Dynamic thermal tensioning for welding distortion control of thin-walled T-beam structures in large PCTC shipbuilding

Longitudinal bending distortion presents a significant challenge in the manufacture of thin-walled T-beam stiffened structures common in large Pure Car and Truck Carrier (PCTC) shipbuilding. This study addresses this issue through the development and validation of an innovative dynamic thermal tensioning method. Employing thermo-elasto-plastic finite element models and a validated, temperature-dependent constitutive model, researchers investigated the formation mechanisms of distortion under varying welding speeds. Full-scale experiments demonstrated a reduction of up to 66.
