<p>A mobile welding apparatus mounted on a manipulator, suitable for use in repair of pipe by welding. The apparatus includes a first clamping mechanism for clamping an already-laid pipe, a second clamping mechanism for clamping a new pipe piece to be welded to the already-laid pipe, a mechanism for moving the second clamping mechanism in the direction of longitudinal axis of the already-laid pipe, a mechanism for moving the second clamping mechanism in the direction parallel to the vertical plane containing the longitudinal axis, a mechanism for moving the second clamping mechanism in the direction perpendicular to the vertical plane containing the longitudinal axis, and a torch rotation mechanism adapted to move along the periphery of the clamped pipe.</p> |
