Abstract: The procedure for radiation support forming, remodeling, joining and separation of workpieces by mounted power transmission contact optics, comprises subjecting radiation energy into the workpiece over the contact optics with a transmission contact between the contact optics and the workpiece. The contact optics affects during the transmission of the radiation energy on the workpiece. Pressurized heat proof transparent materials serve as radiation energy source, laser energy source and/or transparent contact optics, which exists out of a material like diamond, sapphire and quartz glass. The procedure for radiation support forming, remodeling, joining and separation of workpieces by mounted power transmission contact optics, comprises subjecting radiation energy into the workpiece over the contact optics with a transmission contact between the contact optics and the workpiece. The contact optics affects during the transmission of the radiation energy on the workpiece. Pressurized heat proof transparent materials serve as radiation energy source, laser energy source and/or transparent contact optics, which exists out of a material like diamond, sapphire and quartz glass. During radiation support sintering of three-dimensional micro parts, sinter powder heats between the contact optics and matrices. The heat energy and pressure necessary for sintering are transmitted through the contact optics or matrices lying in flux through which the shaping of the micro parts is carried out over the integrated structure in the contact optics and the matrices. During the radiation support surface structuring, the workpiece is pressed in the surface of the other workpiece with geometrically determined or undetermined nano- and/or micro structures (quartz dust or corundum dust) integrated on the contact optics with certain grain size over the contact optics for remodeling the surface structure. The radiation energy is led over the contact optics into the surface of the workpiece during the pressing for warm working. The nano- and/or micro structure is removed after pressing. Large surfaces and/or certain areas of the surfaces are processed through transferring press tool on the workpiece surface. The pressing power is subjected over the contact optics on a micro press tool during the radiation support forming with press tool and the contact optics. The press tool is pushed over the contact optics in the workpiece so that the tool heats through the radiation energy during the pressing. The radiation energy is used during radiation welding with contact optics, during radiation support sintering on the surface of the metal body with contact optics and/or during the radiation support adhesion with the contact optics. The workpieces locally melt to produce a new material consistency. The production process is carried out with pressing power in contrast to the conventional contact less radiation welding. The welding of workpieces like a metal foil is carried out on a massive metal body with one another. The sinter material scattered on a surface of the massive metal body or a thin metallic body is used to sinter the workpiece surface. The workpiece, which forms a friction-fit connection with another workpiece is heated during the radiation support pressing. The contact optics enables a power on parts to be pasted and simultaneously shortens or enables local warming of the adhesion through the transmission of radiation. The contact optics controllably makes an exact positioning of the part to be pasted. During radiation support separation of non-positive connection with contact optics, the workpiece is heated over a transmittable radiation impacting through the contact optics. The workpiece expands through warming and the extension difference between the workpieces produces the separation power.
