Weld levelling
The aim of levelling is to adjust the last weld layer applied to the height of the workpiece.
What does weld levelling mean?
The purpose of levelling is to adjust the last applied weld to the height of the workpiece. This means that protruding areas of the so-called top layer are ground off. The result is a seamless, even surface. This can be finished later with other tools, e.g. to create a high-gloss surface or a surface with a satin feel.
Levelling with grinding discs is difficult and requires some practice to hit the right angle. Otherwise, undesirable phenomena such as undercutting and gouging can occur.
The use of flap discs is much more convenient for this work step. They can be used in a more controlled and precise manner, have a long service life and are less noisy.
Which tools do I use for weld levelling?
Flap discs with zirconia alumina in a cambered shape are suitable for levelling. This shape has the advantage that the contact pressure can be applied precisely to a small contact surface. This means that the material can be removed precisely and cleanly only at the necessary points.
Depending on the desired grinding pattern of the top layer after levelling, grit sizes of 36-40 can be used for a coarse pattern. If a finer surface appearance is desired - e.g. because the surface will be polished or lacquered afterwards - a grit size of 60-80 should be used.

Products for
Weld levelling.
CERA PLUS
Superior
Flap disc with self-sharpening ceramic grain, which permanently enables an extremely high removal rate and guarantees a long service life. Outstanding results for surface and edge grinding of steel or stainless steel. The robust polyester backing and a full resin bond with additives that actively support grinding guarantee that the abrasive grain on the backing remains resistant to wear, even under high stress. This makes CERA PLUS ideal for extreme grinding work or demanding special tasks.
ALOX POWER
Perfect
Cost-effective product for processing steel and wood. A tough, hard abrasive grain enables good removal rates, particularly when grinding surfaces. The glass fibre backing is characterised by an even grinding finish until the abrasive grain is completely consumed. No scratches appear on the workpiece.
ZIRCON PRIME G-AZ
Superior
Special flap disc with zirconium corundum. This abrasive grain cloth is less hard, but very tough, and gives the disc very good all purpose characteristics.
