Abstract
Residual tensile stresses can be mitigated through methods and systems provided by the present invention. Such a method can include securing a metal member () to a substrate and at least partially surrounding a portion of the metal member () with a cooling fluid (). As a result, the cooled portion of the metal member () contracts a predetermined amount. Once cooled, the metal member may be fixed, preferably welded, to another metal member in a constrained relationship. As the portion of the metal member is returned to its original temperature, expansion of the metal member acts to mitigate residual tensile stresses in the metal assembly. Tensile stress in restrained members, cambering, and structural deformation can be readily controlled in an assembled structure.
