pre-NDT paint removal
pre-NDT paint removal
(OP)
I have a painted metal part, recently removed from service, that requires liquid penetrant inspection. I am aware that the paint must be removed, and that the method cannot "smear" the surface such that indications would be covered over by displaced metal. thus abrasive blasting, etc. is not acceptable. based on previous experience, i am wary of solvents that might damage the surface of the part. is it acceptable to pressure wash the part (not using any sort of abrasive in the water, just high pressure?)





RE: pre-NDT paint removal
What is the material specification? What type of component are you talking about (service conditions)? What type of paint?
Regards,
RLS

the materials are cast nickel aluminum bronze and titanium. the surfaces are machined. the paint is epoxy, and was applied with minimal surface preparation. so i don't think it will be that difficult to remove.
