Aluminum Honeycomb Panel Manufacturers introduced that the correction of welding distortion can be divided into cold working and hot working methods.

1. Cold working cold working method is also called mechanical correction method. It uses mechanical force to correct welding deformation. It is generally suitable for small size weldments or weldments with small deformation. Commonly used devices include jacks, presses, and straightening plates. Machine waiting. 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. Hot working The hot working method is also called flame correction method, which uses the temperature of the flame to locally heat the steel. When it cools, it produces new local deformation, thereby offsetting the old deformation and achieving the purpose of correction. The correct selection of 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. 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 bending deformation of steel beams and frame structures.
