A method for welding balls provides a component, provides at least two balls, places at least one first ball of the at least two balls on the component, and applies an electrical voltage in such a manner that a current flows through the at least two balls and through the component, wherein the at least two balls are simultaneously welded together and the first ball is simultaneously welded to the component.

Method for welding balls

A method for welding components includes the following steps: providing a first component and a second component; bringing together the two components; welding the two components by use of a laser beam, wherein a plurality of welding impulses are generated through the repeated activation and deactivation of the laser beam, with each welding pulse being interrupted by welding-free rest intervals in which the laser beam is deactivated, wherein a local welding area is generated by each welding pulse, in which material of the two components is melted and fused in a locally limited manner, wherein individual welding areas of those generated by the welding pulses overlap.

Method for welding components

A method is provided for manufacturing a combination of components. The method includes the following steps: manufacturing a functional element by providing a plate-type base element and integrally bonding a ball or a ball-shaped element to the plate-type base element, in particular by welding a ball or a ball-shaped element onto a flat plate-type element, and joining the functional element to a first component.

A tool for laser beam processing is provided. The tool includes an upper tool and a lower tool, which are able to be advanced toward one another by way of a press, such that at least one component is able to be fixed in a predefined position between the upper tool and the lower tool. At least one laser beam exit surface, which is part of an inner surface of the upper tool or lower tool, and at least one laser beam guide, into which laser radiation is able to be coupled and is able to be directed through the laser beam exit surface onto a processing location on the component are provided. A control device, which enables and/or disables the coupling of laser radiation into the at least one laser beam guide depending on the advancing movement between upper tool and lower tool is provided. Furthermore, a laser beam processing apparatus and a method for laser beam processing are also provided.

A method for welding two components is provided. The method includes providing a first component, which has a convex elevation, and providing a second component, which has a through-hole. The method also includes placing the two components one against the other such that the convex elevation of the first component protrudes into the through-hole in an interlocking manner, and welding the two components along the rim of the through-hole by way of a laser welding device. The welding is performed without the use of a welding filler and the laser welding device is repeatedly switched on and off in a pulsed manner during the welding of the two components along the rim of the through-hole.

Method for welding two components

A component connection is provided, having a first component in which a first hole is provided, a second component in which a second hole is provided, and a connecting element which has two interconnected spheres or two interconnected spherical elements. Centers of the two spheres or spherical elements are located on a straight line which extends perpendicular to a first equatorial plane of the first sphere or of the first spherical element. Perpendicular to a second equatorial plane of the second sphere or the second spherical element, an edge of the first hole and an edge of the second hole both extend into an undercut area situated between the two equatorial planes such that an interlocking and/or frictional connection is produced in the undercut area. The connection resists pulling-apart forces acting on the two components.

A component connection has a first component, a second component with a through hole, and a connecting element, by which the two components are connected to each other. The connecting element has at least two balls connected to each other, of which a first ball extends, at least over part of the diameter thereof, through the through-hole. A second ball of the connecting element is pressed into the material of the first component such that the second ball is connected to the first component in a positive-locking manner.

A component connection includes a first component, which is made of a material attractable by a magnet, and a second component which lies directly or indirectly adjacent to the first component and which has a hole. A magnetic element is provided which covers the hole and attracts the first component such that both components are clamped together.
