Abstract
Analysis of efficiency of different shapes of heating spots in thermal straightening of thin-sheet steel structures with buckling deformations was carried out on basis of mathematical modeling. Ratio of the volume of residual plastic shrinkage strains in plane of the sheet to the heating energy input was used as a criterion of thermal efficiency of straightening. It was shown that due to optimization of the shape of heating and its parameters efficiency of thermal straightening may be increased several times.
Keywords: welded thin-sheet structures, welding deformations, thermal straightening, mathematical modeling
