Two-Axis Welding Positioners
8 two-axis (tilt-rotate) welding positioners, with rated load from 250 to 2000 kg across their variants. The two axes are rotation and tilt. The WB2LZ adds a lifting mechanism, and the WB2CH has an adjustable distance between headstock and tailstock.
Not sure which model fits?
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.
Two-axis welding positioners rotate and tilt the workpiece, bringing any seam on a three-dimensional part into the flat position. 8 models with rated loads from 250 to 2000 kg across their variants. The manufacturer describes its two-axis positioners as used in CRP robotic welding systems for stable weld quality and repeatable positioning.
Tilt is what a single-axis table cannot do: welded frames, brackets, gearbox housings and machinery bases have seams on several planes, and without tilt the robot must reach over the part at an angle that degrades both the weld and the reachable envelope.
The WB2CH adds an adjustable distance between headstock and tailstock, which suits a family of parts of different lengths on one fixture. Size by the part weight together with the fixture.
