Removing welds on round aluminium
Traditional flap discs grind continuously, without interruption. On aluminium, they therefore clog quickly. Our interrupted abrasive flaps with surface conditioning technology ensure the disc constantly renews itself.

How to remove a weld on a round aluminium workpiece in 3 steps
Choose your flap disc
Choose the RCD that suits your weld: RCD/UC for heavy welds, RCD/CO or RCD/ME for standard weld seams. The FAC is the affordable choice.
Follow the curve
Work with light pressure and follow the curve of the tube. Keep moving, so you don’t create flat spots.
Check and finish
Check that the weld is flush with the surface everywhere. Want an even structure? Then finish with the RCD/VF.
Frequently asked questions about removing a weld on round aluminium
How do you remove a weld seam on a round aluminium tube?
Use a flap disc. The flaps adapt to the curve, so you remove the weld without creating flat spots. Follow the curve of the tube, keep moving and work with light pressure.
Why does a regular flap disc clog quickly on aluminium?
A traditional flap disc grinds continuously, without interruption. As a result, the aluminium quickly smears into the disc. The RCD has interrupted abrasive flaps and surface conditioning technology, so the disc constantly renews itself.
Which RCD flap disc do you choose for aluminium?
With the RCD, you grind away the weld and finish it in one step. Choose the RCD/UC for heavy welds, the RCD/CO or RCD/ME for standard weld seams and the RCD/VF to structure the surface.
Is there a more affordable flap disc for aluminium?
Yes, the FAC is a conical flap disc with zirconia grain, specially developed for aluminium. A coating prevents the disc from clogging. It is a good choice when a high-quality finish is not needed.
