Laser welding is a very gentle welding technique, as the heat input takes place in a locally very limited area. In this way, it is possible to reliably connect critical components with one another in a materially bonded manner, without the parts annealing. With laser welding, the two welding partners are joined together with as few gaps as possible in order to then weld them together (e.g. press-fit zones such as EloPin® puzzled at any feed or distance). The background to this is that no additional material is generally used in laser welding. Exception for build-up welding or repair welding of e.g. broken tool parts such as punches or cutting plates or injection molding tools for abrasive plastics with glass fiber filling. Materials - almost all metals: e.g. • non-ferrous metals (Cu, CuSn0.15, CuSn6, CuNiSi, ...), • titanium, • steel, stainless steel (1.4301, 1.4404, ...), • spring steel (1.4310), • electrical steel (M235, M270, NO20, NO30, ...), …

Adaptive optics is a special form of high-performance laser mirrors. Their characteristic is that the mirror surface is designed as a membrane, which can be deformed in a controlled manner by pressure change on its back. The shape errors occurring in this case are extremely low; we tolerate them with a maximum of 0.0005 mm. Our adaptive optics are suitable for use with laser power up to 10 KW thanks to integrated direct water cooling and HR coating. Most common types are the adaptive optics with elliptical membrane as these can be used directly to the 90 ° deflection. They are identical to our standard planes of identical aperture and therefore do not need special housings. In addition to the elliptical varieties, LT Ultra also offers round adaptive mirrors. As a rule, these replace the concave spherical mirror of an existing telescopic beam expander directly at the resonator. Round adaptive mirrors can only be used with deflections <10 °. …

RSLD is our short cut for a laser head consisting of a total of 3 motorized axes for use in large-format laser machines in gantry design for the 3-dimensional laser cutting of components. The horizontal main axis of the laser head permits endless movement, even during the rotary movement the axes below are permanently supplied with cooling water, process gases and all electrical signals. Suitable optics are used for the laser source used, either directly water-cooled metal mirrors with low-absorption coating or alternatively glass optics. The use of an adaptive optics enables the freely programmable focus position for cutting and piercing. The exclusive use of torque motors reduces mechanically moving components and thus guarantees consistently high machining accuracy and best machining results over a long service life, against mechanical damage reliably protects our proven 3D collision protection.

RSD is our short name for a laser head consisting of a total of 2 motorized axes for use in large-format laser machines in gantry design for 3-dimensional laser cutting / laser welding of components. The horizontal main axis of the laser head permits endless movement, even during the rotary movement the axes below are permanently supplied with cooling water, process gases and all electrical signals. Suitable optics are used for the laser source used, either directly water-cooled metal mirrors with coatings of least absorption, or alternatively glass optics. The use of an adaptive optics optionally allows the freely programmable focus position for cutting and piercing. The exclusive use of torque motors reduces mechanically moving components and thus guarantees consistently high machining accuracy and best machining results over a long service life, against mechanical damage reliably protects our proven 3D collision protection.

SD is our short cut for a laser head consisting of either the swivel axis only or in combination with a highly dynamic linear axis for laser processing of pipes. Suitable optics are used for the laser source used, either directly water-cooled metal mirrors with coatings of least absorption, or alternatively glass optics. The use of an adaptive optics optionally allows the freely programmable focus position for cutting and piercing. The exclusive use of torque motors reduces mechanically moving components and thus guarantees consistently high machining accuracy and best machining results over a long service life, against mechanical damage reliably protects our proven 3D collision protection. The clear aperture of the current laser swivel head SH35 is 35mm, the larger version SH60 is still available with a clear aperture of 60mm.

When using high-performance CO2 lasers for welding applications, metal mirrors are usually preferred for beam guidance. Depending on the desired application, the configuration of the machining head is composed of modular individual components according to customer requirements. The possibilities are almost unlimited, ranging from the simplest welding head to complex 3D machining heads. The FH40/C focusing heads are used for laser power up to 5 KW and raw beam diameters up to max. 30mm, the FH60 focusing head for laser power up to 15 KW and raw beam diameters up to max. 50mm. All optical units have connections for direct water cooling, are available with different coatings and are generally available from stock. In addition to the cross-jet for the efficient reduction of splashes and smell on the mirror optics, protective gas feeds with a lateral or coaxial flow direction are also offered for targeted coverage of the welding torch.

The laser cutting head FC4 is predominantly used in medium power lasers machines, impresses with its slim design and the related low weight. The use of a deformable (adaptive) mirror is of great importance in this case, since no motorized lens adjustment for focus adjustment is required any more. The focus adjustment via adaptive optics above the focusing lens is fast, reliable and precise. Focus positions for a wide variety of materials can be determined, stored in the machine CNC and called up for controlling the optics as desired. The dynamics of the adaptive optics are also clear when piercing the material before the beginning of the cut – for a full stroke, only 0.2 seconds are required. Especially when cutting thicker materials, the time saving can be considerable. The use of aspheric lenses guarantees the best optical properties; protective glass cassettes on both the collimation side and the pressure seal below the focusing lens protect the optics from contamination.

The laser cutting head FC1 is predominantly used in low to medium power lasers machines, impresses with its slim design and the related low weight. The use of aspheric lenses guarantees the best optical properties; protective glass cassettes on both the collimation side and the pressure seal below the focusing lens protect the optics from contamination. The technical design of the manual adjustment of the focus position is convincing by precision, the focus position can be precisely adjusted without tools via the generously dimensioned adjustment range of 20mm and can safely hold it without countering. The fast distance sensor allows precise control even when cutting the thinnest materials. Thus the FC1 offers excellent cutting performance at an interesting price.

When it comes to laser marking, the following types of marking are essentially differentiated: • temper colour: in the case of stainless steels and titanium, oxygen storage in the surface, • white engraving, • deep engraving, • Color removal e.g. of anodized layers for aluminum, • Color change of plastics (usually additives required in the plastic), • foaming of plastics, • ... The advantages of laser marking are on the one hand: • longevity, • Biocompatible for and in medical technology. In addition, laser inscription is: • individually designed, • space-saving thanks to data matrix code, • consecutive numbering can be generated (serial number, date of manufacture, ...), • cheap, as e.g. there are no mask costs compared to pad printing.

Laser cutting or laser fine cutting of metal, we can precisely process all metallic, non-toxic materials in material thicknesses from 0.2 to 2.0 mm. With our high-precision 1kW fiber laser (Nd: YAG with a wavelength of 1064nm) in combination with highly dynamic linear drives, we can produce your laser cuts in copper and brass. Due to our extremely small focus of 0.05mm, we usually create a cutting cag/ clearance of 0.07mm, so that the most delicate contours (especially inner contours) can be realized without mechanical stress, as the processing takes place without contact. This enables high-quality and precise prototypes and small series in contract manufacturing using cutting lasers. Accuracies of +/- 0.01mm, which are required in the sealing area for plastic overmolding for complete plugs or housings. Dimensions: sheet thicknesses from 0.2 to 2.0mm, max. sheet metal of max. 1,250mm x 1,250mm.
