If one wishes to perform glass bead blasting on welded joints, it is necessary to pickle the material beforehand to remove both discolorations and the dechromed layer.
It is not possible to blast away discolorations without pickling or grinding, as this would not remove the dechromed layer beneath the discolorations, which would greatly reduce the corrosion resistance of the material.
High-quality glass beads do not contaminate the material and do not contain any toxic substances. The beads are chemically inert and are therefore not harmful to health.
At KD Bejds, we only perform glass bead blasting on stainless steel materials to avoid rust particles in our glass.
