The reliable detection and sizing of weld corrosion is not straightforward, because the region of greatest wall loss is usually underneath the weld cap, which prevents direct use of ultrasonic 0º compression wave techniques. Only rarely is it possible to remove the weld cap. In addition, the location and morphology of weld corrosion can be highly variable and unpredictable. There are often issues of access; these are due to the geometry changes associated with pipe welds, such as weld neck flanges, bends, valves and reducers, etc. In addition, misalignment and mismatch can affect the interpretation of results.

This Issue 2 of HOIS RP2 supersedes Issue 1, which was published in December 2009, and presents a unified recommended practice for the in-service inspection for weld corrosion in carbon steel components. It makes recommendations regarding the preferred inspection methods and techniques for a variety of conditions.

At present, this document is limited to the inspection for weld corrosion in carbon steel welds only.
