Abstract
A method and apparatus are provided for late-customization of a valve body having an initial valve body configuration having a first end connection and a second end connection. The method includes receiving a selection of (i) a generic valve body, (ii) a first end connection, and (iii) a second end connection. The method further includes adjoining the first and second end connections to the valve body using an iterative welding process. The apparatus is configured to receive a generic valve body having an initial end configuration and to receive a different end configuration. Ends are connected to the valve body subject to an initial bias and a comparison between actual results and predicted results, and first end connection is iteratively welded.
