How to control the distoration when you only weld from one side?

During an FSW welding operation, the shoulder brings heat to the top of the workpieces to be welded. This can cause distortion of the material which requires post-weld machining to restore the correct flatness.
To control this distortion during friction stir welding, less heat should be applied to the workpiece. To do this, it is recommended to weld faster. It is also advisable to use the smallest possible FSW tool. Our team will help you to define these welding parameters, to choose the right FSW tool and to design your clamping system.
