Problems solved by technology

[0010] The disadvantage in this case is that in such a construction it is not possible to use a transverse jet guide, so that after a relatively short welding time the laser optics are contaminated by the welding spatter produced and the laser power is thus significantly reduced

Abstract

The invention relates to a device, especially a laser-hybrid welding head, for a laser-hybrid welding process. A laser or a laser optical system or an optical focussing unit and elements of a welding torch for an arc-welding process or of a supply device for a welding wire, and a device for forming a cross jet which is connected to a pressurised air supply system by at least one feed line and one discharge line are located on at least one mounting element. Said feed line and said discharge line for the pressurised air of the cross jet are located between the two components, especially the laser or the laser optical system or the optical focussing unit and the elements of the welding torch or the supply device for the welding wire.

Description

[0001] This application is a divisional application of the invention patent application with application number 01818956.3. The filing date of the original application was May 18, 2001, and the title of the invention was "A device for laser hybrid welding process". technical field [0002] The invention relates to a transverse jet guide for a laser hybrid welding process, as stated in claim 1 . Background technique [0003] Devices for laser hybrid welding processes, in particular laser hybrid welding heads, are known in which a laser or laser optics or an optical focusing device and a welding torch are arranged on at least one mounting plate. In this case, a transverse jet guide is assigned to the laser or the optical focusing device to form the transverse jet, which is connected via at least one inlet line and one outlet line to a compressed air supply. Due to the so-called transverse jet, the welding spatter generated during the welding process is kept away from the opti...
