Abstract:
A method includes: bending a sheet about a mandrel such that the sheet is tubular, wherein the sheet includes a first longitudinal end portion and a second longitudinal end portion; engaging the first longitudinal end portion with the second longitudinal end portion; and passing the sheet between a first knurling wheel and a second knurling wheel such that the first knurling wheel applies a first knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion and the second knurling wheel applies a second knurling pattern to the sheet over the first longitudinal end portion and the second longitudinal end portion.
