Legacy Post: Residual stress in linear friction welds (Dec 2016)
In a previous blog post we discussed, in general, issues related to residual stress in welding. In this post, we’ll follow up with a more detailed look at a specific welding application – linear friction welding of titanium alloys. Titanium alloys are widely used in aerospace applications for their high strength to weight ratio, good…

Legacy Post: Residual stress in welding (Sep 2016)
Welding is a very common manufacturing process that is used to join materials together to form assemblies and systems. In many cases the welded joints are large, have reduced material properties (e.g., stress corrosion cracking resistance, fracture toughness), and contain defects. The welded joints tend to be critical locations in terms of design and sustainment.…

Legacy Post: Happy Birthday to the Contour Method! (Aug 2016)
Today marks a major milestone in the field of residual stress measurement. The contour method, one of the most useful and advanced residual stress measurement techniques, was first successfully implemented on this date (August 16th) in 1999 by Mike Prime at Los Alamos National Laboratory. The most significant feature of the contour method is its…
