Welding on the Hanford Site is an everyday occurrence, and most of the weldments made on site are relatively straightforward. Groove geometries, fillers, and wleding techniques and parameters are normally decided by experience or handbook advice. However, there are other weldments that might employ new materials, as well as one-of-a-kind welding situations. Implementation of a verified analytical weld assessment method would allow optimization of weld metal and heat-affected zone microstructure, and of variables that affect structural deformation and residual stresses. Realistic prediction of weldment thermal and strain history will require the use of a finite element model. Microstructure and resultant properties can be predicted using complex computer-based microstructure evolution models, literature-based empirical equations, or experimentally established behaviors. This report examines the feasibility of developing analytical methods for establishing weld parameter envelopes in new, complex welded configurations.
