The welding-induced buckling distortion is one of the prime concerns in the welded thin plate panels. In this study, an analytic scheme of the plasticity-based elastic buckling prediction was proposed to assess the welding-induced buckling sensitivity of the thin plate panels. Through the scheme, the effect of the structural design and welding fab rication variables on the buckling sensitivity has been analytically investigated. Experiments were also conducted to observe the welding distortion in the test panels. It was found that buckling was unavoidable unless the heat input to the thin plates during butt welding was adequately controlled. It was noted that the buckling distortion in thin plate panels may not be satisfactorily prevented either by considering only the structural arrangement or by controlling only the welding variables. Therefore, the integrated structural design is required in addition to the consideration of welding parameters for the panel assembly. Under those circumstances, it is expected that the proposed scheme can be an effective measure to identify whether an integrated structural and welding design for the thin plate panels can be put in production or if it should be withdrawn for further engineering consideration.
