Abstract

The method includes a weld process evaluation including a first welding simulation to calculate a first weld-induced distortion in an as-designed 3D component (102) and/or an as-designed member (122) to be welded to the component. A finite element analysis calculates a distorted model (170) including a pre-weld distorted 3D component (102D) and/or a pre-weld distorted member (122D) to be generated by pre-loading fixture(s) (168) to compensate for the first weld-induced distortion in the 3D component and/or member. A second welding simulation calculates a second weld-induced distortion based on the distorted model including the pre-weld distorted 3D component (102D) and/or the pre-weld distorted member (122D). Where the second weld-induced distortion results in a product within a product specification for the welded combination, the as-designed 3D component is distorted to the pre-weld distorted 3D component and/or the as-designed member is distorted to the pre-weld distorted member, and the predefined welding process is performed.
