The basic approach to the inspection and repair procedure for welding has barely altered for three decades. The normal practice has continued to be to inspect a weld only after the welding programme is complete.

Corrosion under insulation (CUI) is a real threat to the onstream reliability of many of today's plants.

The failures are often the result of localized corrosion and not general wasting over a large area. These failures can be catastrophic in nature, or at least, have an adverse economic effect in terms of downtime and repairs.
