NASA Tech Briefs are issued to summarize specific innovations derived from the U.S. space program, 
to encourage their commercial application. Copies are available to the public at 15 cents each

Tube Welding and Brazing 
Brochures have been prepared outlining the tools, 
equipment, materials, and techniques used by the 
George C. Marshall Space Flight Center for joining 
tubes by automatic and semiautomatic welding and 
brazing. Three methods are used in tube joining by 
welding; one method using a filler, and two methods 
not requiring filler wire. Induction brazing is being 
developed to provide high-quality joints, while a solid 
state induction brazing power supply is in the research 
and development stage. 
A few of the metals being joined by brazing or weld-
ing are Hastelloy C, 304L, 321, and 347 stainless 
steels of various diameters and wall thicknesses. Tech-
niques have been developed for on-site or work-bench 
repair.
