Shaped by locally heating the steel plate with an oxy-acetylene flame to cause it to contract； Water and fire bending is only suitable for shaping parts with low curvature; it is more often used in combination with rolling to process parts with complex shapes that involve double bends ； There is strip heating and spot heating.
Water-fire bending is a bending method in which the sheet metal is locally and linearly heated along a predetermined heating line using an oxy-acetylene torch, and then cooled by water flow (or allowed to cool naturally), thereby inducing local plastic deformation in the sheet and bending it into the desired curved shape.

The water-fire bending plate forming method is a forming process that utilizes the local thermoplastic shrinkage deformation resulting from the localized heating and cooling of a metal plate to achieve overall bending.
The term \"water-fire bending\" is merely a colloquial expression; whether oxygen-acetylene flames, electromagnetic heating, or laser heating are used, all these methods belong to the category of heating and shaping using a moving heat source. Essentially, they all require addressing the patterns of local thermo-elastoplastic contraction deformation as well as the ways in which such deformation can be described. It is mainly suitable for the forming of single pieces or small batches of complex, large-area sheets with dual curvatures. It represents a typical dynamic nonlinear thermoelastic problem that involves factors such as material, heat source, geometric dimensions, cooling methods, and support conditions, involving extremely complex physical processes.
Definition: Shaping is achieved by locally heating the steel plate with an oxy-acetylene flame to cause it to contract. Purpose: Water and fire bending machines are suitable only for shaping parts with small curvatures; they are more often used in combination with rolling to process parts with complex shapes that require double bending. Methods: There are strip heating and spot heating.
1. Water-fire bending is a bending method in which a sheet of metal is locally and linearly heated along a predetermined heating line using an oxygen-acetylene burner, and then cooled by water flow (or allowed to cool naturally), thereby inducing local plastic deformation in the sheet and bending it into the desired curved shape. Some are **called linear heating method. Water-fire bending is currently the primary method used by most shipbuilding companies and heavy industry firms involved in steel structure manufacturing to bend plates with complex curvatures as well as large components inside ship hulls. 2. What are the uses of water and fire bending plates? Water and fire bending is only suitable for shaping parts with low curvature; it is more often used in combination with rolling to process parts with complex shapes that have double bends. 3. What are the methods for bending plates with fire and water? There is strip heating and spot heating.
Water-fire bending is a forming process that utilizes the local thermoplastic shrinkage deformation resulting from the cooling of a metal plate in certain areas, in order to achieve overall bending. The water-fire bending method is suitable only for shaping parts with low curvature; it is more often used in combination with rolling to process parts with complex shapes that have double bends. The methods of water-fire bending include strip heating and spot heating. 1# snifflily

Answer: The method of locally heating a steel plate with an oxy-acetylene flame to cause it to contract and take shape is called fire and water plate bending. Water-fire bending is only suitable for shaping parts with low curvature; it is more often used in combination with rolling to process parts with complex shapes involving double bends. The water-fire bending method includes strip heating and spot heating.
