Glass bead blasting
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.

The alloy metals react chemically with the oxygen in the air, forming a thin layer that protects the iron from corrosion. When stainless steel is processed, the protective surface layer is penetrated. This is seen as dark tarnishing around welded seams, cutting edges, and burnt grinding dust. The pickling process is used to remove harmful discoloration – both the oxides and the underlying de-chromed layer. After this, the protective layer can be restored.

Some items are too large to transport to the pickling center, making it impractical or impossible. Such items can be pickled using a mobile facility.
Large items that cannot be immersed in tanks can be treated through spray pickling.
To achieve a clean, uniform, and durable surface, it is essential to remove all impurities – especially tarnishes at welding seams and cutting edges – and to re-establish the oxide layer.
