Large weld - Import export

The ultrasonic actuators of the TWINLINE product line are used for solving weld tasks with a Herrmann Ultrasonic 20 kHz twin sonotrode. The finely tuned twin-stack is mounted on a carriage. The construction and design principle allows for large weld forces and high precision. This product line also provides a number of variants.

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.

• 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.
