Description: 
The Institute has a continuing interest in metal joining. Areas of 
specific activity include spot, seam, butt, and gas-shielded welding, brazing, 
analysis of hydrogen in weld seams, and training programs for welders. 
Equipment for welding sintered aluminum powder (SAP) has been developed. 
The effort expended in metallurgical research is extensive. Heat- 
treatment studies have considered artificial aging, quenching, carburizing, 
nitriding, and handling of long bars in quenching. Machining is becoming 
a more important interest of the staff. Research in grinding and polishing 
turbine blades, broaching, high-speed cutting, and lubricants and cooling 
fluids is currently of interest. Devices for the rapid machining of gears 
and gages for lathes have been developed. Automation of foundries, machine 
shops, welding facilities, and chemical analysis is being studied. Alloy- 
development work includes research on hydrogen reduction in alloys, metal- 
lography, alloy additions, and mechanical-property testing and improvement. 
Polymers have been investigated for use in gears. Physical proper- 
ties of polymers also are of interest. 
Equipment for testing gyroscopes is being developed. Also research 
in compass transmitters and theory of gyro motion is under way. 
The Institute offers courses in casting of ferrous and nonferrous 
metals, thermal processing of metals (metallography, equipment, and 
technolcgy), metalworking (forging, stamping, rolling, and sheathing), 
welding, aircraft construction, aircraft engines and propulsion devices, 
aircraft equipment and instrumentation, and plastics. It grants Candidate's 
Degrees and frequently publishes a Trudy.
