ABSTRACT:
An orbital welding apparatus includes a first housing defining a weld head assembly and a circular rotor disposed therein for rotation about a first axis. A welding electrode is carried by the rotor for welding. A second housing separate from the first housing forms a power transmission and has a second drive shaft extending therefrom. A flexible drive shaft connects the first drive shaft and the second drive shaft to conduct rotary drive forces from the first drive shaft to the second drive shaft while permitting the relative orientations of the first and second housings to be freely adjustable. A third and independent housing carries an electric drive motor and forms a power drive motor module with a rotary output shaft. A releasable clamping mechanism is provided for positioning and holding cylindrical members to be welded in an axially aligned relationship with their ends abutting in a single plane. A safety interlock mechanism is provided for sensing the releasable clamping mechanism in an operative position to prevent inadvertent operation or operation of the welding unit when the clamping mechanism is malaligned.
