WebApr 23, 2003 · The easiest way to correct that is to shrink the metal in the center of the panel which is what all those spot heats do. Adding angles, or "strongbacks" to the panels will reduce the distortion somewhat, but it can't take care of all of the problem. Once you remove the angles, you will still have some of the buckling and warping. u of m helmetWebPrinciple of Flame Straightening In flame straightening, the component is precisely and locally heated to the material-specific flame straightening temperature at which plastic deformation occurs.
