For sanding hardened, alloyed and stainless steel.
For weld bead removal.
To make weld distribution as efficient and symmetrical as possible and use the least amount of material as possible.
Inoxidizable alloys are applied in the pharmaceutical, food and nuclear industries. That is why high quality is of utmost importance so the resulting work does not affect corrosion resistance or health of the surface.
Both the edges and the worked surfaces must be free of surface oxides and care must be taken from moisture, the presence of which can produce porosities in the weld bead, hence the importance of prior sanding and to ensure adequate finishes.
