摘要： A laser cladding head (12) comprises a protective housing (18), a focal array (26), a turning mirror (36), and a powder nozzle (34). The housing (18) extends along a primary axis (A P ) from a proximal end (20) to a distal end (22). The focal array (26) is situated at the proximal end (20) and oriented to receive and focus collimated light (28) in a beam (28) directed substantially along the primary axis (Ap). The turning mirror (30) is situated at the distal end (22) and disposed to redirect the beam (28) in an emission direction, towards a target point (P T ) separated from the turning mirror (30) by a working distance (D T ) of at most a tenth the focal length. The turning mirror (30) is a nonfocal reflective surface indexable to alter an impingement location (P I ) of the beam (28) on the turning mirror (30). The powder nozzle (34) is situated at the distal end (22) and receives and directs weld material towards the target point (P T ) for melting.

摘要： A dual-wire hybrid welding system (10) includes a hybrid welding apparatus (20) having laser, electric arc welder (40) and second wire feeding device (50). Electric arc welder (40) includes first wire feeding device (42) for feeding first wire (44). Second wire feeding device (50) is arranged and disposed to feed a second wire (52) to electric arc welder (40). Laser (30) and electric arc welder (40) are arranged and disposed to direct energy toward at least two adjacent components (70) along a joint and first wire (44) is a consumable electrode fed into joint to establish molten pool generated by both laser (30) and arc welder (40) with first wire (44). Second wire (52) is fed to molten pool to form a common molten pool (60). Common molten pool (60) is operable to provide a full penetration weld (92) with less total heat input to join the at least two adjacent components (70) without cracking the components (70) at a high constant weld speed.

摘要： The present application relates to a laser processing equipment, in particular for welding, which uses a containment device (10) mounted to a laser head (18), a pressure sensor (58), a differential pressure generator and a controller. The containment device (10) has an outer shell (12) and an inner wall (42) defining a peripheral chamber (44) there in-between. Two seals (50, 52), mounted to the outer shell (12) and to the inner wall (42), are adapted to contact a workpiece (32). The peripheral chamber (44), encircling an opening in the laser containment device (10) for letting a laser beam reach a workpiece (32), is connected to the differential pressure generator. The pressure sensor (58) detects a differential pressure generated by the differential pressure generator within the peripheral chamber (44). In use, the laser head (18) emits its laser beam (30). The pressure sensor (58) sends its pressure readings to the controller which compares their values with a predetermined pressure threshold. If the pressure readings cross this threshold, the controller stops the emission of the laser beam (30).

摘要： The invention relates to a laser-machining device comprising an arrangement for producing and guiding a working laser beam and comprising a nozzle (2) having an opening for emission of the working laser beam to a machining zone. An optical axis (14) is defined in the arrangement and there is at least one element which focuses the working laser beam, such as a cutting lens, near the opening of the nozzle (2). The machining process is monitored by a suitable arrangement. Said monitoring occurs via at least one group of detector arrangements for radiation characteristic of the machining process and an associated evaluating unit, wherein the detector arrangements of each group are arranged in a ring shape about the optical axis (14). The observation direction of the detector arrangements extends, at least in a sub-region, between the focusing element closest to the machining zone and the machining zone, at a polar angle Phil of greater than 5°, in relation to the optical axis (14) of the working laser beam (3). Said device is preferably used as a laser cutting device.

The lower head portion has an outer housing, which is movably fixed through the upper head portion of the working arm attached to be movable. The releasable clamping device has an annular piston, which is an axial annular space of the laser cutting head of a housing and the head laterally movable element of a core in a basic position-fixing, the fixing of the head laterally movable element of a central part solving second position and back, is movable. The annular piston such as pneumatic is actuated in a sense of release, and on the one hand by a clamping surface with the laterally movable head element of the core, on the other hand with an acting for the purposes of fixing clamping unit is connected. The clamping surface is formed as a lower surface of an inner flange of the annular piston and the other clamping surface as an upper surface of an outer flange of the central part. The outer flange of the central part and/or the inner flange of the annular piston consists of segments that are arranged along a circumference spaced with a respective distance. The clamping unit of the releasable clamping device consists of a spring unit from three axial spring assembly. The laser processing machine is stored with the nozzle receiving in the lower head portion relatively movable head element of the core with a radial clearance whose value is 1-5 mm. The head element of the core and the coaxially movable nozzle receiving device are formed as a single integrated element. The laser processing machine is equipped with a work table to hold the workpiece to be machined. A camera system is provided in the adjusting station below the recording unit for fixing the nozzle, and is provided with a target for carrying shooting by the laser beam, a removable absorption plate and a height-adjustable camera. The camera of an image processing unit is assigned for detecting the relative position of penetration holes and/or detecting and comparing the surface extension of the penetration holes.
