摘要： The present invention has as its object to provide a laser welded joint excellent in joint strength preventing a bead from cracking and comprised of exactly the number of weld beads required for joint strength and a laser welding method for the same in overlay laser welding of steel sheets forming multiple ring-shaped weld beads. The present invention is a laser welded joint excellent in joint strength preventing a bead from cracking and comprised of exactly the number of weld beads required for joint strength in overlay laser welding of steel sheets forming multiple ring-shaped weld beads, produced by a step of overlaying a plurality of metal sheets and forming a first weld bead and a step of firing a laser beam to successively form a further two or more weld beads at the outside of the first weld bead by laser irradiation, the surface hardness of the weld bead increasing from the inside bead to the outside bead.

摘要： A containment plenum (240) is adapted to deliver laser light to an interaction region of an inhabitable structure to remove material from the structure. The containment plenum (240) includes a plenum housing (242) adapted to be coupled to a source of laser light. The containment plenum (240) further includes a window (243) substantially transparent to the laser light. The window (243) is mounted within the plenum housing (242) to transmit the laser light in a downstream direction and to provide a barrier to upstream transport of particulate matter generated by interaction of the laser light and the structure. The containment plenum (240) further includes a nozzle (244) fluidly coupled to a source of compressed gas. The nozzle (244) is mounted downstream of the window (243) whereby the laser light and the compressed gas are transmitted through the nozzle (244) in the downstream direction to the interaction region of the structure. The containment plenum (240) further includes a resilient interface (246) coupled to the plenum housing (242) and adapted to resiliently contact the structure and to substantially surround the interaction region, thereby confining the material and removing the material from the interaction region.

摘要： La présente invention concerne un dispositif formant tête optique pour diriger un faisceau laser sur la surface à traiter d'une paroi d'une pièce, telle qu'un cylindre de moteur à combustion interne.
Le dispositif est caractérisé en ce que le miroir plan (2) de réflexion du faisceau laser est fixé au corps (3) de la tête optique de façon à diriger le faisceau laser sur la surface à traiter (S) suivant un angle d'attaque incliné par rapport à un plan perpendiculaire à la paroi (1a) de la pièce (1) et à l'axe longitudinal du corps (3) pour éviter le retour du faisceau laser sur le miroir (2).
L'invention trouve application dans l'usinage de précision de cylindres de moteurs à combustion interne.

摘要： A focusing head (1) of a laser beam (2) provided with a focusing lens (7; 57) for a machine for working parts comprises an extractable lens-holding frame (6) that supports the focusing lens (7; 57), a supporting and centering bracket (20) wherein the lens-holding frame (6) is mounted in a disengageable manner, a spring (26) in engagement with the supporting and centering bracket (20) to urge the lens-holding frame (6) in abutment against a stop socket (30). In that way the lens-holding frame (6) is disengageable from the supporting and centering bracket (20) by an action of compression of the spring (26) and it can be extracted and reassembled in said focusing head (1) without modifying centering and positioning of the focal spot of said lens (7; 57).
