    How to prevent welding deformation

    Release Date:2016-08-16
    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.
