Abstract: A device is provided for processing hard-to-access workpieces by means of an imaging optical path as well as a corresponding method for laser processing by means of this device, comprising a relay optical system with an optical axis passing through the relay optical system and a focusing unit arranged behind the same seen in the optical axis in the propagation direction of the imaging optical path, with a plurality of optical elements for generating a third focal length, as well as a beam scanner arranged before the first relay optical group seen in the propagation direction of the imaging optical path, which scanner is provided both as an entrance pupil for the imaging optical path entering the first relay optical group and at least for deflecting the imaging optical path in relation to the optical axis.

Abstract: A laser beam irradiation apparatus including a laser source configured to emit light; a collimator configured to collimate the emitted light; a scanner configured to adjust the collimated light to change an irradiation direction thereof; a first lens part configured to focus the adjusted light to irradiate a laser beam on a sealing part; a camera configured to receive visible light passing through the scanner; a heat sensing part configured to receive infrared (IR) light passing through the scanner; and a control part configured to control a moving direction and an intensity of the laser beam.

Abstract: A method is disclosed for joining two components (1, 2), a first component (I) and a second component (2), in the region of a joint zone by means of at least one laser beam. In a first phase, the first component (I) is melted, and a melt lens is formed in the first component (I) from the molten material (9). In a second phase, at least one pressure pulse is applied to the melt in the direction of the second component (2) until the melt lens is deflected into the joint gap as a result of the pressure pulse, bridges the joint gap, and comes into contact with the second component (2), and energy is transmitted to the second component (2) as a result of the melt lens coming into contact with the second component. A temperature curve results in the second component (2) as a result of the energy transmission such that the melting temperature is reached on the upper face of the second component (2), and a melt film is formed.

Abstract: A method of producing a welding seam with a single laser pulse, the laser pulse and the work piece being moved relative to each other at a high velocity. This results in the length of the welding seam formed being primarily the product of pulse duration of the laser pulse and the relative velocity of work piece and laser pulse. The invention also relates to a method in which the work piece moved at high velocity relative to the laser beam is subjected along the welding seam to be formed to repeated applications of a single laser pulse. In that case the length of the welding seam is defined principally of the product of pulse duration of the laser pulse and the relative velocity of the work piece and laser pulse divided by the number of applications.
