Low force friction welding, a hybrid technology developed by EWI and MTI, uses an external energy source to raise the interface temperature of the parts being welded, reducing process forces required to make a solid-state weld compared to traditional friction welding. Low Force Friction Welding of Bimetallics: Aluminum 6061 to 1020 Steel Tubes, written by...

Ceramic matrix composite (CMC) materials offer great advantages in manufacturing including increased crack resistance, elongation, and thermal shock resistance. Joining CMCs to other materials, however, can be a difficult process involving multiple steps. EWI has developed a one-step brazing method for joining CMC material to itself, metals, and other ceramics. This new technique is described...

With rapid growth in the space exploration industry, there is great demand for fuel efficient, lightweight vehicles with increased capacity for payload. Advances in production materials offer several viable options for space manufacturers. Next Generation Materials for Space Launch Vehicles, a paper by EWI Applications Engineer Mike Eff, examines the material needs of today’s LVs...
