Friction Processes (Page 5)

Improving the service life of welded structures is a key goal in the energy, transportation, heavy manufacturing, and defense industries. Decreasing or delaying fatigue crack initiation can add years of service and reduce costs significantly for an ongoing operation. EWI recently conducted an early-stage feasibility study to assess friction surface processing, a new technique for...

EWI and MTI, developers of the new joining methodology low force friction welding, have continued a series of materials studies over the past year to qualify the new process for a variety of metals. A new paper by EWI Senior Technology Leader Jerry Gould, Application of Low Force Friction Welding to a 6061-T6 Aluminum Alloy,...

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...
