Abstract
A rail restraining, robotic welding and weld delivery device uses a frame for supporting a welding head with a clamp for restraining a first rail end and a second rail end and a base twist assembly for aligning said first end and second end. An interconnected weld containment apparatus pivotally connects to the clamp by use of a cam actuated linear pin. This arrangement is operable in an environment in clearance between rails and sufficiently compact that it may be operated from and carried in a truck based on a standard over the road truck or from a container.
