A method for connecting two components with the aid of a laser weld seam. The two components are situated one above the other in a joining area. The first component is pressed in the direction of the second component with the aid of a clamping device. A laser beam impacts the first component on the side facing away from the second component and at least indirectly fusing material of the two components.

A shift in position of a laser beam used for welding objects is corrected without need for intervention by a welder. An irradiator performs welding along a welding part of objects to be welded by relatively moving objects to be welded and a nozzle for emitting a laser beam. An arm apparatus movably holds the nozzle while applying a biasing force to the nozzle in a direction toward the welding part such that the nozzle comes into contact with objects to be welded to irradiate the welding part with the laser beam.

A fusion welding device includes: a robot arm; a fusion welding hand attached to the robot arm and including a fusion welding head for fusing and joining together workpieces while being separated from the workpieces; a support provided to the fusion welding hand and abutting on the workpieces; a force sensor for detecting a force and a moment exerted, through the support, by the workpieces; and a control section configured to control motion of the robot arm in accordance with parameters calculated from a signal outputted from the force sensor.

It is an object of the present invention to provide a method of producing a vacuum thermal insulation panel capable of reducing the occurrence probability of poor welding of a metal outer wrapping material. The method of producing the vacuum thermal insulation panels 100, 100A to 100 D, 101, 101A according to the present invention includes a “covering step of covering a core material 110 or 110B with a metal foil 130 or 131” and a “welding step of welding a metal foil portion on an outer side of the core material”, and the core material is at least partially covered with a cover 120, 120A, or 120D at a timing when the covering step is to be started. Note that when the entire surface of the core material is covered with the cover, it is preferable to reduce the inside of the cover to seal the cover before the covering step, and when a part of the core material is covered with the cover, it is preferable to simultaneously reduce a pressure inside the metal foil and a pressure inside the cover to seal the metal foil.

A method for welding a plurality of wire segment pairs is disclosed. Each wire segment pair has two adjacent wire segments, and each adjacent wire segment has a contact region where the wire segment is to be welded to the respective other wire segment. The wire segment pairs are successively guided between two elements of a pressing unit, and at a weld moment in which at least one of the wire segment pairs is located between the two elements. The pressing unit exerts a pressing force onto the wire segment pair such that the contact regions of the wire segments are pressed against each other. At each weld moment, laser radiation is irradiated onto the wire segment pair to which the pressing unit is exerting the pressing force, and the laser radiation is irradiated onto a region in which the contact regions are pressed against each other.

A laser processing device for processing workpieces such as by welding includes a laser processing head and a workpiece clamping claw defining an opening through which the laser beam is focused on the workpiece. Each of the laser processing head and the clamping claw have respective shielding portions and movable relative to each other to selectively form a light-tight housing about a portion of the beam extending between the laser head and the clamping claw.

A laser welding machine includes: an elevator that is capable of sliding an elevating platform; a pressing actuator that is fixed to the elevating platform at a base part of the pressing actuator and has a tip slidably connected to the base part and pressing a conductive upper terminal toward a conductive lower terminal; a laser oscillator; a machining optical device that is fixed to the elevating platform and has a lens to focus the laser light emitted from the laser oscillator; a position detector that detects a vertical positioning of the pressing actuator; a counter that receives an output of the position detector and delivers position information; and a control circuit that controls, based on the received signal from the counter, the elevator, the pressing actuator, and the machining optical device, and controls operation of the laser oscillator.

An optical wheel assembly for a laser transmission welding apparatus includes a double-convex optical lens having two spherical surfaces that are joined by a polished side surface extending circumferentially around the lens. Each of the two spherical surfaces has a known spherical diameter. The optical lens is disposed between a pair of dish cup holders, each having a spherical concave surface with the known spherical diameter and engaging the spherical surfaces of the lens. Each dish cup holder has an axial projection extending away from a side of the dish cup holder that is opposite the spherical concave surface. The axial projections are received within respective bearings that are mounted within a housing. The bearings allow the dish cup holders and the optical lens to rotate while pressure is being applied to plastic workpieces during laser transmission welding thereof.
