Particular challenges To correct the effect of the tolerances of the parts, the welding robots path in conventional applications is usually adjusted, by means of a time consuming manual correction (teaching). The warping effect caused by the thermal expansion however cannot be compensated this way. For this purpose, QuellTech offers a perfectly tailored seam tracking solution, which is based on a QuellTech 2D-Laserline Sensor of the Q4 family. The method consists in measurement of the real position and width immediately ahead of the welding process. The laser sensor captures the real dimension of the weld bead, and the software used for this process simultaneously sends the nominal position to the robot. The robot performs a correction movement in X or Z position according to this measurement. This way not only the deviation caused by tolerances, but also the warping effect can be compensated – and the weldment takes place exactly at the required position.

With high demands on accuracy and dynamics, the base frame in welded construction or hard stone is also a possible and reasonable part of the scope of supply. Here, all axes are specified, assembled, aligned, measured, tested and recorded - according to desired specifications. By means of hard stone, the required accuracies can be achieved. Hard stone offers all the characteristics required - ranging from a small coefficient of expansion, high abrasion resistance, optimum vibration damping, absence of unwanted residual stresses up to the necessary accuracies regarding flatness, parallelisms and angularity.

Our patented desuperheater TECtemp HT R ring cooler is designed with a three-part structure without moving parts and without weld seams in the steam lances. These are arranged in a ring shape depending on the steam pipe nominal diameter. For example. 40 individually controlled nozzles can be used in this way. Homogeneous distribution of the injection water makes short evaporation sections and minimal load of the steam pipe possible. The geometry of the steam lances acts like a venturi nozzle in the steam pipe which results in clearly reduced loss of pressure.

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, ...), …

Optimal machine design for 20 kHz applications for which the joining process must be precisely performed by several sonotrodes in a single weld process. The rigid sonotrode support is realized by means of individual alignment modules and allows for accurate positioning even at large weld forces. Contrary to conventional designs, the weld stroke is performed by the anvil. During this stage, the plastic parts to be welded are moved against the stationary sonotrodes. Thus, it is possible to obtain machine cycle times of less than 10 seconds.

Shuttle table machines are characterized by an operating area that is separated from the loading station. The plastic parts to be welded can thus be optimally loaded into the equipment. Thanks to good accessibility, assembly and loading tasks can be easily performed. Can optionally be designed with one or more work stations. Approach of several operating positions is performed by means of a freely programmable linear drive. In this way, weld tasks can be divided into individual process steps. Tool change systems: optionally available.

With the help of the MULTICELL concept, small multi-head applications can be easily implemented. In general, the plastic parts to be welded are loaded directly below the sonotrodes. A shuttle table can be optionally integrated for improved handling. This modular concept is particularly suitable for 20 kHz applications with sound insulation and can be customized by installation of a large number of accessory options. The compact make-up and high degree of mobility allow for universal application in manufacturing.

The core of this ultrasonic welding machine is the patented pneumatic HMC drive concept. It combines the benefits of pneumatics with the dynamics of an electrical drive and allows for selection of any optional start point for the weld process. The SoftTouch mode protects the sensitive joining area of the plastic parts to be welded during contact of the sonotrode.

Suitable also for welding precision mechanical parts and medical technology components as well as for the manufacture of sensors and electrical components The ALS 100 is an ergonomic workplace The spacious work chamber offers a very brightly lit work area and is loaded via two side doors. The average power of 100 W enables a fast pulse sequence (up to 25 Hz) and thus fast work even at high energy settings. The homogeneous fusion of the materials results in welding results of the highest quality. The laser is used in the manufacture and repair of jewelry, in precision engineering or when welding sensors

The desktop laser welding machine delivers with 50 watts good beam power and is characterized by its uniform, powerful, yet soft welding behaviour. The manual welding laser VL 50 has a very spacious working chamber and allows to weld precious metals such as silver and gold due to its powerful laser behaviour. Longer concentrated work is easily possible thanks to the ergonomically designed housing with the well thought-out arrangement of keyboard, display and joystick. The desktop laser VL 50 is a valued tool in the manufacture and repair of dentures and jewelry, in welding on precision parts, medical technology components and sensors, but also when applying materials to small molds.

The LVW series covers smaller applications with machines of approx. 500 mm width and large applications up to a width of 2000 mm, like pallets, bumpers and more. As a principle our standard machines are equipped with an hydraulic lifting table. Depending on the machine size a contact force of up to 70 kN can be applied. This is necessary for large suction pipes made of PA 6.6 GV30 with heavy distortion or very large welding surfaces. Our vibration welders are fitted with our patented CPC system. This kind of regulation which is integrated in the converter stimulates the vibration unit with optimal resonance frequency. A low energy consumption is guaranteed during the friction phase. It is not necessary to enter the frequency parameter in the machine, as it is permanently “optimized”. This, the KLN drive systems are independent from the tool weight. The tool weight is solely limited in height, caused by the mechanical design and the high accelerating powers arising in these systems.

For the assembly of plastic parts, which differ in size and condition and would therefore not be suitable for standard machines, we recommend the use of special equipment with several ultrasonic units for ultrasonic welding and processing methods. • Riveting • Welding • spot welding • punching • flanging • cutting • embossing • printing Multi-head systems These machines can also be used to accomplish complex tasks, e.g. the combination of different welding techniques, like spin welding and hotplate welding and for numerous automated processes
