The measures to prevent welding deformation mainly include the following: Firstly, rationalization of welding structure design; Secondly, select appropriate welding techniques In welding, the following process measures can be taken to reduce welding deformation: 1. Anti deformation method; 2. Thermal adjustment method; 3. City welding method; 4. Steel fixation method; 5. Hammer striking weld seam method; The boundary deformation can also be controlled by adjusting the welding sequence. Attachment: Anti deformation method: During welding assembly, the workpiece is artificially deformed in the opposite direction of the welding deformation in advance. Thermal adjustment method: Welding deformation is mainly caused by uneven heating. Reducing the width of the heat affected zone and decreasing the degree of uneven heating can reduce welding deformation.
