Pickling Degree Determination
Determining the pickling grade is a visual or measuring inspection of residual impurities and scale freedom on a pickled metal surface. It ensures process quality is high enough before further processing.
Physicochemical mechanism of action
Determining the pickling grade refers to checking a metal surface after pickling. This is done visually or with special measuring devices to check residual impurities and scale freedom.
Metallurgical relevance & risks in welding
Inadequate pickling grade determination can lead to impurities that appear as defects during further processing or in the final product. This can cause production disruptions and extra costs.
Shop practice & action instructions
For correct pickling grade determination, follow these steps:
1. Carefully dry the metal surface after pickling.
2. Use either a visual inspection or special measuring devices to check the surface.
3. Compare the results with specified standards and quality criteria.
