ABSTRACT:
In conventional track-can manufacture they are formed from symmetrical halves made (for example, by drop hammering) split along the longitudinal axis of the finished component. The conventional welding process required to complete the track-cans is then complicated due to the arcuate configuration of these components.
According to the present invention track-cans are manufactured from a plurality of substantially tubular sections, for example a cap-end (39), a body portion (43) and a flange end (40). The components are made by deep drawing from a blank cut of suitable material. The components are welded together at their interface regions to form the track-can. The tubular construction of the components enables the process of peripheral welding which in turn is comparatively simple, and particularly amenable to robotic welding. The prior art welding process was considerably more complicated due to the arcuate configuration of track-cans.
