Cladding system ETR-S

Innovative and efficient: Endless Torch Rotation – System

In addition, the new ETR system complies with the features of the „conventional“ TIG Hot Wire Cladding System as regards weld quality, functionality and software features (e.g. „Bore-to-Bore“-Function).
At the core of the ETR Welding System is the so-called „transfer module“ that conducts all media required for welding (shielding gas, torch coolant) as well as the welding power and electrical signals through a rotary transmission leadthrough to the welding head. Thanks to its „co-rotating“ filler wire spool and wire feeder the ETR-S also ensures an optimum wire transport. Moreover the ETR-S features a long slide that bears the inside cladding torch. This slide is used for adjusting the required bore diameter (up to 300 mm), however, during welding it also performs the function of the Arc Voltage Control (AVC). The entire system is mounted on an FCS cross-slide which in turn is fastened on a FCB tripod unit.
