Abstract

To address the challenges of forming complex curved hull plates in the conventional line heating process, such as difficulties in shaping and the need for multiple corrective heat treatments, the work aims to take a typical shipbuilding saddle plate as the object and propose a novel single-pass heating technique targeted at controlling transverse deformation during forming, to eliminate subsequent corrective work, thereby enhancing both the efficiency and dimensional accuracy of the line heating process. A simulation model for predicting deformation in the line heating process was developed and validated through experiments. With this verified model, the effects of different process path strategies on controlling transverse deformation were analyzed, with a particular emphasis on comparing the proposed cross-heating path against conventional paths. The established simulation model accurately predicted deformation behavior. Under equivalent out-of-plane deformation conditions, the proposed cross-heating path significantly reduced transverse deformation, achieving only 23.5% of that observed with the conventional method. Experimental results further confirmed the path’s efficacy in suppressing transverse deformation, validating the feasibility of the “one-step forming without correction” strategy. The cross-heating path effectively controls transverse deformation during a single heating cycle, enabling efficient and precise forming of double-curved saddle plates. This approach offers a new technical direction for fabricating complex curved hull plates.
