Buckling distortion can be a significant problem in fabrication of stiffened thin steel panels for shipbuilding and other applications. Transient thermal tensioning (TTT) was developed to provide a practical buckling distortion control method for large, thin (< 10 mm) steel panels used in ship construction. TTT uses local heat sources that move along the plate during stiffener welding to induce zones of local residual tensile stress where weld-induced compressive zones would normally exist. Computational modelling tools have been developed which allow the optimisation of the TTT heat patterns to minimise distortion for a given combination of panel design and welding conditions.
