Welding - Import export

High quality, productive longitudinal seam welding calls for the utilisation of advanced, superior technology. This enables us to us to protect and expand our market position despite increasingly fierce competition. Our ELENA® longitudinal seam welders provide unsurpassed technology for welding of longitudinal metallic seams.

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.

It can be cooled and protected from weld spatter, so this model proves to be particularly adequate for operation in the harsh environment of the welding process.

ROTAWELD is our platform to cover a wide range of applications requiring circumferential seam welding. The precision servomotor rotation axis combined with our advanced control system form the basis for the production of accurate and repeatable circumferential seam welds. Machine sizes, part holders, welding equipment, torch holders and any additional positional axes are designed specific to the customer and their products.

thicknessGAUGE C.LL sensor systems use laser triangulation sensors for the thickness measurement. These laser sensors enable high measuring rates at high speeds. The thicknessGAUGE.laser series impresses with a favorable price/performance ratio and is preferably used for thickness measurements of common surfaces such as plastics, wood and metals.

Side-seam bags are used for transportation and protection of light contents. Solid welding seams and easy confectioning turn the side-seam bags into an economically priced all-round solution. We look forward to your inquiry by mail or by phone: +49 (0)9181/2960-0!

The ALFlak systems offer you many options in the field of mobile laser and repair welding. With an extended range and increased travel range, welding positions in deep, complex shapes can be processed easily thanks to the long laser arm - even in deep, bulky shapes. Deposition welding with wire or powder is possible with this laser machine. Likewise, automated welding tasks. The laser device is equipped with a fiber source that guarantees high efficiency and a special beam quality. Both pulsed and CW mode can be used. The integrated performance monitoring ensures reproducible welds. This system is available with laser powers of 300/450/600 and 900 watts.

AL-SWS - the multifunctional laser workstation with variable table inserts for sensor production With this flexible laser machine you can effortlessly weld and cut even the smallest workpieces up to 12 mm in diameter, either automatically or manually. This laser system is mainly used in sensor production and in medical technology, for example for the production of jacket-insulated cables, sensors, resistance thermometers and thermocouples. Depending on the desired application, five different, interchangeable table inserts are available. These can be changed in a matter of seconds so that you can easily switch between the following welding or cutting tasks: Contact welding Circular welding Micro welding To cut Mantle welding under mechanical pressure

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.

You won’t get it more flexible. The mobile welding laser AL-ARM was developed to quickly and flexibly repair offset seams, pores and penetrations in the car body. The fiber laser system can be positioned quickly and has a long range. The 3D visualization with integrated laser safety glasses enables the user to observe his welding task as well as the surroundings. The welding process is shown enlarged and the process-relevant data is also visible in the image. The handpiece, which is used for welding, is equipped with an automated wire feed and an integrated shielding gas nozzle. It weighs just 1.5 kg and is easy to position. There is no set-up time for welding.

This laser system is quickly set up for the welding task. The flexible laser arm can be rotated 360 ° and offers a very high or low working position. The laser head can be rotated to the left and right and the tilt-swivel lens directs the laser beam to the point desired by the operator. The robust housing has stable aluminum handles at the corners for increased impact protection of the edges. Integrated fastening options are available here for easy lashing during transport. The gas bottle can be transported during welding with a small trailer, the 5th wheel on the laser. Generous storage areas and special brackets on the machine sides ensure that tools, welding wire and whatever else is always within reach. Operation is intuitive via a touch display. Some apps help to weld surfaces, shafts and circular welds. The 450 W fiber laser can be used for pulsed welding or for welding in CW mode.

The ALW is a comfortable, ergonomic, and compact seated workstation that offers plenty of legroom, and which can be adjusted to the height of the operator via the height-adjustable foot plate. The observation lens offers a variable viewing angle from 10° – 50°, thus ensuring comfortable working. The closed, laser-proof housing makes the ALW a laser-protected workplace that can be used in a normal production environment without additional safety precautions. The laser system is easy to operate. In addition to configuring via the display, the laser parameters can be adjusted via the patented multifunction footswitch or adapted accordingly during welding. The large doors of the ALW can be opened wide. This facilitates easy loading.

Compacted material terminals made from Cu-ETP1 and Cu-OF1, in bare and tin-plated, nickel-plated and silver-plated upon request, in hard or soft annealed. Cross-section ranging from 1 mm² to 95 mm² depending on welding area. Compact welded terminals of different copper strands can be automated processed. A production of individual parts is possible as well as large-scale production. Resistance welded strands by LEONI are particularly suitable for high-voltage battery connectors, for high power connectors, for switch contacts and for special applications.
