Abstract
This invention is a method of making a flanged half-bearing in which a semi-cylindrical journal bearing shell and two semi-annular end flanges are held in a jig with one flange in contact with each axial end of the shell over a part only of the thickness of the shell, and are welded together by a laser beam weld. The use of laser beam welding together with the restricted area of contact between the shell and the flanges enables the bearing to be made with very little distortion.
