Abstract
A trolley having an inner assembly and trolley sides is assembled by placing the components of the inner assembly in a welding fixture, welding the inner assembly components together, and welding the inner assembly to the trolley sides. The use of the fixture and the order in which the welds are carried out minimize distortion in the assembled trolley.
