TIG welding with intelligent control that adapts to the operator

in its automatic self-regulation. The welding system actively adjusts the wire speed to the welding behaviour, torch position and current conditions, even automatically compensating for component tolerances of up to 30 per cent. During development of the cold-wire system, Fronius examined the process in detail to ensure that welders could work optimally with minimal steps and adjustments. The wirefeeder is set once and then remains in a stable position. The ergonomic and flexible tungsten holder is particularly lightweight as it is produced using material-saving aluminium 3D printing. There are also no vibrations at the torch handle, as the mechanical forward and backward motion of the wire has been dispensed with entirely with the new TIG DynamicWire cold-wire welding process. With the Tungsten fast clamp system, Fronius is bringing out another new patent. A single touch of the button releases and clamps the tungsten electrode in the spring-loaded clamping sleeve. Like the lead of a mechanical pencil, the electrode is changed in a matter of seconds. This system can now also be mounted on existing torch bodies. In times of skills shortages, iWave complete with cold-wirefeeding

TIG COLD-WIRE components are now available for Fronius iWave, which features an intelligent control. With the patented new TIG DynamicWire welding package, even amateurs can achieve good quality TIG welds. This is because the dynamic wire control always selects the right travel speed. The process adapts to the welder, rather than the other way around. Historically, TIG welding has represented the top tier of welding processes and demands skill as well as years of practice. “All the new features that we’ve packed into the iWave cold-wire components, as well as the corresponding software solution, make TIG welding significantly easier,” said Manuel Rumpl, head of strategic product management industrial welding solutions at Fronius International GmbH. “Thanks to TIG DynamicWire, welders can focus all their attention on the arc and the welding system regulates the optimal wire speed at all times.” The iWave power categories from 300i to 500i can be upgraded to the TIG cold-wire system. The TIG DynamicWire welding package is ready for use immediately by means of software activation and can also be retrofitted to existing iWave systems. The advantage of Fronius DynamicWire compared to a conventional continuous wire feed lies

and TIG DynamicWire, can help all TIG novices – and those with less experience – achieve a great welding result. Self-regulating parameter settings and characteristics, as well as a compensatory active wirefeeder, provide the necessary safety and ensure a high level of quality. Since the wire does not continuously move back and forth during intelligent TIG cold-wire welding, even wear parts such as the torch body, torch cap, and clamping sleeve experience reduced abrasion and last longer than comparable solutions. iWave can help all TIG novices and those with less experience achieve a great welding result

Flexible diameter gauge heads from Sikora AG THE LASER Series 2000/6000 includes various laser-based gauge heads that continuously measure contactless diameter and ovality during extrusion. The advantages of the devices are their precision and production-proven design. The optical components are located in protected areas so that process-related dust and dirt particles do not affect the measurement. In addition, the diffraction analysis, in which the diameter is deter- mined from the diffraction fringe, detects unavoidable, gradually The larger gauge heads, which cover a product diameter from 30mm, as well as all 3-axis gauge heads are designed open at the bottom so that neither water nor dirt can enter the gauge head.

A special feature is the swiveling measuring head concept, which allows the measuring head to be easily moved out of the working area. The measuring heads are free of wear parts, retain their precision throughout the entire operating life and require no calibration or maintenance.
