Can I Flame Straighten 2

WebFlame straightening is carried out by rapidly heating the construction or piece locally. This causes a local deformation since the heat distribution is prevented by the surrounding cold material. When the material cools down it will shrink, correcting the deformation. The method is suitable for steel, nickel, copper, brass, aluminium and titanium. 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. WebJun 3, 2014 · You can flame straighten it, but you need to read up on it a bit.
