 |
|
| Surface Eddy current and ACFM are both electromagnetic methods for detecting surface breaking cracks, both lend themselves to easy deployment with industrial rope access. Though fundamentally different both techniques use equipment that is lightweight and portable, with the capability to have a probe operated remotely if needed.
|
|
|
|
| Both surface eddy current testing and ACFM can have advantages over liquid penetrant or magnetic particle testing in certain applications: |
|
- Testing can be significantly more sensitive in the detection of tight cracks (for example, stress corrosion cracks in stainless steels)
- Testing can measure crack depth in non-ferromagnetic materials, whereas magnetic particle testing does not have this capability.
- Surface eddy current testing and ACFM can detect surface cracks in the base material through some coatings.
- In small areas, testing can be much faster; liquid penetrant testing may be slow because of the long dwell times.
- Less surface preparation may be required, which can be an advantage in difficult access areas and harsh environments such as legs or risers on offshore vessels.

|
| Using industrial rope access to deploy these techniques greatly reduces costs by allowing access to difficult areas without the need for scaffolding or other support structures. |
