X-Rays and Gamma Rays-Their Industrial Application

1937-01-01
370138
THE X-ray spectrum readily adapts itself to problems in chemical analysis and crystal formation. It is effective on very minute particles which otherwise cannot be segregated. A permanent record is made, and the specimens may be used over and over again, as the X-ray is non-destructive. As a means of inspection, X-ray clearly shows the interior of objects such as weldings castings, forgings, cold-worked metals, and so on. Inhomogeneities that are very slight in width and a fraction of one per cent in thickness are seen easily on a radiograph. Defects thus found may be eliminated summarily by checking various steps in production.

Wheel and Brake (Sand and Permanent Mold) Castings - Minimum Requirements for Aircraft Applications

1965-01-20
HISTORICAL
AS586
This SAE Aerospace Standard (AS) sets forth the minimum quality required for aircraft wheel and brake castings. Its use will establish minimum acceptable requirements for internal structure and surface conditions and is predicated on the use of a casting factor for the ultimate load of more than 1.51 through 2.00. When casting factors of 1.25 through 1.50 are used, visual, penetrant, and radiographic or other approved equivalent nondestructive inspection methods shall all be required on each production casting. Where specific parts, or areas of parts, require a quality level exceeding that described by this document, the requirements shall be established by negotiation between the purchaser and vendor.

Weld Repair of Aircraft Quality Magnesium Castings

1957-01-01
570009
GENERAL techniques used in the weld repair of magnesium aircraft castings by both gas and arc welding methods are described here. Coverage is given to equipment, methods of surface preparation, preheating, welding procedure, post-heat-treatment. Some typical arc weld repair jobs are described and illustrated. Included also are descriptions of weld defects encountered because of poor welding technique. Typical mechanical property data are shown.
