Abstract: A precision alignment apparatus that automatically welds together the parts of a cut-apart torque converter. A precision cast and machined frame is provided onto which are mounted a spindle assembly, a double-end air cylinder and a turntable which are aligned within a close tolerance along a longitudinal axis. The spindle assembly grabs and aligns the upper half of the torque converter. The double-end air cylinder moves the spindle assembly along the longitudinal axis and provides for the longitudinal alignment of the torque converter parts. The turntable supports and aligns the lower torque converter half. The apparatus provides for automatic welding of the first part to the second part while alignment is maintained by the spindle assembly and the turntable. During welding the turntable and the spindle assembly rotate about the longitudinal axis to move the torque converter past the stationary welding device.
