Abstract
A steel pipe is welded to a threaded connector that has an end with a desired nominal inner diameter. A swage is forced over an end of the pipe, reducing an outer diameter and an initial inner diameter of the end of the pipe. A die is then forced into the end of the pipe, the die having an outer diameter sized to increase the inner diameter of the end of the pipe to the nominal inner diameter of the end of the connector. A weld groove is machined on the end of the pipe and the ends are abutted and welded at the weld grooves.
