techniques may prove to be particularly useful when an existing structure requires to be either stiffened or strengthened. Some advantages include:
(1) an improved fatigue detail
(2) lack of distortion from, say, the heat of welding
(3) no loss of metal section, which is inevitable with bolting.
A resulting improved fatigue detail arises through the avoidance of residual stresses, which can dominate the fatigue life of relatively thick section assemblies. In thinner section structures the consequence of these stresses is visible distortion, often requiring expensive finishing operations.
