Metal Composite Panel Supplier Introduces The Welding Correction Method Of Composite Materials

There are many factors for the welding deformation of stainless steel clad plates. When the welding deformation is difficult to avoid or the deformation degree of the component exceeds the design requirement, it must be corrected. Stainless steel composite material manufacturers can rectify the usual welding deformation can be divided into cold working and hot working methods. Below, Metal Composite Panel Supplier will introduce in detail:

1. Cold working method is also called the mechanical correction method. It uses mechanical force to correct welding deformation. It is generally suitable for small size weldments or weldments with a small degree of deformation. Commonly used tools include jacks, presses, and plate leveling machines. Wait. When correcting, first fix the weldment between the supports, and then apply the force opposite to the welding deformation direction to make the opposite plastic deformation and compensate the original deformation. The cold working method is not suitable for steel materials that tend to be brittle.

2. The thermal processing method is also called the flame correction method. It uses the temperature of the flame to locally heat the steel, and when it cools, a new local deformation is generated, thereby offsetting the old deformation and achieving the purpose of correction. The correct selection of a heating position, temperature, and cooling time can get a good correction effect. The higher the heating temperature, the stronger the correction ability, and the lower the heating temperature. Generally, it should be controlled between 600-800°C and not more than 900°C. Gas welding torches are often used for heating. The hot working method is suitable for low-carbon steel structures and some ordinary low-alloy steel structures.

3. Thermal processing is subdivided into three types: point heating, linear heating, and triangular heating. Point heating is mainly used to correct the uneven deformation of the sheet. In general, the greater the thickness of the steel plate, the greater the deformation, the more heating points, the larger the diameter, and the smaller the spacing. There are three basic forms of linear heating: straight, curved, and circular heating, which should be selected as appropriate for specific applications. Triangular heating is mainly used for the bending deformation of steel beams and frame structures.
