Dear All,
according to ASTM G48 Method A (Pitting corrosion test), we are suppose to polish all surfaces of the specimen to a uniform finish until a minimum of A120-grit. Does this applies to test specimens which have welding? If yes, then are we not testing the original surface condition of the test specimen, specifically the weld cap and weld root?
