Welding
Pinpoint positioning

Modern robotic welding lines work quickly and with absolute precision. Positioners and rotary tables assure the exact alignment of workpieces. A gear provides the drive of the horizontal rotary axis for the rotary welding tables. In this manner, all welding points lying on this axis – even complicated geometric structures – can be welded with pinpoint precision in the tenth of a millimetre range without having to unclamp and reclamp the workpiece. In the process, the weld pool must always be held exactly in the pan.

This is only possible if the gear works with absolute precision and reliability. That way, even the slightest deviations and thus faulty welding points can be avoided. The sturdy and ultra-precise Nabtesco gears of the series RV-C, RV-E, RS-A and RD-C are especially well suited for such welding applications: They are compact, can absorb heavy impact loads and are distinguished by their low backlash. In addition, cables and supply lines can be tidily routed through the hollow shaft of the RV-C and RD-C gears.
