Technical Program – Day 3
Wednesday, April 29, 2009

Exhibit Hours: None
Refreshment Break: 9:45 – 10:00 am

Session Description: New processes in brazing, soldering, and diffusion welding of aluminum, titanium and magnesium alloys will be presented in this Session. Use of TLP process to braze aluminum alloy 5083, diffusion bonding of titanium to steel, and thermal spray application of filler metal on parts of titanium heat exchangers will demonstrate industrial applications of new joining technologies. Two presentations are devoted to flux-free soldering magnesium with the assistance of ultrasonic vibration.
