Abstract
A compact automatic pipe welding apparatus having a base member separable into three sections and having a welding unit, detecting unit and a driving unit which are distributed on the circumference of the base member at an equal distance from one another is suitable for use in welding work in limited space, as is the case of installation or repair of pipings in nuclear or chemical plant. For enhancing the welding precision, ring gears are provided for interlocking a plurality of clamping means for securing the base member to the pipe stably.
