5. NOTES
5.1 Intended use. This handbook is intended to outline the methods for non-destructive inspection to insure that joints welded in accordance with the processes of this handbook will meet the inspection guidelines of section 4.2.
5.2 Post machining. Welded joints inspected in-process prior to machining of the weld, should require visual and fluorescent pentrant or magnetic particle inspection after machining operations.
5.3 Physical limitations. When part configuration or size make magnetic particle inspection impractical, the weld joint may be inspected by fluorescent penetrant method providing approval has been given in writing by the responsible acquisition agency.
5.4 Straightening. Parts distorted as a result of excessive overall or localized heat input during welding, may be straightened provided they are not in the heat treated condition. Parts should be fluorescent penetrant or magnetic particle inspected for cracks after the straightening operation.
5.5 Subject term (key word) listing.
