Abstract
An orbital weldhead having minimum thickness incorporates integral cooling and includes a nonconductive housing having a circular aperture for insertion and removal of the workpiece. A nonconductive self-lubricating race is mounted in the housing and surrounds the aperture, and an integral cover adapted to mate with the housing incorporates a nonconductive outer body and an electrode plate secured to the body adjacent the nonconductive race. The electrode plate includes a machined coolant flow channel engaging the nonconductive body of the cover to form a coolant flow channel surrounding the aperture.
