  • Exceptional cooling to ensure the best possible welding results

    Fronius has developed a modified TIG process: ArcTig. The process for mechanised joint welding allows high welding speed as well as high seam quality. Users can weld up to ten-millimetre-thick, high-alloy sheets and pipes without extensive seam preparation, to an exceptionally high quality standard and much quicker.

    The key innovation is the optimised welding torch with an electrode clamping system, which enables the electrode to be cooled right to the tip. This increases the combined resistance and creates a high arc voltage. Electron emission now takes place over a small area but at an extremely high density. This makes the arc narrower and more targeted. Another advantage of the cooling is that it prevents overheating of the electrode during welding, providing increased arc stability and ensuring a longer service life and improved ignition. Users can upgrade all TIG power sources from Fronius above an output of 220 amperes to the ArcTig process with ease. The ArcTig welding process is designed for applications in container and pipeline construction, in the manufacture of turbines and the construction of special machines, cranes and tanks.

    Shorter processing times and lower filler metal costs

    The focussed and high-pressure arc means the ArcTig can be used to weld components in one layer to a material thickness of up to ten millimetres. Additionally, it is frequently the case that users no longer need to do time-consuming preparation work on parts. As there is no gap during seam preparation, no weld pool support is required for the ArcTig process. This cuts down on rework to a large extent, since the weld seam is raised to a minimal degree and there is very little distortion due to the reduced heat input. This enables users to accelerate processing times considerably, while the welding process also permits higher welding speeds. What's more, material costs are lowered as the weld seam volume is reduced. The ArcTig process also impresses in terms of operation: because it is very similar to TIG welding, users do not have to adjust to a new process and can weld immediately without carrying out any time-consuming teaching-in.
