Tool for laser beam processing, laser beam processing apparatus and method for laser beam processing

A method for laser beam processing, the method comprising the acts of:

• fixing at least one component in a predefined position by way of an upper tool and a lower tool which are mutually converged by closing movement of a press;
• inducing thermal energy into the at least one component at at least one processing location by way of a laser beam for carrying out component processing, wherein
• the laser beam exits by way of a part of an internal face of the upper tool or of the lower tool that is designed as a laser beam exit face, and
• laser beam processing takes place in a temporal window in which the upper tool and the lower tool, by virtue of the closing movement of the press, in a manner of a protective housing shield environment from laser radiation;
• and
• providing an insertion unit by way of which at least one auxillary element is feedable by way of a feeding duct that leads through the upper or lower tool, wherein
• the feeding duct at the processing location opens into a tool interior on a side that is opposite the at least one laser beam exit face, and
• a feeding duct mouth is configured to position the at least one auxillary joining element precisely on the component.
