THE engineering laboratory of the American Ryan Aeronautical Co. operates on two broad paths: analytical control and research. It controls the standards for all materials and processes used in manufacturing. Incoming stocks of metals such as corrosion‐resistant steels, aluminium alloys and magnesium must be carefully analysed to see that they are chemically correct and modified by heat‐treating and other processes to meet their specialised use in aircraft applications. All processes such as welding, plating, pickling, anodising, heat‐treating and degreasing are developed by the laboratory and remain under the surveillance of laboratory technicians.
