Flame straightening

WebIn flame straightening, the temperature of the so-called hot spot may not exceed 450°C to avoid local tempering and deterioration of hardness. Special care must be taken in flame straightening in case the structure is intended for applications subjected to vary-ing, fatiguing loads. Examples are the vanes of fan blowers. WebSep 10, 2024 · Among the flammable gases (hydrocarbons), acetylene is typically used for flame straightening. To compensate for the welding deformations, heat source may pass through the part multiple times. Therefore, there is a relatively high risk of the repeated thermal effect reducing the heated area’s strength and toughness.
