Abstract: An engine piston (10) comprising a crown (12) and a tubular body portion (30) containing gudgeon pin bosses (46) and force transmitting regions (66) has the body portion forged, preferably of steel, as two or more circumferentially incomplete segments (1001, 1002) which extend about a longitudinal piston axis (14) and are joined into the tubular form by welding or the like. The segments are forged in a direction perpendicularly to the piston axis which permits the formation of regions of differing wall thickness along the tubular body length and mass saving recesses (70) between force transmitting struts (661) and (662) that are not possible with forging a unitary tubular body from one end.
