NADCAP (National Aerospace and Defense Contractors Accreditation Program) includes a specific accreditation for the welding process. This accreditation program is designed to provide an independent assessment of the capabilities of suppliers who provide welding services to the aerospace and defense industries. The program is based on industry-developed and internationally recognized standards such as AWS (American Welding Society) D17.1, ASME (American Society of Mechanical Engineers) IX and ISO 9606. The objective of NADCAP welding accreditation is to ensure that suppliers consistently produce parts and materials that meet the required specifications and standards for the welding process. The program is intended to provide a level of quality assurance that goes beyond the traditional supplier surveillance and inspection methods.
