摘要

The device for laser-welding of a cylindrical body (1) on a planar plate (2), where an adjustable welding head (3) is arranged in axial direction of the cylindrical body to a laser head (4, 5), and the welding head is parallely adjusted to the plane of the planar plate in an angle to the axial direction of the cylindrical body, comprises a first sensor (7) by which the position of the cylindrical body is ascertainable and/or a first welding head drive by which the welding head is adjusted in an angle for the axial direction of the cylindrical body. The device for laser-welding of a cylindrical body (1) on a planar plate (2), where an adjustable welding head (3) is arranged in axial direction of the cylindrical body to a laser head (4, 5), and the welding head is parallely adjusted to the plane of the planar plate in an angle to the axial direction of the cylindrical body, comprises a first sensor (7) by which the position of the cylindrical body is ascertainable and/or a first welding head drive by which the welding head is adjusted in an angle for the axial direction of the cylindrical body. The welding head is adjusted towards the surface normal of the planar plate, and a spacer by which the spacing of the welding head is limited to the planar plate at a minimum value, where the spacer is arranged towards the surface normal of the planar plate adjustable in the welding head. The device comprises a guiding element, which has a recess by which the cylindrical body is partially covered. The laser head is arranged towards or in an angle to the surface normal of the plate adjustable at the welding head, and is pivotably arranged on a radius around the welding head. The midpoint of the radius lies on the tangent of the cylindrical body with the planar plate. The device comprises a second sensor by which the position of the guiding element is relatively ascertainable to the welding head.
