Summary of Nondestructive Inspection Standards for Heavy Section Castings, Forgings, and Weldments

摘要

Code bodies, notably ASTM, have produced procedural guides, standard methods, and recommended practices which can be used to assure proper inspection for the various methods of nondestructive testing. These guides and practices in private industry have been reviewed for their applicability to quality control of heavy steel castings, forgings, and weldments. Acceptance criteria are not set forth, and recommendations are not suggested. They do, however, define levels of quality and describe the parameters generally agreed to be of significance which should be a part of the contractural agreement. The user must quantify these parameters according to service requirements and other considerations. (Author)
