Acceptance criteria for surface ECT

Hi
Is there any criteria for surface ECT for acceptance and rejection.

Surface ECT with absolute probe technique on Inconnel625 meterial.

Jagan,
no.
Eddy current notche standard for flat surface (including surface round), bolt hole, but also pipes, are established for the production or in the service. For example AF specification, ASTM E 426, when matched with product specification, especially those of the main manufacturers of aircraft and avio turbine, where inconel,nickel alloys and titanium, are widely used. RR, MTU, Snecma, P & W, etc., have elaborated in detail their specifications to detect crack-like surface signals. Of course the scope is well defined.
Do not understand what you're handling. I suggest you retrieve and comply with the specifications of the product manufacturer to prevent improper application. Remains in your 'scope'.
greetings
mario

BS EN 1711 outlines that any indication found to be verified by MPI/ LPT,
Criteria will wary depending on what stage is the product like Mill , finishing(weld), in-service(SCC, fatigue) and applicable industry( Aero, nuclear,O&G)

Generally all liner indications are to be repaired.

NAT,

BS EN 1711 is to perform surface inspection on the welds.

...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
