Yes, work experience in the Power industry. For pressure vessels, piping, boiler and steam turbine components we require grit blast cleaning to remove surface oxides in preparation for wet fluorescent magnetic particle testing (WFMT). Vacuum blasting is also effective to minimize the ingress of grit into primary and secondary water/steam systems at Power Plants.
We have also looked at other forms of surface preparation like wire wheeling and jitter bugging. However, neither of these methods proved effective in removing heavy surface oxides in preparation for wet fluorescent MT.
