How post weld heat treatment relieves weld residual stress by yield-strength drop and creep, why thick sections and local heating bands are hard, how much stress remains for fracture and fatigue assessment, and how a simulation workflow tests a cycle before you run it.
How to simulate brazing: capillary fill and the joint gap at temperature, furnace temperature uniformity, thermal-expansion mismatch in dissimilar-metal and ceramic-metal joints, residual stress after cooling, and surrogate-assisted screening of trial loads.
Thermomechanical fatigue simulation predicts where start-stop cycles crack hot components. The physics of thermal stress, how CFD heat transfer sets the metal temperature, in-phase and out-of-phase cycles, and where AI/ML helps.
