Apparatus for assisting in weld assembling a box column from a tack-welded pre-assembly of planar plate components. The apparatus features (1) an elongate frame defining a rotational-assembly axis, and (2) plural pre-assembly-receiving, rotational support structures mounted at spaced locations on the frame—each support structure including (a) an openable/closable yoke possessing a collar-reception zone, (b) an openable/closable collar rotatably receivable within this reception zone, and possessing a central throughpassage having a cross-sectional configuration which is larger than that of a box-column which is to be assembled, and (c) a pair of removably-collar-attachable, throughpassage clamping shoes for forming cooperatively, within the collar throughpassage, a window for complementarily, receiving extension therethrough of a box-column pre-assembly's cross section. A so received pre-assembly is rotatable about the rotational-assembly axis to position the existing seams of adjacency between the pre-assembly plate components for full-strength welding by an automated, traveling welding instrumentality.

1. An apparatus for supporting a rectangular beam structure during a welding process, comprising a longitudinal frame structure defining a rotational axis, anda plurality of yoke structures spaced from each other along the rotational axis of the frame structure, each yoke structure containing a collar member, the collar member having a circular perimeter and an internal opening shaped to conform to the rectangular beam structure, and being rotatable inside the yoke structure about the rotational axis, each yoke structure including an upper yoke section and a lower yoke section connected to a fixed base, the upper and lower yoke sections being selectively coupled to each other at opposing lateral points near a horizontal plane, and each collar member including a pair of semi-circular collar sections,wherein each collar section is rotatable between a bottom position and a top position, and removable with the upper yoke section when the collar section is in the top position to expose upper corners of a beam while the beam is supported along sides and a bottom of the beam by the lower yoke section and the other collar section in the bottom position, wherein each collar section is comprised of identical face to face plates, each plate having a first end having a concave edge profile, and a second end having a convex edge profile, wherein each collar section includes a central plate sandwiched between two outer plates, the central plate having the first end sandwiched between the second ends of the respective outer plates, and having the second end sandwiched between the first ends of the respective outer plates. 2. The apparatus of claim 1, wherein collar sections are reversibly connected by engaging a convex end of a central plate with a slot created between convex ends of two outer plates of another collar section. 3. An apparatus for supporting a rectangular beam structure during a welding process, comprising a longitudinal frame structure defining a rotational axis, anda plurality of yoke structures spaced from each other along the rotational axis of the frame structure, each yoke structure containing a collar member, the collar member having a circular perimeter and an internal opening shaped to conform to the rectangular beam structure, and being rotatable inside the yoke structure about the rotational axis, each yoke structure including an upper yoke section and a lower yoke section connected to a fixed base, the upper and lower yoke sections being selectively coupled to each other at opposing lateral points near a horizontal plane, and each collar member including a pair of semi-circular collar sections,wherein each collar section is rotatable between a bottom position and a top position, and removable with the upper yoke section when the collar section is in the top position to expose upper corners of a beam while the beam is supported along sides and a bottom of the beam by the lower yoke section and the other collar section in the bottom position, wherein each collar member has a plurality of perimetral sockets, the lower yoke section including a latch-pin structure for selectively locking the rotational position of the collar member by engaging one of the sockets. 4. The apparatus of claim 3, wherein each collar member has two perimetral sockets at 180 degree intervals. 5. The apparatus of claim 3, wherein each collar member has four perimetral sockets at 90 degree intervals. 6. The apparatus of claim 3, wherein each collar member has eight perimetral sockets at 45 degree intervals.
