A method for controlling distortion of a material during a weld process. The method includes modeling the weld process of the material, determining distortions produced by the weld process, determining a plurality of simulated induced distortions in the model to offset the produced distortions, generating a plurality of actual induced distortions in the material as a function of the simulated induced distortions, and performing the weld process on the material.

A method for designing a weld fixture. The method includes modeling a set of distortions produced by applied mechanical forces on a material to be welded, modeling a set of distortions produced by applied thermal forces on the material to be welded, determining a set of reaction forces at a series of locations on a simulated weld fixture as a function of the modeled distortions, and designing a weld fixture as a function of the set of reaction forces.

A mounting assembly for mounting a blade assembly to a motor grader includes an upper and a lower retainer pivotally coupled together. The upper and lower retainers are pivotable about a single axis with respect to each other for grasping the blade assembly therebetween.
