Abstract

1464904 Pistons CATERPILLAR TRACTOR CO 20 Aug 1974 [30 Aug 19731 36602/74 Heading F2T A piston for an hydraulic pump or motor is formed in two parts, with their interconnecting weld seams 44, 45 or (37, 38, Fig. 1, not shown) in planes perpendicular to its axis. Preferably, the welds are formed simultaneously by friction or inertia welding.
