Abstract:
A laser machining system includes a laser oscillator, a laser machining head, and a reflection unit. The laser oscillator outputs laser light. The laser machining head, which includes a first optical member for collecting the laser light, emits the collected laser light. The reflection unit, which includes a reflective member for reflecting the laser light emitted from the laser machining head, radiates the reflected laser light onto a work.
Abstract:
A fastening system (100) which comprises a welding stud (2) that is weldable to a carrier (1) and a disc (3) that is fastened to the welding stud (2) and has an opening (31) is specified. The welding stud (2) comprises a weld-on portion (21) for welding the welding stud (2) onto the carrier (1), a flange (22) and a pin-like portion (23) having an external thread (231). The disc (3) has an outside diameter (32) which is greater than a diameter (221) of the flange (22). The pin-like portion (23) has a thread-free region (235) which is arranged between the flange (22) and the external thread (231), and the disc (3) has latching means (33) which are configured for pushing the disc (3) over the external thread (231) and by means of which the disc (3) is latched in place in the thread-free region (235). Furthermore, a method for producing a fastening system (100) is specified.

Abstract:
This cladded aluminum-alloy material is provides with: an aluminum alloy core material, a coating material used to clad both surfaces of the core material; and a brazing material used to clad both of the coating material surfaces, or one of the coating material surfaces which is not at the core material side. The core material, the coating material and brazing filler material have described alloy compositions. The crystal grain size of the coating material before brazing heating is at least 60 µm. In a cross section of the core material in the rolling direction before brazing heating, when R1 (µm) represents the crystal grain size in the plate thickness direction, and R2 (µm) represents the crystal grain size in the rolling direction, R1/R2 is not more than 0.50. As a result, provided is a cladded aluminum-alloy material which exhibits excellent mouldability, and in which the coating material after brazing heating exhibits excellent corrosion resistance.
