What is the purpose of surface preparation in inspections?

The purpose of surface preparation in inspections is critically focused on ensuring the effective adhesion of coatings and revealing surface defects. Proper surface preparation is essential because it creates a clean and suitable substrate for coatings, which can significantly affect performance and longevity. When a surface is adequately prepared, it minimizes contamination, such as oils, dirt, or oxidation, that could hinder the bonding process.

Additionally, this process allows inspectors to identify surface irregularities such as cracks, pitting, or corrosion that could compromise the integrity of the material or the overall structure. By exposing these defects, appropriate corrective measures can be taken before further work is completed. This emphasis on ensuring both adhesion and visibility of surface integrity is vital for maintaining the reliability and safety of equipment and structures in industrial settings.
