Abstract: Methods for verifying calibration points against mark lines on workpiece surfaces are disclosed. Other embodiments including related systems are also disclosed. A material removal component may precisely remove extraneous material from a workpiece when calibration points of the material removal component along a predetermined trajectory are aligned with a mark line upon a marked surface of a workpiece. The marked surface of the workpiece may be disposed opposite of the material removal component. By employing an optical device aligned with the material removal component, calibration points may determined along the marked surface of the workpiece and verified against the mark line. In this manner, the extraneous material may be efficiently removed while minimizing rework and/or destruction of the workpiece.

Abstract: A method of mitigating distortion in a friction stir weld joint as well as an associated friction stir weld assembly for mitigating distortion in a friction stir weld joint are provided. In this regard, a workpiece having a friction stir weld joint and associated distortion may be provided. Force may then be selectively applied to the workpiece along at least a portion of friction stir weld joint. The application of force induces plastic deformation along at least the portion of the friction stir weld joint in order to reduce the distortion of the workpiece. Force may be applied, for example, by moving a roller, such as a hardened cylindrical roller having chamfered edges, along at least a portion of the friction stir weld joint in order to apply a compressive force.
