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.

The QuellTech 2D-Laserline Sensor is specially prepared to the highly disturbing ambient light from the weld process. 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.

Discover our highly effective mobile welding protection wall made of cardboard - the perfect solution to protect your working environment from flying sparks and fire hazards during welding and grinding. This cut-to-size cardboard combines welding protection with environmental protection.

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.

Schnelldorfer CORNERWELD seam welding machines have been designed to weld sheet metal plates in a 90° joint. The precision clamping system with inert gas coverage and advanced OEM control package precisely controls the welding sequence and weld parameters, resulting in the perfect weld for your corners. CORNERWELD applications include welded corners for food, medical equipment, HVAC drip pans, electrical enclosures, and laboratory furniture. Complex inward and outward flanges can be accommodated with custom made tooling pieces. A wide range of materials can be welded, including Stainless Steel, Carbon Steel and Aluminium. Complete welded parts do not require any costly grinding, polishing or blending thus greatly saving on manufacturing costs.

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.

• TIG welding: The letters TIG stand for tungsten inert gas welding and generally belong to the inert gas welding process. In this welding process, an arc burns between a tungsten electrode (non-consumable) and the workpiece. The electrode, the arc and the molten bath are protected from the atmosphere by an inert gas. • MIG / MAG welding: The letters MIG stand for metal inert gas, the letters MAG for metal active gas. This welding process is also part of the group of metal inert gas welding processes. In this welding process, a consumable wire electrode is fed continuously. The arc burns between the supplied wire and the workpiece. Throughout the welding process, the arc and the weld pool are protected by either an active gas (MAG process) or an inert gas (MIG process). This welding process can be used for a variety of materials and is also available for a large number of welding consumables.
