Abstract

Experimental observations have shown that the inherent deformation produced by multi-heating lines is not a simple addition of the inherent deformation produced by single heating lines. Therefore, to accurately predict inherent deformation, the method of superposing inherent deformation of single heating lines is not appropriate. To overcome this difficulty, the authors investigate the influence of multi-heating lines on line heating inherent deformation. First, the influence of previous heating lines on inherent deformation of overlapping, parallel and crossing heating lines is clarified. The influence of the proximity to plate side edge on inherent deformation is also taken into account in the analysis. It is demonstrated that residual stresses produced by previous heating lines is the main factor influencing the inherent deformation of multi-heating lines, while the influence of the proximity to plate side edge on multi-heating lines is small and can be neglected.
