In accordance with one embodiment of the present application, provided is a welding support structure arrangement to support an elongated assembled weldment preparatory to positional welding. The arrangement includes at least one support structure having a support base and a movable platform connected to the support base by spaced-apart 2-bar linkages with center pintels and a series of length adjusting members between the pintels and the support base. A length adjusting member is located between the movable platform and the support base, wherein the lengths of the length adjusting members set the orientation of the movable platform. In accordance with another embodiment of the present application, welding support structures are arranged in a linear array, wherein each of the welding support structures include a movable platform. At least some of the movable platforms of the plurality of support structures are moved to predetermined orientations. Thereafter, the workpiece is positioned onto at least some of the movable platforms of the plurality of support structures.
