Single-Axis Welding Positioners
15 models: single-axis welding positioners and the WD linear track, with rated load from 150 to 5000 kg across their variants. The positioners have one axis of rotation and come without a tailstock, with an idle or a movable tailstock, with roller supports, as vertical tables with or without tilt, and as lift-and-rotate units. The WD linear track has one linear axis.

Send the part weight, the reach you need and the cycle. We will name the model — and say plainly if a robot is not the right answer for it.
Single-axis welding positioners rotate the workpiece about one axis. 15 models, including the WD linear track, with rated loads from 150 to 5000 kg across their variants: versions without a tailstock, with a movable or idle tailstock, with roller supports, vertical tables with or without tilt, lift-and-rotate units, and the WD linear track for moving the robot itself. For the single-axis positioners with a tailstock, with roller supports, of the vertical type and the WB1LC, the manufacturer states accurate rotation and stable fixation of the part for consistent weld quality.
One rotation axis is enough for anything cylindrical or symmetrical: pipe spools, flanges, wheels, shafts, drums and pressure vessel shells. The robot welds a stationary seam while the part turns underneath it.
The WB1KH and WB1KHT variants add a movable tailstock for parts of varying length; the WB1LG series uses roller supports for large-diameter thin-wall vessels that would deform on a chuck. The WD linear track carries the robot along the workpiece rather than turning it — the choice when a part is too long or heavy to rotate.
