shield gas to an irradiation point irradiated with the laser beam by the laser head, and an intake unit that takes in the shield gas blown from the blow off unit. The blow off unit and the intake unit are provided so as to interpose the irradiation point and face each other in a first intersecting direction and cause the shield gas to flow in one direction.

Abstract: An object is to improve the quality of a processed composite material without reducing the processing rate. A processing apparatus includes a laser head configured to irradiate a front face of a composite material with a laser beam and a gas supply unit configured to supply an assist gas to an irradiation point irradiated with the laser beam by the laser head. The gas supply unit has a first-level nozzle configured to eject the assist gas to an area at or near the irradiation point and a second nozzle configured to eject the assist gas to an area at or near the irradiation point and arranged above the first-level nozzle. The angle of the direction in which the first-level nozzle ejects the assist gas relative to the front face differs from the angle of the direction in which the second nozzle ejects the assist gas relative to the front face.

Abstract: The method for producing an assembly is a method for producing an assembly equipped with a member to be reinforced (20), a reinforcing member body (41), and a filler (42), wherein the reinforcing member body (41) has a pair of flanges (44) arranged spaced on the surface (20B) of the member to be reinforced (20), a web (45), and a connection portion (46) which connects the flanges (44) and the web (45) and forms a filler space (V) with the surface (20B). The method for producing an assembly includes a step for inserting a filler (42) into the filler space (V), a step for attaching a crack control member (43) to cover the end of the filler (42), a step for joining the flanges (44) and the member to be reinforced (20), and a step for curing at least the member to be reinforced (20).
